Here's a quick view of my fleshy mouth rig so far. I need to integrate the rest of my blendshapes and assign it to the controls. Pretty excited how it's coming out so far. Going to try making a UI soon.
I want to share with you a free Hard Surface Brush Pack, that was created for my personal game project called Utopia. This pack can be used along with ZBrush, Substance Painter, Quixel Suite and other software that support alpha and high maps.
