Blue man, what did you end up doing? I’ve been trying to figure out how to rewind, or save/clone a physx scene, or create a new scene that only contains actors, forces, and constraints in a certain area.
I was going to try to set only the server to fixed timestep, and have the clients maintain an old scene. When a client receives position updates with a timestamp attached to it, it takes the old scene and simulates forward until it hits the sent informations timestamp, then updates the positions of the objects in the old scene, and then simulates forward again. But I’ll admit this is far outside my area of experience, so I don’t know if that’d work.
