Hi, I've been trying to make a platforming character controller using the new Physics, and got some extremely weird bump up/bump back when walking on anything else than BoxCollider or SphereCollider. I made a minimal scene reproducing this behavior. With the default Box, the sphere travel smoothly as expected. With the default Plane, the sphere will get randomly bumped upward. Is this somehow the intended behavior, and if so, what are you supposed to do to make your characters walking smoothly and predictably ? Or is it an actual bug ? This happen both on Unity 2019.3.13 and .3.14.
