Can I make an object with limbs, and clone it? I've never tried this technique before. I need the limbs to update their X/Y/Z coordinates properly, so that for example: If I cloned a robot with a hand I could put a gun in the hand of the cloned robot. I don't mind if it is instanced either, so long as I have individual X/Y/Z coordinates for the hands.
What I am actually making is similar to atoms, and I need to position the electrons properly even if I rotate the atoms. I may need to scale them too, and the X/Y/Z must also adjust itself to the new scale.
