Just curious is it possible to rig a model that i modeled using a rig from another a rig that was created for a different character? the reason im asking this question is, i can model my own characters but i dont wana spend time rigging especially human characters they all have 2 legs 2 arms even though they may vary in size and hight
Eh... you can do it, but you'll have mixed results. The more different the models are, the less successful the rig will be.
Shrek and Pinocchio both have two arms and two legs, but the rigs for them have to function completely differently, you know? The way their limbs move and flesh bulges and folds (if it exists) will be specific to a character, not too easily transferred across models.
