Colliders Comparison

[skippy224]

Is there a reason primitive shape (Capsule and Sphere) colliders are used on the asteroids instead of using the mesh collider/convex for each asteroid?

Thanks.

Because they are very expensive, unless you have a very small scene,
you wanna avoid mesh/convex colliders. Probably even then.

Here is someone who does a comparison;

Rusty has hit this one squarely on the head. Whenever possible, we want to avoid complex collision logic. You can use the mesh colliders if you wish, but as the number of elements in your scene increases, the more time the Physics system will spend performing the calculations to determine collissions.
