public void DirtyTextureRegion(string textureName, RectInt region, bool allowDelayedCPUSync)

Parameters

textureName

string
The name of the Terrain texture.

region

RectInt
The rectangular region to mark as dirty.

allowDelayedCPUSync

bool
Specifies whether to allow delayed CPU synchronization of the texture.

Remarks

Use this function only after you manually change the GPU part of the Terrain texture, such as by using Graphics.CopyTexture. Set the 
allowDelayedCPUSync
parameter to 
true
if you want Unity to perform immediate synchronization of the CPU part. If you set it to 
false
, Unity queues the reading back of the dirty region until the next call to TerrainData.SyncTexture.
If the current active RenderTexture contains your changes, and you want to copy a part of it into the Terrain texture, use TerrainData.CopyActiveRenderTextureToTexture instead.
