# landscape_terrain_base


The *landscape_terrain_base* material is a default material for [Landscape Terrain](../../../../objects/objects/terrain/landscape_terrain/index.md) objects. Via this material, you can manage different options for terrain optimization and control the post processing for terrains.


Terrain textures are assigned via the [landscape_terrain_detail_base](../../../../content/materials/library/landscape_terrain_detail_base/index.md) material used by [Landscape Layer Maps](../../../../objects/objects/terrain/landscape_terrain/landscape_layer_map.md).


To adjust the landscape_terrain_base material, open the Surfaces tab of the Parameters window:
