I just had this thought.
You know those games when you fold a piece of paper and then one person draws a head, another the torso and so on. And then you unfold it and see what you’ve got.
Well, I thought it’d be really fun to try in Blender. You’d start with a .blend somewhat like this: http://w1.185.telia.com/~u18510119/blocks.blend so that everybody knows where the pieces should join and then each person makes his part and sends it to the others.
It might need some retouching afterwards. Maybe it’d work best with mech type characters.
I haven’t the time to try it myself at the moment, but I thought I’d test the idea on you guys.
