Exercise ultimate control over your 3D objects
In basic use, this tag works in conjunction with the Tweak mode to determine if objects can be moved without first being selected, and gives you control over object highlighting.
Use dynamic proxies to interactively adjust other objects based on the polygon selection you click to tweak. Particularly helpful for tasks like character rigging, the Interaction tag also reports all mouse interaction, including the polygon clicked, and allows controlling objects through XPresso, C.O.F.F.E.E. or Python.
