Hello,

Following a change of material I have reformat my pc and just reinstall and since I have the following error in the Editor:




I can not find where does the error, please help me please

Sounds like it thinks your character has a physics body other than a capsule associated with it! The Character Controller can only work with capsules.

I'd check your character physics settings in the Editor first and see what it thinks the physics body is.

I solved my problem it was just a horse that will take in a dinosaur
