So i have a racing game with a very flat map but i find it quite boring to drive through, so i want to give it some elevation but i want the player to still be able to drive through it meaning i dont want to have angles over about 10 degrees, would using gapfill work or is there another plugin i dont know of? Or is there some way to make it work without it looking weird?
I think you should try to make some detail and props to spread around the map. Maybe have the track go through some terrain as well. This might make it seem less boring.
