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

string

The name of the Terrain texture.

RectInt

The rectangular region to mark as dirty.

bool

Specifies whether to allow delayed CPU synchronization of the texture.

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.
