To Reference or Not To Reference

What is referencing, and when should animators use it? File referencing ("referencing", for short) is the process in Autodesk Maya which allows the animator to make changes to an animation rig in the course of production and have the new rig automatically update itself to all your existing animation files. It's pretty much what most studios use to manage their animation pipeline, one way or another, as most production rigs are a work in progress.

The question for animators working and studying from home is, should you import the rig directly into your shot, or should you use referencing? Here are the pros and cons.
