I am making a map and I have laid out a race track and made the road a DecalRoad. I have outlined this track in grass and added sand traps at the end of tight corners. When I am driving a car on the road, it feels like the car is on sand or grass. After removing the decal I realised that I had painted the terrain underneath the decal road with grass and sand to the preferred asphalt. Is there a way to quickly and easily paint all the terrain underneath the decals only? (I know I could manually do this but I was wondering if there was a quicker way) Pictures to show what I am running into: (With road on terrain) (Without road on terrain)
