Mesh Collider for a complicated mesh?

So I’m making a game where you fly in a spaceship and can go to randomly generated planets. These planets have hills, and I want to be able to come into contact with them, but the mesh for the planet is too large to use with a mesh collider. Does anyone know the best way to go about this?

Well, it turns out I was doing the complete wrong thing. Apparently, I didn’t need a rigidbody. Now I feel silly. :stuck_out_tongue:
