We're liking
this Leopard Rig by Truong, available for
free download at Gumroad. It is an attractive, well-structured rig with simple controls, and it's pretty easy to figure out how to use it.
In order to get real-time playback in your viewport in Maya, you need to
go into your Animation Preferences (bottom right hand corner of the
screen) and then under Settings/Animation/Evaluation change Evaluation
Mode to Parallel.
So, how do students get the most out of this rig?
