I'm experimenting with modifying terrain in-game with TerrainPaintUtility in the Experimental.TerrainAPI. Basically I'm calling TerrainPaintUtility.BeginPaintHeightmap, blit the modification into the paintContext's destinationRenderTexture and then call TerrainPaintUtility.EndPaintHeightmap. This works great in preview mode but doesn't work in an actual build. I've tried calling SyncHeightmap on the corresponding terrainData afterwards but that didn't do the trick. What additional steps are required to get this working in the game build, or are these methods only intended for use in the editor? Thanks!
