Why does my capsule collider’s radius have to be smaller than the height? I want to make something really wide, but short and whenever I try to make the radius bigger than the height, the height is reverted to the same size as the radius. How can I make a short, but wide capsule collider?
Another one, as I just found related to, why can’t I have 2 capsule colldiers on the same prefab?
You can assign a different Direction to the capsule collider, and you can also have as many colliders as you like in the same object (not sure if this is a feature of 4.6 or lower).
You could place several sphere colliders as children of the main object in a circle arrangement. The main object(parent) should have the rigidbody on it(none of the child colliders should have rigidbodys on them!). The parent rigidbody will then treat all the child colliders as one. This is called compound colliders, see this link for more info(about half way down the page) :
Draw a capsule collider by hand. It will be obvious why you can’t make it wider then it is high.
By definition a capsule collider is a cylinder with two semi spheres on it. The smallest height this can go to is the width.
