パラメーター

terrain Reference Terrain tile.
inputLayer Selects the alphamap to paint.
boundsInTerrainSpace The region in terrain space to edit.
extraBorderPixels Number of extra border pixels required.

戻り値

PaintContext PaintContext containing the combined alphamap data for the specified region.

説明

Helper function to set up a PaintContext for modifying the alphamap of one or more Terrain tiles.

BeginPaintTexture identifies that alphamap 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 calling this function, you may modify the alphamap by writing the new values into PaintContext.destinationRenderTexture. Then, you may complete the modification by calling TerrainPaintUtility.EndPaintHeightmap 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.
