Character Controller Falling Through Floor

I m using the official unity tutorial.

Character controller falling through floor.

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. However my object falls through the floor. I attached a camera to my controller and i can see that it falls past the ground and continues to fall into infinity.

Over the last week i have been switching over to bullet physics from physx. 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. Please do not put a rigidbody on a charactercontroller. Character controllers are not meant to be used with a rigidbody.

From the unity docs. I know that i need to detect the colli. The character controller is mainly used for third person or first person player control that does not make use of rigidbody physics. 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.

I want to make a bouncing ball effect. It keeps falling through the floor. In the details section for your player character mesh see if you have the box simulate physics checked or not.
