Multiple Colliders

Questions & Answers
1

I tried to use multiple colliders for my character. I used capsule collider, and collider was attached to each part of the character. One capsule collider for hand, one for foot, one for head, one for shoulder, like this. Each collider was attached to different objects.

Then I wanted to move character physically, so I tried to use rigidbody for the character. And there is a problem. Do I have to attach rigidbody to all objects that have a collider? Colliders are attached to different objects, so I can’t use rigidbody for only one object. I think it isn’t good way to do that due to the performance. Is there a way to use multiple colliders while using rigidbody as a minimum?

I would attach a rigidbody on a parent object that doesn’t have any collider and then all the objects with colliders should be children of that object.
I have done this before with lots of colliders
the collision detection wasn’t as much a problem for performance as all the rendering.
