# Texture Streaming

A summarised guide on the concepts of texture streaming, increasing the texture streaming pool size and disabling texture streaming.

## Texture Streaming
* This denotes the detail of the textures which are to be viewed.

* Texture streaming is responsible for handling the transition between different mipmaps as the camera distance is changed.

* As the camera moves closer to the texture, the texture streaming pool will become more full due to the larger mipmaps being streamed.
   
## Increasing Texture Streaming Pool Size
* Warnings may arise when attempting to render extremely high detail textures within the scene. This is typically common in ArchViz projects.

* This can be mitigated by increasing the texture streaming pool size in two ways.

* The first method entails using the *Console*, which can be opened with the **tilde** key, with the command:
	```cpp
	r.Streaming.PoolSize = [DesiredSizeInMB]
	```
        
* The second method entails editing the **DefaultEngine.ini** file which is a more permanent solution if the issue is reoccurring. Within the file locate the **[/Script/Engine.RendererSettings]** section and add the line:
	```cpp
	r.Streaming.PoolSize = [DesiredSizeInMB]
	```

## Disabling Texture Streaming
* This is useful when the highest resolution texture is desired at any given camera distance. 

* This will severely impact performance if applied to all project textures.

* Applicable cases generally include UI elements and text containing textures which the user is required to read with clarity.

* Within the texture viewer window, **enable** the **Never Stream** parameter under the **Texture** section of the *Details* pane.
