Hollow Rigidbody (Noob question?)
Hi all I'm trying to create a hollow rigidbody sphere for a 3rd person game, such as a zorbing ball or hamsterball. When my character moves, I want the ball to move too. I'm sure there's a pretty simple answer, something I'm missing, but I just can't do it? I tried making one in Blender and importing it, but no dice. Can anyone help me please? Cheers Ian
Does the object have faces on both the inside and the outside? If anything, I would recommend that you don't use a rigidbody for this- you'll get much better results if you just use a simplified, manual physics system for the ball.
If you want it to be 'hollow', making it in blender (or whatever you choose) is the only way- Unity's primitive spheres are only one-sided, and if you use a Sphere Collider (not a Mesh Collider), it will always push objects back out of itself anyway.
In any case you should avoid using Mesh Colliders with rigidbodies, since they cannot collide with other mesh colliders! This includes plane primitives and terrain meshes- which is to say, things you would usually use for floors!
