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.

In Unity, is it possible to mark all colliders in a compound collider as static relative to eachother?

If I make a compound collider out of 20 sphere colliders, and I know that none of the spheres are going to move relative to eachother (i.e. the parent is going to be doing all of the moving), does Unity still keep track of all of their positions…
