Why doesn’t the mesh collider collide smoothly the same way the sphere collider does?
I filmed the difference [1st. is sphere, 2ns. is mesh and you can see my Burger shaking after it touches the coins; don’t mind the dead tree collision plz]: Here
Mesh colliders are an order of magnitude more effort to calculate collisions with than primitive colliders, and obviously the collisions appear much rougher because the angles and geometry are far more complex.
Inevitably when mesh colliders are involved, the answer usually boils down to “do you actually need to use a mesh collider”? And if you do, then you should use it for only specific collisions (like being hit by bullets) and not ALL collisions (like running into walls).
Shaking after hitting the coins is odd though- are your coins not triggers for some reason? A trigger shouldn’t have a physical effect on a collider in that manner, so either the shaking is not related to the coins, or you can fix it just by turning the coin colliders into triggers instead. Either way though, I wouldn’t use a mesh collider for the burger- capsules are usually the best bet if you want smooth collisions with an object that’s wide or tall.
