A while back I saw a post someone had made of a dwarf character they'd made using only boxes. It looked really cool, and the boxes didn't deform at all. I need to make some mechanical characters for a class, and I figured that I could use that concept to make them quickly. However, I can't google it without getting box…
Correct. It is CAT. I believe the dwarf rig you are talking about is by Daniel Marsh, aka polycount's very own @dannyannymation. IF he didn't make it, he at least animated it. I first saw this anim on polycount. Maybe he can give more insight. Also, when researching how to do it in a non-CAT way, try looking for Proxy Rig…
Hey Snickerwicket! The dwarf rig I made that you liked is indeed created in 3DS Max using the CAT system plus a few extra little meshes thrown in. Its a great way to quickly throw an idea together and start working without having to worry about a model.
You can make a box character a number of ways. You can group the boxes and constrain that group to a joint (such as an arm or spine joint), or you could smooth bind a box mesh directly to a single joint. I'd recommend constraining, as it would likely make the rig faster, and since you constrained the group, you can swap…
