So far I had only tested convex collision on small surfaces and terrain, but when testing on steeper obstacles, I noticed that convex collision doesn’t work, the wheel goes into the object. I need the wheel to have a precise collision with the rocks while the player climbs a hill for example, it’s a more technical offroad game, the sphere collision works well, but it exceeds too much to the sides making it useless in my situation, the line trace option with multiple line traces (9 x 3 sides) works well most of the time but I believe it must be heavy for mobile devices to handle that amount of line traces. Am I doing something wrong, is there a way to make convex collision work with steeper surfaces?
