A Mesh Collider allows you to perform collision detection between meshes and primitives.

A Mesh Collider allows you to perform collision detection between meshes and primitives.

The Mesh Collider takes a Mesh Asset and builds its Collider based on that Mesh. It is far more accurate for collision detection than using primitives for complicated Meshes. Mesh Colliders that are marked as Convex can collide with other Mesh Colliders.
