Here is a clip of my caveman model showing off some of its blend shapes (morphing expressions).
Basically, this test shows that all of the input connections are working. The teeth are temporary as is the skin color and the eyes.
Now that the model is working, I'll start laying out the UVs in preparation for painting and displacement maps. The UVs will also be used to lay out the hair. Speaking of displacement maps; I've learned a cool technique to create dynamic displacements that change as the expression on the character's face changes. Things are going well with this model so, hopefully, I'll be able to wrap this up in a week or so...
