Character Controller Falling Through Floor

It keeps falling through the floor.

Character controller falling through floor.

How to stop falling through floors and colliders in unity recently i have been working on a 2d platformer which uses the inbuilt unity physics and rigidbodies. One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders. Over the last week i have been switching over to bullet physics from physx. When i use the character manager to build a character using a model from mixamo including but not limited to characters created in fuse the character immediately falls through the floor when i press play.

However my object falls through the floor. Character controllers are not meant to be used with a rigidbody. I m using the official unity tutorial. Please do not put a rigidbody on a charactercontroller.

While i cannot explain to you why exactly i do know that when fiddling around with physics stuff in the templates i would be able to play a level fine and then upon changing the value of that checkbox for either the floor or character mesh i was falling through the floor. The character controller is mainly used for third person or first person player control that does not make use of rigidbody physics. I attached a camera to my controller and i can see that it falls past the ground and continues to fall into infinity. I 39 ve gotten everything to work except my character controller.

On the object i added a rigidbody and it already has a box collider. I want to make a bouncing ball effect. From the unity docs.
