Download a base character model on daz studio, I’m using 8th gen. Go into zbrush and sculpt it, focusing on modifying the face, I want a more cartoony effect. One level of subdivision to adjust large, three levels of subdivision to adjust details.
Note that even if the face is cartoonish it should follow the base face. Here’s a note documenting the qualities of the key features, the mouth, nose and eyes.
Go into blender and look at the character wiring, make sure the wiring makes sense after modifying the face so that I can follow up with animation later. Also, perspective is different in zb and blender, I use blender as a baseline and iterate in zb until I’m satisfied.
