I downloaded the free unity store asset base male (link below). In unity I created a Plane and then imported the asset and tick the box to create colliders and applied the settings (made humanoid). I dragged into on the plane and applied a rigid body and it fell through. I then added a mesh collider and ensured the mesh for the male applied to the mesh collider. Still the character fell through - please note that the mesh was NOT aligned to the character - it was offset.
I then added a character controller - the character did NOT fall through.
Can someone please tell what I am doing wrong? I have a character, applied the mesh, even generated the initial mesh and still the character falls through. The only thing that makes it stay up are box, cylinder colliders and character colliders.
I downloaded several other characters and they all have the same issue.
I simply cant get my head around this at the moment. Some help would really help get this issue sorted out.
I think that the underlying problem is the RigidBody on the plane. Try removing it. Generally the “ground” just needs a collider. Also try using a Cube instead or changing the plane to use a BoxCollider. The collider is not the problem, but a Box collider is cheaper than a MeshCollider (even for a plane.)
If I mis-read your post and the Plane doesn’t have a RigidBody, then disregard
