How do I make a compound rigid body?

I would like to make a compound rigid body so that I can use several simple bounding boxes to define a more complex mesh. How do I parent/constrain the multiple rigid bodies together? There are no hinges, I just want to make the multiple simple bodies behave as one complex rigid body.

Also, is there a way to see a visual preview of the current collision bounds? I would like to see my cylinder/capsule alignment to make sure it is doing what I want.

I’m surprised nobody commented on this. You can use the Compound button - I’m trying to get the hang of it myself, but it’s fairly simple. Set child objects to be Static Ghosts with their collision bounds set the way you want, and Compound checked. The Compound setting may also have to be checked on the parent, but I’m not sure.

EDIT: I’m sorry, I thought this was concerning the game engine.
