I have Kinematic Rigidbody and Character Controller colliding. When moving the controller against the rigidbody at certain angles the Character Controller goes on top of the Rigidbody collider using it like a step. Changing the step offset or the rigidbody size have 0 effect. Why is that ?
Can you supply pictures to show what your setup is like? “Moving against object at certain angles” could mean a myriad of scenarios. 
I think I understand what you mean, but actually seeing what you’re seeing would alleviate many misunderstandings.
