public void Scatter(Func<ITerrainInfo,RenderTexture> terrainDest, Material blitMaterial, int blitPass, Action<ITerrainInfo> beforeBlit, Action<ITerrainInfo> afterBlit);

Parameters

terrainDestFunction returning the RenderTexture to be written for each Terrain.
blitMaterialThe material used to copy the data. If null, the default blit material is used.
blitPassThe material pass used to copy the data. Its default value is 0.
beforeBlitAn optional action to call before copying to each Terrain.
afterBlitAn optional action to call after copying to each Terrain.

Description

Applies an edited PaintContext by copying modifications back to user-specified RenderTextures for the source Terrain tiles.

After the edits to a PaintContext are complete, this function applies the modified data in destinationRenderTexture to the data stored for each Terrain. Scatter performs this copy to a set of RenderTextures, which is specified by terrainDest.

This function uses the following steps to scatter to each Terrain in the PaintContext:
1) Calls terrainDest to retrieve the target RenderTexture.
2) Calls beforeBlit.
3) Uses blitMaterial and blitPass to copy the destinationRenderTexture into the target RenderTexture.
4) Calls afterBlit.
