About physics materials

Hi,

my understanding is that a physics material has a bounciness value and usually you will have a rigidbody which has one collider with one physics material attached to it.

But suppose you want to make a billiards game. A ball should have 80% bounciness with the cushion but 100% bounciness with other balls. How do you realize that?

If two balls with different physics materials collide (one bounciness x, other bounciness y), how does Unity compute the resulting bounciness?

Sorry! I just found the answer in Unity - Manual: Physic Material asset reference. It will probably be the bounce combine property of the physics material. Sometimes writing a question down does most of the job.

The documentation is still unclear about what happens when the two physic materials have different combine modes. The only answer I’ve found about that is here - Physic Material Friction Combine Mode lack of documentation? - Questions & Answers - Unity Discussions
