    Hello.
    I try to create a physics simulation environment in Unity.
    But, when I roll my object from the top of the hill, my object deviates from the expected course.
    My object has sixteen spheres collider on the tip of the foot.
    And, these colliders' position is calculated accurately.
    Please tell me the solution to this problem.

    There's absolutely no way anyone can help you with so little information. If you don't put effort into describing the problem, nobody can put effort into helping you.

    At best, it's unclear what the problem is so we have to guess.

    The only thing I can guess is that you expect it to roll as if it were a cylinder rolling which of course it's not, it's only (presumably) an approximation so with spheres on those spikes(?) so it'll only approximately roll.

    Looks like it'd be better being a CapsuleCollider. Of course, it all depends on if it's only interacting with the terrain.

    Alternately, just spheres on the ends of it. The obvious problem is that it'll collide with stuff outside of what you can see (the ends).
