character falling through the terrain

Please HELP !!

Hi, I have added mesh collider to the terrain and added capsule collider to the ethan, but my character still falls through the terrain.

I haven’t used any scripts.

I have read similar topics but the problem is still not solved.

One of those objects must also have a rigid body attached to it. Attach one to your character.

Do you have Mesh Navigation? Also trees/objects need their own colliders
