| terrainDest | Function returning the RenderTexture to be written for each Terrain. |
| blitMaterial | The material used to copy the data. If null, the default blit material is used. |
| blitPass | The material pass used to copy the data. Its default value is 0. |
| beforeBlit | An optional action to call before copying to each Terrain. |
| afterBlit | An optional action to call after copying to each Terrain. |
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.
