    Hi,
    does anyone know a solution (or the right settings) for two rigidbodies, one on a client, one on a server?
    If I enter my car and make the car a player object, I can drive it and it gets syncronized like it should.
    But if I hit another one, they ignore collisions until the next sync and then jump in the air, since they are half overlapping.
    If I put both on the server, I can't drive them anymore.

    why do they ignore collisions? nothing in the networking would make them do that.

    In frames, 60 FPS, 30 updates per second:
    1. Client sends position A, just before collision
    2. Client sends nothing, collides with other car
    3. Client sends position B, after collision. Server updates the client object and they are suddenly overlapping. Physics get calculated and they explode from another


    Edit: oh my god, I'm so sorry. One of the colliders was on the wrong layer.
