    First, you can see the bug in action here:


    When rigidbody objects are falling from high position (300 in my test), the ground collision doesn't works, the objects falls through ground.

    As you can see in the video, when I change the height to 30, it works.

    The spheres have rigidbodies using gravity and a sphere collider. For info, the grounds have mesh collider for the two on the right, and a box collider for the one on the left.

    I've tried to add kinematics rigidbodies to the grounds but it doesn't changes anything.

    Using Unity 2020.3.28f1.

    You can find a minimal reproduction here: https://github.com/BenDevelopment/Unity-3D-gravity-collision-bug

    Any idea why the collision behave like this?

    Sorry, what doesn't it change? If you have a problem and this doesn't solve your issue then it's not the same problem. Please create your own thread and describe your problem rather than necroing a thread like this.

    Thanks.
