terrain + mesh + mesh collider doesn't work?

Questions & Answers
1

So, I imported an fbx of a cone and when i add a mesh collider and a rigidbody to it, it falls through the terrain! I have a collider on the terrain as well. I tested both the mesh collider from the cone and the terrain collider with a unity cube. So basically, the cone collides with anything that isn’t the terrain. And the terrain only collides with cubes/spheres ect. from unity. Anyone know what i should do?

From the Unity Documentation:

There are some limitations when using the Mesh Collider. Usually, two Mesh Colliders cannot collide with each other. All Mesh Colliders can collide with any primitive Collider. If your mesh is marked as Convex, then it can collide with other Mesh Colliders.

Marking mesh collider as convex solves that problem. Thanks!
