What is the best way to use curved surfaces, I'm working on a game where you drive scooter over a curved surface it's easy wavy grassy hills. What is the best way to put colliders on this type of surface, so far I'm making empty sprite and using it as tiled background so i can stretch it different way. But I feel I'm using way too much colliders in one level or not? Is there a better way? Also Is there a way I can duplicate multiple objects so they keep form because right now I have to duplicate every time then resize then place and repeat.
