Here’s a nice animation rig that’s lightweight and loaded with features.
A fully articulate face – exchangeable hair, glasses, articulate tongue and a robust mouth shape system. You’ve got IK FK spine, arms and legs, optional shirt with animation controls, breath and a few more neat features, along with the standard animation rig.
Check the readme file for additional details, it is straightforward, “plug and play” for any animator
It comes with a simple shader setup but it’s UV unwrapped to suit your own texturing needs – what else can I say, I’m fond of this rig and I think you’ll find it easy and versatile.
