Clothing a character in Blitz3d?

Thanks. So basically the clothes have to be animated with the same bones that are driving the rest of the body? Is there a way to make sure that the body underneath doesn't poke through the clothing?

Also, how do I choose which layer to render a mesh to and hide said layer? I'm a bit new for Blitz3d. I have Blitzmax experience, but right now I'm evaluating the Blitz3d SDK.
