Terrain
Reference Terrain tile.

Description

PaintContextPaintContext that contains the combined Terrain holes data for the specified region.

Remarks

BeginPaintHoles identifies all of the Terrain holes pixels that are within 
extraBorderPixels
of the bounds rectangle. The search is performed across adjacent connected Terrain tiles. The pixels are collected into a temporary render texture and stored in PaintContext.sourceRenderTexture.
After you call this function, you can write new values into PaintContext.destinationRenderTexture to modify the Terrain holes. Then, you may complete the modification by calling TerrainPaintUtility.EndPaintHoles to copy the modified data back to the Terrain tiles. Alteratively, you may cancel the modification by calling TerrainPaintUtility.ReleaseContextResources to release the RenderTexture resources.
