I have scene with one static immovable object (made from triangle mesh) and one movable object made from sphere (or spheres). When I move this sphere object and bounce to immovable triangle mesh, velocity and angular velocity of sphere object is changed. This is perfectly OK.
Now, if I want to reduce the strength of angular velocity after the impact, what should I do?
My goal is to have sphere object which can slide along mesh object without any changes in angular velocity after bouncing. Or at least somehow lower the strength of impact.
Of course I have tried roughness, elasticity, etc, but I think this is related to inertia or momentum.
