A propos des effets spéciaux sur Benjamin Button :

We were able to grab performance pieces, and nuances from Brad. That then we were able to build into a rig ; a rig being an armature that you can pull on to and control how the face moves. A rig is really just whatever mechanism you’re gonna use to make a static piece of geometry move over time. That rig then allows us to build all of Brad’s… the way he moves his face, the way he emotes, you know, his expressions…

Existe-t-il un terme technique pour traduire "rig" dans ce contexte ? équipement ? installation ? ça m'a l'air plus précis que ça, tout de même. Merci pour votre aide.
