Thanks, I’ve skimmed through it the other day and most of it is too complex for me.
Plus, he seems to be doing it via displacement textures driven by masks (that are also driven by tension maps?).
I plan to just use regular normal maps, controlled by dynamic vertex colours.
I did, however, save this for future reference.
Meanwhile I rigged the face (the best I could) and posed it in two exaggerated states for wrinkle sculpting.
These are the areas I figured need wrinkles:
Red (“surprised”): forehead, lips and around mouth, chin folds, upper eyelid stretch
Green (“angry”): furled brow and nose, nasolabial fold, mouth corners, lower eyelid, crow’s feet, cheek folds (dimples?).
