Would it be better to use vertex groups or multiple objects to rig a robot consisting of various parts?
I’ve done it both ways. The only real difference is in how you select the parts while you’re attaching them to bones. It really amounts to the same thing, just that you’re doing it on an object level if the parts are all discrete objects… and you’re doing it on the vertex level if it’s all one object.
Having multiple objects—or just a single object—attached to your armature makes no difference when it comes time to link it into a scene.
All that to say: whichever way suits you will work.
Hey, I second what Sackadoo said, but its really going to be determined by how you modelled and set-up your parts, and if you plan to exploit any of that, ie, stretchy metal parts.
Thanks I appreciate the support
