I want parts of a mesh to be bouncy(elasticity) and other parts not. when I use two materials on the same object, the game engine uses the same physics for the entire object.
Separate the object into two objects, each with their own materials. Parent them together if needed.
Just because two meshes are supposed to appear as one object, doesn’t mean that they have to be one object.
That’s what I’m planning on doing if I can’t use one object.
