Is it better to use the Plane Mesh Collider or a Box Collider for Walls and Floors.

I noticed that the Plane has a Mesh Collider and the Cube has a Box Collider. I’m wondering if a simple Plane type Mesh Collide would be as efficient or more efficient than a Box Collider for floors and one sided walls? Does anybody know?

A box collider is calculated as a collision volume, whereas mesh colliders check their bounds first, then run a per-triangle collision (on reduced triangle meshes generated by the engine, but still). So, typically, it’s better to do the box colliders.

However, if you’re doing a whole level, one mesh collider is probably better than a hundred box colliders, so it’s a give and take.
