Hi,
I made a ellipsode body to the camera, and when I controlled it, if it rush into some edge, for example, the edge of a stair's step, it will pop up and then drop by the gravity, just as a elastic ball. I have set all the friction, softness and elasticity to zero, but the problem still remain. How can I solve that?
