# mesh_base


A *mesh_base* material is a [physically based material](../../../../content/materials/library/mesh_base/pbr.md) featuring PBR (physically-based rendering) and SSR (screen space reflections) technologies. It provides the realistic reflections and lighting model. The material is available in the *Materials* list and is used as the default one.


![](index.jpg)


Options available in the *States* tab enable different features thus activating additional textures and their parameters.


## Workflows


The main thing about the PBR material is a workflow. There are two workflows for Unigine PBR materials: **Metalness** and **Specular**. The specular workflow works with the old standard of textures that was used in the *[mesh_base](../../../../content/materials/library/mesh_base/index.md)* material (diffuse, specular, gloss). Metalness works with the new standard of textures (albedo, metalness, roughness).


We've kept the Specular workflow to make it easier to upgrade your projects that have the old texture standard.


We strongly recommend to use the Metalness workflow for creating materials in new projects as it uses a less number of texture channels, and material parameters of the Metalness workflow are more similar to material parameters of the real world.


By using the **Workflow** field you can specify the workflow of the material:


- **Metalness** � with the new standard of textures.
- **Specular** � with the old standard of textures.


## Deferred Buffers


**Deferred Buffers** option specifies if [deferred buffers](../../../../principles/render/sequence/index.md#forward_buffers) of the material should be filled.


## Multiple Environment Probes


**[Multiple Environment Probes](../../../../objects/lights/envprobe/index.md#multiple_env_probes)** option specifies if several Environment or Voxel Probes affect a transparent object and map their cubemaps to this object. This option should be enabled for a transparent object to be affected by [baked voxel GI](../../../../objects/lights/voxelprobe/index.md).


> **Notice:** - This option is available for [transparent materials](../../../../principles/render/sequence/index.md#transparent_multiple_env_probe_on) only (except materials with the *Alpha test* transparency preset).
> - Rendering of Multiple Environment Probes must be enabled via *Rendering -> Transparent -> Multiple Environment Probes*.


| ![](multiple_env_probe_on.png) | ![](multiple_env_probe_off.png) |
|---|---|
| *Multiple Environment Probes is on* | *Multiple Environment Probes is off* |


## Terrain Lerp


**Terrain Lerp** allows marking material to make objects be covered by projected textures of the [ObjectLandscapeTerrain](../../../../objects/objects/terrain/landscape_terrain/index.md#terrain_lerp) or [ObjectTerrainGlobal](../../../../objects/objects/terrain/terrain_global/index.md#terrain_lerp).


> **Notice:** - This option is **not available** for a terrain curved using a [geodetic pivot](../../../../objects/geodetics/geodeticpivot/index.md).
> - For appropriate projection, the position of an object should be within the borders of the Global Terrain along the **X** and the **Y** axis.


| ![](terrain_lerp_1.png) | ![](terrain_lerp_2.png) |
|---|---|
| *Terrain Lerp is off* | *Terrain Lerp is on* |


> **Notice:** Meshes with Terrain Lerp enabled get only visual appearance of the terrain (Albedo, Normal and Detail textures) and are ignored by such CPU-based features as [physics simulation](../../../../principles/physics/index.md) and [vegetation generation](../../../../editor2/sandworm/workflow/vegetation/index.md). To enable these features for your mesh, you should adjust physics settings or [WorldClutter](../../../../objects/worlds/world_clutter/index.md)/[MeshClutter](../../../../objects/objects/mesh_clutter/index.md)/[Grass](../../../../objects/objects/grass/index.md) interaction for it manually.


## Emission


**Emission** simulates glow from extremely bright surfaces, therefore imitating real light sources and highlights. It can be used, for example, to simulate a glow of distant objects. Enabling the option activates an additional emission texture.

> **Notice:** Lighting from sources simulated using the Emission state can be [baked](../../../../editor2/lighting/gi/index.md#static_gi) into GI.


![](emission_img.png)

*Light in windows simulated byEmission*


### Emission Texture


**Emission** map stores information about the light [emission](#option_emission). It is blended additively over a texture, so areas which do not glow at all should be pure black on the glow map, and any brighter colors will appear to be emitting light.


| [![](emission_wo_texture_sm.png)](emission_wo_texture.png) | [![](emission_w_texture_sm.png)](emission_w_texture.png) |
|---|---|
| *Emission state disabled* | *Emission state enabled, with emission texture* |


The texture is 3-channeled.


- *RGB* values store information about a glowing color.


### Emission Parameters


![](emission_params.png)

*Emission parameters*


#### Color


**Color** is a color picker to choose a color multiplier for the [emission texture](#texture_emission).


#### Scale


**Scale** is a coefficient to scale emission texture intensity. The higher the value, the lighter and brighter light areas of the emission texture are.


## Cross Section


**Cross Section** enables rendering of cross-sections of an object to which the material is applied (can be useful for complex CAD models).


> **Notice:** Cross sections are rendered only if the *[Two Sided](../../../../editor2/materials_settings/index.md#two_sided)* option and the *[Emission](#option_emission)* state are enabled.


A cross-section of the object is created by the near clipping plane of the camera (player) viewing frustum that cuts this object. If the camera's near clipping plane is *[oblique](../../../../api/library/players/class.player_cpp.md#setObliqueFrustum_int_void)*, you can [change its obliqueness](../../../../api/library/players/class.player_cpp.md#setObliqueFrustumPlane_Vec4_void) and, therefore, change transformation of the cross-section. All plane sections are highlighted with a [color](#parameters_cross_section_color).

> **Notice:** If geometry of the object has intersecting parts, in the cross points both the back and front faces of the polygons will be rendered.


![](cross_section.gif)

*Cross Section of An Object*


### Cross Section Color


**Cross Section Color** specifies a color for a plane section (an area created by a plane cutting through a solid).


## Ambient Occlusion


**Ambient Occlusion** ([SSAO](../../../../principles/render/sequence/index.md#ssao)) is a real-time imitation of the diffuse indirect light and its shadows.


Enabling the option activates the *[Ambient occlusion](#uv_ao)* field that specifies which UV coordinates of the mesh will be used for textures.


### Ambient Occlusion Texture


**Ambient occlusion** (AO) texture modulates the global environment illumination, for example, when an object is lighter at the top from sky above, and darker at the bottom from the ground below.


| [![](ao_wo_texture_sm.png)](ao_wo_texture.png) | [![](ao_w_texture_sm.png)](ao_w_texture.png) |
|---|---|
| *Without AO texture* | *With AO texture* |


The texture uses only *R* channel.


### Ambient Occlusion Parameters


#### UV Transform AO


**UV Transform AO** is an ambient occlusion texture transformation [parameter](#texture_transform).


## Auxiliary Buffer


**Auxiliary** activates the auxiliary texture and parameters.


### Auxiliary Texture


**Auxiliary texture** is a texture that used for [auxiliary rendering pass](../../../../principles/render/sequence/index.md#auxiliary).


### Auxiliary Color


![](auxiliary_params.png)

*Auxiliary color parameter*


**Auxiliary** color parameter specifies the constant color for the auxiliary pass.


## Vertex Color


The vertex color is a color assigned to each vertex of the 3D model in any third party 3D editor. After being imported to Unigine, such model can be used in a number of ways allowing you to reduce the amount of used texture and broaden the diversity of the final materials.


The **Vertex color** checkbox enables an additional *Vertex color* options field used for per channel modulation of the albedo, AO, emission, detail and auxiliary textures.


> **Notice:** To use vertex color for emission, auxiliary and detail textures, the [Emission](#option_emission), [Auxiliary](#option_auxiliary) and [Detail](#option_detail) states should be enabled first.


![](vertex_color.png)

*The Vertex color field*


For the AO and detail textures, you can choose which texture channel (R, G, B or A) to use. For albedo, emission, and auxiliary textures, RGB channels are used simultaneously.


For example, using the vertex color of the albedo texture allows you to create a detail material. At the pictures below there is a model containing vertex colors (brown spotted). Left to right:


1. No texture is used, **Vertex color** is disabled.
2. No texture is used, **Vertex color** is enabled, the **Albedo** **RGB** mode is used.
3. The diffuse texture (light wood) is assigned, **Vertex color** is enabled, **Albedo** **RGB** mode is used.

|---|---|---|


## Planar Reflections


The *mesh_base* material features a dynamic planar reflection technique for transparent materials (*Alpha Blend, Additive, Multiplicative* transparency presets). The reflecting power of the material depends on two parameters: metalness and roughness.

> **Notice:** This option is available **for transparent materials only**, planar reflections for opaque materials are implemented via the *[Light Planar Probes](../../../../objects/lights/planar/index.md)*


By using planar reflection options, you could create flat mirrors and flat dynamic reflective surfaces: parquet, flat varnished surfaces, etc.


![](planar_scheme.png)

*Schematic representation of planar reflections*


The engine renders dynamic reflections for planar reflection by computing the position of the reflection camera. Reflection camera represents a camera on the other side of the reflective surface: the distance from reflector to camera is the same for real camera and reflection camera.


> **Notice:** For the purposes of optimization, shadows of the object will be shown even if the object won't be reflected due to [reflection distance](#planar_distance) parameter. That happens because planar reflections re-use the shadows which were rendered for the real camera.


Planar reflections don't reflect each other: they render [environment cubemap](../../../../editor2/settings/render_settings/environment/index.md) instead. Also, planar reflections miss post-effects.


To enable planar reflections for the transparent material, click the **Planar Reflection** checkbox (available for *Alpha Blend, Additive*, and *Multiplicative* transparency presets). After enabling the option, the additional *Planar Reflection* group becomes available. Ensure that the material has dynamic reflections. If not, tune the following parameters: **Metalness** and **Roughness** for metalness workflow, **Microfiber** and **Gloss** for specular workflow.

> **Notice:** To render planar reflections, you must enable *Dynamic reflections* via *Rendering -> Features -> Dynamic reflections*.


![States](planar_reflections.png)

*Material window,Statestab.*


### Map Size


Specifies the size of the reflection map: the higher the value, the better the quality.


Available sizes of the map are:


- **128** � creates a reflection image with 128x128 resolution.
- **256** � creates a reflection image with 256x256 resolution.
- **512** � creates a reflection image with 512x512 resolution.
- **1024** � creates a reflection image with 1024x1024 resolution.
- **2048** � creates a reflection image with 2048x2048 resolution.
- **4096** � creates a reflection image with 4096x4096 resolution.
- **Quart height** � creates a reflection image with the resolution *height/4* x*height/4*, where height is an application window height.
- **Half height** � creates a reflection image with the resolution *height/2* x*height/2*, where height is an application window height.
- **Height** � creates a reflection image with the resolution *height* x*height*, where height is an application window height.


### Two Sided


The **Two Sided** option enables a two-sided planar reflection.


### Show Pivot


The **Show Pivot** option shows the pivot plane, which shows the direction of reflective surface. By specifying the direction of planar reflection, you can create a reflection surface even if it was exported at an angle.


![](planar_pivot.png)


### Blur


The **Blur** option enables blurring of the planar reflection texture making reflections look more plausible.


| ![](planar_reflection_blur_0.png) | ![](planar_reflection_blur_1.png) |
|---|---|
| *Blur disabled* | *Blur enabled* |


### Planar Reflection Parameters


The set of planar reflection parameters (available on the *Parameters* tab):


![](planar_parameters.png)


#### Viewport Mask


**Viewport Mask** specifies the [viewport mask](../../../../principles/bit_masking/index.md#viewport) of the reflection camera.


#### Distance


**Distance** from the reflection camera to the reflected object. In other words, the distance equals the distance from camera to the reflective surface plus the distance from object to reflective surface.


![](planar_scheme.png)


#### Distance Scale


Global distance multiplier for the reflection visibility distance. Distance Scale is applied to the distance measured from the reflection camera to the node's (surface's) bound.
 This option allows a developer to increase rendering performance by using less detailed LODs for reflections or reducing the number of reflected nodes.
 Increasing the value leads to decreasing performance.


#### Pivot Rotation


**Pivot Rotation** specifies the rotation of the reflection pivot point.

> **Notice:** This parameter can be used to correct reflection if reflective surface was exported with a tilt angle or was rotated.


#### Pivot Offset


**Pivot offset** specifies the position of the pivot point.

> **Notice:** This parameter can be used to correct reflection if the transformation of reflective surface was changed.


## Vegetation


The *mesh_base* material allows creating materials for vegetation foliage and stems. Enabling the **Vegetation** checkbox activates a set of additional animation and geometry parameters.


![](vegetation.png)


### Animation


Enables vegetation animation. The available values are:


- **Disable** � the material is static.
- **Default** � animation of stems and leaves is enabled and can be controlled by the [animation parameters](#animation_parameters).
- **Field** � animation of stems and leaves is enabled, can be controlled by the [animation parameters](#animation_parameters), and the material's animation parameters can be affected by the [animation field](../../../../objects/effects/fields/field_animation/index.md).


### Leaves


**Leaves** specifies the way to render the leaves geometry:


- **Disable** � leaves are not rendered.
- **Billboard** � leaves are rendered as billboards that always face the camera. This is the most performance-friendly way of animating distant vegetation. Animation uses UV channel 2 of an object as follows: in the UV grid, [0,1] is the pivot point for the billboard's movements, and the billboard's size can be changed by scaling the polygon in the UV channel. If a billboard object uses the below UV map for animation, it would be represented by three objects rotating around their centers. | ![](billboard_uv.png) | ![](billboard_uv.gif) | |---|---|
- **Geometry UV-based** � leaves are rendered as standard polygons. Animation uses UV channel 2 of an object as follows: in the UV grid, [0,1] is the pivot point for the object's movements and the stiffest part of the object, and towards [1,0], the object becomes more flexible. In the diagram below, the stiffest part of the object is against the white background, and the most flexible���against the blue background. | ![](leaf_mesh_uv.png) | ![](geometry_uv.gif) | |---|---|
- **Geometry Vertex Color based** � leaves are rendered as standard polygons; vertex colors are used for animation. Vegetation movements are configured using RGB channels as follows: | ![](R_channel_veg.png) | Red channel is used for animation of smaller or peripheral parts of vegetation (leaves). Bright parts are animated, and dark parts are not animated. | |---|---| | ![](G_channel_veg.png) | Green channel is used to define the movement order for branches in order to desynchronize them. The movement sequence starts from the brightest element to the darkest. | | ![](B_channel_veg.png) | Blue channel is used to define which parts of branches can be bent. Brigher parts indicate bendable portions, and darker parts���stiff portions. |


> **Notice:** If leaves are rendered, their animation is controlled by the [animation parameters](#animation_parameters).


#### Examples


| ![](animation_billboards.gif) | ![](animation_uv.gif) | ![](animation_vertex.gif) |
|---|---|---|
| *Animation -> Enable* *Leaves -> Billboard* | *Animation -> Enable* *Leaves -> Geometry UV-based* | *Animation -> Enable* *Leaves -> Geometry Vertex Color based* |


### Shadow Offset


**Shadow offset** enables an offset parameter for leaves shadows.


### Vegetation Velocity


**Vegetation Velocity** enables rendering of vegetation animations to the velocity buffer. Can be used to improve TAA and Motion Blur result when necessary. In other cases you can disable this option to gain performance (as objects with this option enabled are rendered twice).

> **Notice:** When disabled the material shall not be rendered to velocity buffer at all.


### Vegetation Parameters


#### Animation Parameters


Animation parameters are available on the *Parameters* tab if the *[Animation](#vegetation_animation)* option is enabled.


![](animation_params.png)

This mask must match the field mask of the [animation field](../../../../objects/effects/fields/field_animation/index.md#editing). > **Notice:** The Field Mask parameter is available only if the *Animation* state is set to *Field*.


If [leaves](#vegetation_leaves) are rendered, the following animation parameters are also available:


![](animation_params_vertex.png)

*Animation parameters,Parameterstab*


- **Leaves Noise Scale** � a coefficient to randomize the orientation and direction of rotation for leaves (seen only on several nodes with the same material). By the minimum value of **0**, all leaves are synchronized in their movement. Higher values make leaves randomly move in different directions. | ![](leaves_noise_billboard.gif) | ![](leaves_noise_uv.gif) | ![](leaves_noise_vertex.gif) | |---|---|---| | *Leaves Noise Scale: 50.0* | *Leaves Noise Scale:1.0, 10.0, and 20.0* | *Leaves Noise Scale: 0.0 and 3.0* |

- **Leaves Animation Speed** � a coefficient to scale the speed of leaves rotation. By the minimum value of **0**, leaves do not move at all. Higher values make leaves move faster. | ![](leaves_anim_billboard.gif) | ![](leaves_anim_uv.gif) | ![](leaves_anim_vertex.gif) | |---|---|---| | *Leaves Animation Speed:0.765 and 2.287* | *Leaves Animation Speed:0.0, 1.0, and 4.0* | *Leaves Animation Speed: 2.0 and 5.0* |
- **Branch Offset** � a coefficient to scale the rotation amplitude for a whole branch. Available for the [vertex color based geometry](#vegetation_animation_vertex) only. ![](branch_offset_vertex.gif) *Branch Offset: 0.1 and 0.3*

| ![](shadow_offset_0.png) | ![](shadow_offset_1.png) |
|---|---|
| *Shadow offset = 0.0* | *Shadow offset = 0.1* |


## Mip Bias


Mip bias activates an additional Mip Bias parameter. It is used to adjust MIP mapping.


### Mip Bias Parameter


![](mip_bias.png)


Coefficient for MIP maps adjustment.


## 2D Noise


**2D noise** enables a spatial color noise based on a 2D texture. Enabling the option activates the following texture and parameters:


### 2D Noise Texture


A color noise 2D texture.


![](2d_noise_texture.png)

*Example of the 2D noise texture*


### 2D Noise Parameters


![](2d_noise_params.png)

*2D noise parameters*


#### Intensity


Noise texture intensity. By the maximum value of 1, the color noise is fully visible.


| ![](2d_noise_intensity_0.png) | ![](2d_noise_intensity_1.png) | ![](2d_noise_intensity_2.png) |
|---|---|---|
| *Intensity = 0.0* | *Intensity = 0.5* | *Intensity = 1.0* |


#### UV Transform


Noise texture native [coordinates transformation](#texture_transform) represented by a vector of the four float components.


## 3D Noise


**3D noise** specifies if additional spatial noise and color gradient textures will be added. These textures add a random color variation to leaves.


| ![Without Color noise](3d_noise_disabled.png) | ![With Color noise](3d_noise_transform_0.png) |
|---|---|
| *Disabled 3D noise* | *Enabled 3D noise* |


Enabling the option activates the following textures and parameters:


### 3D Noise Textures


#### 3D Noise Texture


A single channeled spatial color noise texture used to randomize the coloring of leaves according to the [gradient color texture](#texture_gradient).


![Color noise texture](color_noise_texture.jpg)

*Example of the 3D color noise texture (rotated and cut)*


#### Color Gradient


A gradient texture that modulates leaves colors (for example, from bright green to yellow). **0.5** means the texture does not affect leaf color. Higher values lighten the colors (are added). Lower values darken the colors (are subtracted).


![Color gradient](color_gradient.jpg)


### 3D Noise Parameters


#### Intensity


Noise texture intensity. By the maximum value of 1, the color noise is fully visible.


| ![](2d_noise_intensity_0.png) | ![](3d_noise_intensity_0.png) | ![](3d_noise_intensity_1.png) |
|---|---|---|
| *Intensity = 0.0* | *Intensity = 0.5* | *Intensity = 1.0* |


#### UV Transform


Noise texture native coordinates transformation along *X*, *Y* and *Z* axes. A vector of the three float components:

- By high values, color blobs are small in size (for example, several blobs per leaf). Tiles of the spatial noise texture are small and repeat often
- By low values, color blobs are big (for example, several blobs for the whole tree). Tiles of the spatial noise texture are big and repeat a few times


| ![Smaller tiles](3d_noise_transform_0.png) | ![Larger tiles](3d_noise_transform_1.png) |
|---|---|
| *UV transform = vec3(0.1)* | *UV transform = vec3(0.01)* |


## Detail Rendering


**Detail** rendering activates a set of textures (diffuse, normal, specular for the Specular workflow; albedo, normal and shading for Metalness workflow) to form a material layer. It is applied for bringing detailing to the material.


Available options are (when the state is enabled):


![](option_detail_enabled.png)


- **Blending** � the type of the detail material blending. | ![](detail_alpha_blend.png) | ![](detail_overlay.png) | ![](detail_multiply.png) | |---|---|---| | *Alpha blending mode* | *Overlay mode* | *Multiply mode* |

  - **Alpha blend** � an [alpha blending](../../../../principles/render/blending/index.md#formula) mode.
  - **Overlay** - depending on the base texture (diffuse or albedo) color, the base and detail textures colors are either multiplied (for dark color pixels) or screened (for light color pixels), which leads to the contrast increase while preserving highlights and shadows. Grey pixels are not effected at all.
  - **Multiply** � the base texture (diffuse or albedo) color is multiplied by the detail texture color, resulting in darker colors. White pixels are not effected at all. > **Notice:** If detail textures are not visible enough in the resulting image, try increasing its color scale parameter (**Diffuse** or **Albedo**).
- **Angle fade** � detail angle fade.

  - **Disable** � disable overlapping of the base material.
  - **Object transform (overlap)** � overlap the base material by using the object transformation (detail textures will be rotated with the mesh). This option can be used to create stone material with moss, rust and corrosion atop. | ![](overlap_object_0.png) | ![](overlap_object_1.png) | |---|---| | *Base albedo texture* | *Detail albedo texture* |
  - **World transform (overlap)** � overlap the base textures by using the world transformation (no matter if you rotate the object, the detail textures will always be projected atop). This option can be used to create stone material with moss, rust and corrosion atop. | ![](overlap_world_0.png) | ![](overlap_world_1.png) | |---|---| | *Base albedo texture* | *Detail albedo texture* | > **Notice:** These two overlap options (*Overlap (object transform)* and *Overlap (world transform)*) replaced the old *mesh_overlap_base* material.
- **Mask** � a flag indicating that a texture mask is used for blending base and detail materials selectively (the detail textures will be shown according to the mask). > **Notice:** This option replaced the old *mesh_layer_base* material. Enabling the mask activates the *[Detail mask](#uv_mapping)* field that specifies which UV coordinates of the mesh will be used for the detail mask.
- **Normal Substitute** � enabling this flag makes the [detail normal texture](#textures_detail) overlap the [base normal texture](#texture_normal_met). If disabled, the base and detail normal maps are combined. ![](normal_substitute_off.jpg) ![](normal_substitute_on.jpg)


> **Notice:** See also the chapters on [detail texures](#textures_detail) and detail textures [shading parameters](#detail).


## Procedural Effects


Enables use of procedural effects: [SSBevel](../../../../editor2/settings/render_settings/ssbevel/index.md) and [SSDirt](../../../../editor2/settings/render_settings/ssdirt/index.md).


## SSBevel


![](bevel.png)

*SSBevel,Statestab*


**SSBevel** enables rendering of the screen-space bevels for the material.

> **Notice:** Requires the [**Procedural Effects**](#option_procedural) option to be enabled.


![](ssbevel_0.png) ![](ssbevel_1.png)


### Procedural Texture


Texture used for procedural effects, such as SSBevel and [SSDirt](#option_ssdirt).


The texture is 3-channeled:


1. *R* - SSBevel map, defines areas where the SSBevel effect is applied. For example, if you specify the noise texture, bevels will look as follows: ![](bevel_texture_0.png) ![](bevel_texture_1.png)
2. *G* - cavity mask for the [SSDirt](#option_ssdirt) effect.
3. *B* - convexity mask for the [SSDirt](#option_ssdirt) effect.


### SSBevel Parameters


#### Scale


**Scale** is a multiplier for the bevel's [radius](../../../../editor2/settings/render_settings/ssbevel/index.md#radius).


#### SSBevel UV Transform


**SSBevel UV Transform** sets [coordinates transformation](../../../../content/materials/library/mesh_base/index.md#texture_transform) for the SSBevel map. To specify which UV coordinates of the mesh should be used for the bevel texture, go to the *States* tab and set the *[SSBevel](#uv_bevel_map)* value in the **UV Mapping** section.


#### Triplanar Blend


**Triplanar Blend** - triplanar blending factor.

> **Notice:** The parameter is available when the Triplanar mapping is used to project the texture.


## SSDirt


![](ssdirt.png)

*SSDirt,Statestab*


**SSDirt** enables rendering of the [SSDirt](../../../../editor2/settings/render_settings/ssdirt/index.md) effect for the material, allowing you to simulate worn scratched edges and accumulation of dirt and dust in cavities.

> **Notice:** Requires the [**Procedural Effects**](#option_procedural) option to be enabled.


![](ssdirt_0.png) ![](ssdirt_1.png)


This effect uses the [Procedural texture](#texture_procedural) described above.


### SSDirt Parameters


#### Cavity Scale


Scale factor for the SSDirt effect in concave areas. *Higher* values result in more pronounced effect in slits and cavities.


![](ssdirt_cavity_scale_07.png) ![](ssdirt_1.png)


#### Convexity Scale


Scale factor for the SSDirt effect in convex areas. *Higher* values result in more pronounced effect on edges and convexities.


#### Curvature UV Transform


[UV-coordinates transformation](#texture_transform) for textures applied in concave and convex areas.


## Normal Map


![](normal_map.png)

*Normal map,Statestab*


**Normal map** specifies the type of normal mapping that is used for a model.


- **Object space** normal maps are characterized by their full spectrum (rainbow-colored) appearance. They are used for meshes vertices of which cannot be deformed (the model must remain in its original orientation). Object space normals are best for things that can move, but cannot be deformed, like walls, doors, cars, weapons, etc. It's easier to generate high-quality curvature because object space normal map completely ignores crude smoothing of the low-poly vertex normals.
- **Tangent space** normal maps are easily recognized by their mostly blue appearance. Tangent Space normal maps can be rotated and deformed, therefore they are ideal for characters or objects that need to have vertex deformation, like water or tree limbs.


## Opacity Map


![](opacity_map.png)

*Opacity map,Statestab*


**Opacity map** indicates the alpha channel of which texture to use:

> **Notice:** The state is available for transparent objects only.


- **Main** - use the alpha channel of the main (albedo or diffuse, depending on the current workflow) texture.
- **Normal** - use the B channel of the normal map.


## Lightmap Cubic Filtering


**Lightmap Cubic Filtering** enables cubic filtering for the [lightmap](../../../../editor2/lighting/gi/lightmaps.md) assigned to the surface, if any. If disabled, linear filtering for the lightmap is used.


## Reflection Cubic Filtering


**Reflection Cubic Filtering** enables bicubic interpolation for the surface reflection in the Enviropment Probe cubemap with the *[Reflection Cubic Filtering](../../../../objects/lights/envprobe/index.md#cubic_filtering)* option enabled. The effect is calculated if a pixel has a low *[Roughness](#parameter_roughness)* value. If disabled, bilinear interpolation for the reflection is used.


> **Notice:** The state is available for *transparent* materials only.


## Specular Map


**Specular** map enables using a [specular texture](#texture_specular_channel) channel of the [shading texture](#texture_shading) as a specular multiplier.


> **Notice:** The state is available for the *Metalness* workflow only.


## Specular Anti-Aliasing


**Specular AA** enables anti-aliasing of specular highlights. This anti-aliasing is performed by increasing roughness at places where normals change their orientation. Geometry of the model is used, the normal map is not required.


![](specular_aa_off.png) ![](specular_aa_on.png)


### Specular AA Parameters


![](specular_aa_params.png)

*Specular AA parameters*


| Intensity | Strength of the specular anti-aliasing effect between 0 and 1. Higher values produce a blurrier result with less aliasing. |
|---|---|
| Threshold | Maximum value for the offset to be subtracted from the smoothness value to reduce artifacts. |
| Albedo Impact | Intensity of darkening the albedo on metal surfaces. |
| Specular Impact | Intensity of darkening the specular on dielectric surfaces. |
| Roughness Impact | Intensity of roughness. |


## Microfiber Map


When the *Metalness* workflow is used, the **Microfiber** state activates the [microfiber texture](#texture_microfiber_channel) channel in the [shading texture](#texture_shading).


When the *Specular* workflow is used, the **Microfiber** state activates the [microfiber texture](#texture_microfiber).


In the example below, on the first picture, only a part of the mesh is napped according to the microfiber texture. On the second picture, the whole mesh is napped as the microfiber texture doesn't define otherwise.


| ![](microfiber_enabled.png) | ![](microfiber_disabled.png) |
|---|---|
| *Microfiber state enabled* | *Microfiber state disabled* |


## Translucent Map


**Translucent** map activates an additional [translucent texture](#texture_translucent).


### Translucent Texture


**Translucent texture** stores information on material's translucency. For example, by using this texture, it is possible to specify parts of the object that aren't translucent (the *[Translucent](#parameter_translucency)* parameter won't affect them).


The texture is single-channeled.


In the example below, the following texture is used:


![](translucent_texture.png)

*Translucent texture*


| ![](translucent_texture_simple_0.png) | ![](translucent_texture_simple_1.png) | ![](translucent_texture_simple_2.png) |
|---|---|---|
| *Translucence is disabled* | *Translucent = 1.0, no translucent texture is used* | *Translucent = 1.0, translucent texture is set* |


The texture can be used, for example, to specify non-translucent areas of vegetation:


| ![](translucent_0.png) | ![](translucent_1.png) | ![](translucent_2.png) |
|---|---|---|
| *Translucence is disabled* | *Translucent = 1.0, no translucent texture is used* | *Translucent = 1.0, translucent texture is set* |


| ![](translucent_0_big.png) | ![](translucent_1_big.png) | ![](translucent_2_big.png) |
|---|---|---|
| *Translucence is disabled* | *Translucent = 1.0, no translucent texture is used* | *Translucent = 1.0, translucent texture is set* |

![](displacement_options.png)

*Displacement options*


**Displacement** includes the following options:


- **[Parallax Occlusion Mapping](#parallax_mapping)**
- **[Tessellated Displacement](#tessellated_displacement)**
- **[Tessellated Vector Displacement](#tessellated_vector_displacement)**


### Parallax Occlusion Mapping


**Parallax Occlusion** enables the parallax effect that provides a convex relief based on a [parallax](#texture_parallax) (height) texture.


| ![](parallax_bricks_0.png) | ![](parallax_bricks_1.png) |
|---|---|
| *DisabledParallax Occlusion* | *EnabledParallax Occlusion* |


Available options are:


![](parallax_options.png)

*Parallax options*


- **Depth cutout** - apply the depth cutout effect that provides smooth connection of the object with the real mesh. The option enables to make a plane looks like real geometry. Also, the depth cutout effect improves the SSAO calculation on surfaces with parallax maps. | ![](parallax_depthcut_0.png) | ![](parallax_depthcut_1.png) | |---|---| | *DisabledDepth cutout* | *EnabledDepth cutout* |
- **Cutout** - apply the cutout effect that provides smooth edges between the opaque and transparent areas. > **Notice:** This effect works correctly only when mesh edges match the UV edges. | ![](parallax_cutout_0.png) | ![](parallax_cutout_1.png) | |---|---| | *DisabledCutout* | *EnabledCutout* |


#### Parallax Texture


**Parallax map** stores information about per-pixel [parallax](#parallax_mapping) displacement.


The texture uses only *R* channel:


- **White** color indicates that the pixels are not displaced.
- **Black** color indicates that the pixels will be depressed farthest away.


#### Parallax Parameters


![](parallax_params.png)

*Parallax parameters*


##### Parallax Height


**Height** is a coefficient to scale the power of the [parallax texture](#texture_parallax) displacements. The higher the value, the bigger the normals are.


| ![](parallax_height_0.png) | ![](parallax_height_1.png) | ![](parallax_height_2.png) |
|---|---|---|
| *Height = 0.01* | *Height = 0.03* | *Height = 0.05* |


##### Min Layers


**Min layers** parameter specifies the minimum step of the parallax mapping.


##### Max Layers


**Max layers** parameter specifies the maximum step of the parallax mapping.


##### Noise


**Noise** parameter specifies the size of the noise used for parallax mapping. The higher the value, the less visible the layers.


##### Cutout UV Transform


Parallax texture [coordinates transformation](#texture_transform).


> **Notice:** The parameter is available if the *Cutout* option is enabled.


### Tessellated Displacement


**Tessellated Displacement** provides a true convex relief by enabling Adaptive Hardware-accelerated Tessellation that subdivides lower-polygon surfaces into finer meshes, which are displaced along the local surface normal based on a [Displacement](#texture_displacement) (height) texture.


| ![](tessellation_0.png) | ![](tessellation_1.png) |
|---|---|
| *DisabledTessellated Displacement* | *EnabledTessellated Displacement* |
| ![](tessellation_2.png) | ![](tessellation_3.png) |
| *DisabledTessellated Displacement(wireframe)* | *EnabledTessellated Displacement(wireframe)* |


#### Authoring Tips


Tessellation is intended to add extruded details (spikes and indentations, fine embossed details) rather than drastically change the relief of the coarse mesh. Tessellated Displacement does not affect vertex normals and texture coordinates, so extreme extrusion makes it prone to noticeable visual artifacts, such as texture stretching and inaccurate lighting.


> **Notice:** Please note that tessellated polygons do not take part in intersection and collision detection.


The displacement is applied along the surface normal so tessellated meshes composed of separate parts with hard edges are prone to cracking. To avoid such artifacts, it is recommended to make sure the portions share vertices and edges and have smooth or matching tangents. Another solution would be to create additional polygons that will cover cracked areas from the inside.


![](tessellation_hardnormals_tearing.gif)

*Cracking on a box with separate faces*


Also, displacement applied to polygons from divergent UV shells results in small yet noticeable inconsistency. A decent solution is to paint similar color values on adjacent pixels of divergent UV shells to make sure the Displacement texture doesn't change on junctions.


![](tessellation_displacement_cracking.png)

*Displacement map cracking*


The Displacement effect is bound to the scale of the node, so be careful when dealing with meshes that have different scale but share the same material with Tessellated Displacement enabled. Once combined for optimization purposes, the tessellation scale on such meshes may become significantly different. So such meshes are to be treated separately.


![](tessellation_displacement_scale.jpg)

*The same displacement scale on combined scaled meshes*


#### Tessellation Options


Available options are:


![](tessellation_options.png)

*Tessellation options*


- **Shadow** - enable shadow casting from tessellated polygons. This option doubles the number of rendered tessellated polygons, so it is recommended to use it carefully. | ![](tessellation_shadow_0.png) | ![](tessellation_shadow_1.png) | |---|---| | *DisabledShadow* | *EnabledShadow* |
- **Density Map** - enable tessellation density control based on the [Tessellation Density Map](#texture_tessellation_density) texture. Lighter pixels of the Density map indicate polygons that should be tessellated more densely. > **Notice:** The Density Map is sampled at vertices of the control mesh. If the darkened area is too small to cover control mesh vertices, it will not affect the final result. | ![](tessellation_density_0.png) | ![](tessellation_density_1.png) | |---|---| | *DisabledDensity Map* | *EnabledDensity Map* |


#### Displacement Texture


**Displacement Texture** (height map) stores information about per-pixel [Tessellated Displacement](#tessellated_displacement).


The texture uses only *R* channel:


- **White** color indicates that the pixels will be extruded farthest out.
- **Black** color indicates that the pixels will be depressed farthest away.

 Best PracticeFor better quality, it is recommended to use a normalized displacement texture, so black pixels correspond to the most depressed areas and white pixels correspond to the most extruded areas.
| ![](tessellation_displacement_texture_0.jpg) | ![](tessellation_displacement_texture_1.jpg) |
|---|---|
| *Unnormalized displacement texture* | *Normalized displacement texture* |


#### Tessellation Density Map


**Tessellation Density Map** stores information about areas that should be [tessellated more densely](#tessellation_option_density_map).


The texture uses only *R* channel:


- **White** color corresponds to the maximum tessellation density.
- **Black** color corrseponds to the minimum tessellation density.

**Texture Exponent** parameter specifies the gamma of the [Displacement](#texture_displacement) texture.


##### Shadow Offset


**Shadow Offset** sets an offset of shadows for fine-tuning.

##### Density


**Density** is coefficient for subpixel reduction of polygons. The value of 1 corresponds to the highest mesh density defined by the [Factor](#tessellation_density_factor) parameter.


> **Notice:** Although lower values help significantly reduce the number of polygons and improve the performance, be careful as visual artifacts may appear when the camera moves. To get rid of wiggling and keep the small number of polygons, it is recommended to increase the **Density** and decrease the **Factor** values.


| ![](tessellation_density_density_0.jpg) | ![](tessellation_density_density_1.jpg) |
|---|---|
| *Density = 0.1; Factor = 0.5* | *Density = 1.0; Factor = 0.5* |

## Calculate Tangent Space


**Calculate tangent space** enables calculating the tangent space in the shader. It can be used for materials applied to geometry with incorrect tangents or to geometry without tangents.


## Normals Rotated to Camera


If enabled, **Normals Rotated to Camera** makes all normals of the surface oriented towards the camera ignoring the geometry normals. This option can be used for vegetation to make the fact that leaves and grass blades are composed of polygons less noticeable.

![](normals_rotated_to_camera_off.jpg) ![](normals_rotated_to_camera_on.jpg)


## Backside Normal


**Backside Normal** enables you to choose the orientation of normals for the back sides of polygons.

Available options are:


- **To Back Side** - when seen from the back, the polygon is lit normally according to the normal of the back side.
- **To Front Side** - the back side of the polygon is lit the same way as the front side, creating an effect of a thin translucent material.


![](backside_normal_back.png) ![](backside_normal_front.png)


## Geometry Inflation


**Geometry inflation** allows you to apply an additional visual effect without real geometry changing. By using this option, you can create wires and balloons by specifying the type of inflation.

### Lerp Cascades


**Lerp Cascades** enables linear interpolation for shadows cascades. When enabled, transitions between cascades become smoother. However, the option drops performance, as in the transition parts 2 shadow maps are rendered.

> **Notice:** For this feature to work properly linear interpolation of shadow cascades should be [enabled globally](../../../../editor2/settings/render_settings/shadows/index.md#lerp_shadow_cascades) (via *Rendering -> Shadows -> Lerp Shadow Cascades*).

- **Low** � low quality
- **Medium** � medium quality
- **High** � high quality

> **Notice:** This parameter is similar to the [global shadow filtering mode](../../../../editor2/settings/render_settings/shadows/index.md#filter_mode) (*Settings -> Render -> Shadows*), but is used for transparent objects on a per-material basis.


### Penumbra Mode


Quality mode to be used for rendering penumbra from all light sources cast on the material. This mode enables simulation of real-world shadows by keeping sharp contact shadows closer to the base and softening the farther the shadow stretches away. *Higher* quality produces *softer* shadows. Available values:

- **Disabled** - penumbra rendering is disabled, shadow edges are crisp and sharp (no shadow softness at all).
- **Low** � low quality
- **Medium** � medium quality
- **High** � high quality
- **Ultra** � ultra quality


> **Notice:** This parameter is similar to the [global shadow penumbra mode](../../../../editor2/settings/render_settings/shadows/index.md#penumbra_mode) (*Settings -> Render -> Shadows*), but is used for transparent objects on a per-material basis.


### Filter Noise


Toggles the use of noise for shadow filtering on and off. This noise is used for smoothing shadows cast on the material and reducing the stair-step effect at the edges of shadows.

![Textures](textures.png)

*Material window,Texturestab.*


#### Albedo Texture


**Albedo** texture specifies the [color of the surface](../../../../content/materials/library/mesh_base/pbr.md#albedo).


| [![](albedo_wo_texture_sm.png)](albedo_wo_texture.png) | [![](albedo_w_texture_sm.png)](albedo_w_texture.png) |
|---|---|
| *Without albedo texture* | *With albedo texture* |


The texture is 4-channeled:


1. *RGB* values store color information.
2. An *alpha (A)* value stores transparency information:

  - **White** color indicates that the area will be visible.
  - **Black** color indicates that the area will be transparent.


#### Shading Texture


**Shading** texture is a container for four different textures:


- The *R* channel stores a [metalness texture](#texture_metalness_channel).
- The *G* channel stores a [roughness texture](#texture_roughness_channel).
- The *B* channel stores a [specular texture](#texture_specular_channel).
- The *A* channel stores a [microfiber texture](#texture_microfiber_channel).


##### Metalness Texture


A **metalness** texture stores information about material's metalness:

|---|---|
| *The whole applied texture channel is white* | *The applied texture channel is partially white (reflective areas) and black (non-reflective white splashes)* |


##### Roughness Texture


A **roughness** texture stores information about material's [roughness](../../../../content/materials/library/mesh_base/pbr.md#roughness):

  - **Black** color indicates that the specular highlights are dull.


#### Microfiber Texture


**Microfiber** texture creates an effect of napped surface. The lighter the pixel, the more napped material will be.

Texture coordinates transformation parameter is an arbitrary expression ([script](../../../../code/uniginescript/index.md)) executed at run time. It is treated as a vector of four float components, consisting of two pairs of vector elements:


- Scale texture coordinates, along the X and Y axes. For example, by the scale of **2** ;**2** the texture will be repeated four times on the surface. See the second picture below.
- An offset of the texture respectively to its initial position along X and Y axes. For example, by the offset of **0.5** along the X axis the texture will be repositioned to the right (so the left edge of the texture will be rendered in the center). See the third picture below.

| *Visibility = 0.5; Visibility threshold = 1.0* | *Visibility = 1.0; Visibility threshold = 1.0* | *Visibility = 2.0; Visibility threshold = 1.0* |


##### Visibility Threshold


**Visibility threshold** influences to sharpness of the smooth transitions between the base and detail textures.


In the example below, *[Angle fade](#option_detail_angle_fade)* is set to *Object transform*.

|---|---|---|
| *Visibility threshold = 0.0; Visibility = 1.0* | *Visibility threshold = 0.5; Visibility = 1.0* | *Visibility threshold = 1.0; Visibility = 1.0* |


##### Diffuse Visibility


**Diffuse** visibility specifies the influence of the detail texture diffuse over the base texture diffuse.


In the example below, *[Detail blending](#option_detail)* is set to *Overlay*, the base diffuse texture is yellow and the detail diffuse texture is red.

|---|---|---|
| *Diffuse visibility = 0.0* | *Diffuse visibility = 0.5* | *Diffuse visibility = 1.0* |


##### Specular Visibility


**Specular** visibility specifies the influence of the detail texture specular over the base texture specular.


##### Gloss Visibility


**Gloss** visibility specifies the influence of the detail texture gloss over the base texture gloss.


In the example below, *[Detail blending](#option_detail)* is set to *Overlay*, the base texture gloss is 0.5 and the detail texture gloss is 1.0. So, increasig the gloss visibility leads increasing the resulting gloss of the material.


| ![](detail_gloss_visibility_0.png) | ![](detail_gloss_visibility_1.png) | ![](detail_gloss_visibility_2.png) |
|---|---|---|
| *Gloss visibility = 0.0* | *Gloss visibility = 0.5* | *Gloss visibility = 1.0* |


##### Normal Visibility


**Normal** visibility parameter specifies the influence of the [detail normal texture](#textures_detail) normal over the surface.


In the example below, *[Detail blending](#option_detail)* is set to *Overlay*.


| ![](detail_normal_visibility_spec_0.png) | ![](detail_normal_visibility_spec_1.png) | ![](detail_normal_visibility_spec_2.png) |
|---|---|---|
| *Normal visibility = 0.1* | *Normal visibility = 0.6* | *Normal visibility = 0.9* |


##### Detail Mask Parameters

*Detail mask parameters*


> **Notice:** The parameters is available if the *[Mask](#option_detail_mask)* option is enabled.


- **UV Transform** is detail mask [texture coordinates transformation](#texture_transform).
- **Triplanar blend** > **Notice:** The parameter is available when the *[Triplanar](#uv_detail_mask)* mapping is used to project the texture.


##### Detail Angle Fade Parameters

*Angle fade parameters*


> **Notice:** The parameters are available if the *[Angle fade](#option_detail_angle_fade)* option is enabled.


- **Fade** is a coefficient to scale the angle at which detail texture fades.
- **Threshold** influences to sharpness of the smooth transitions between the base texture and the detail texture for which the *Angle fade* option is enabled.
