Can't stop gameobject (imported obj file) from falling through the terrain

Can someone please advise me how to stop my character falling through the terrain?

The character is an imported obj file and once I add a rigidbody component, he falls right through the terrain.

 

Two rigidbodys with concave(non-convex) mesh colliders cant interact.

You dont put a mesh collider on the terrain, theres already a terrain collider there(a terrain collider is a special mesh collider optimized to work with the terrain system)

Also, most of the time having a mesh collider on the player is just overkill.

 

Thanks for the reply. But not sure what do I need to change to get it to work?

Bear in mind that I'm a complete beginner so apologies for the basicness of my knowledge!

 

1) remove the mesh collider from the terrain
2) either make the player collider a primitive(box, capsule, any thing that's not a mesh collider) or mark it as convex
3) profit/come back to troubleshoot some more

 

worked! Thank you!!!
