I'm a little unsure and confused as to how to approach baking facial hair similar to Arthur Morgan's in Red Dead Redemption 2.
For something like the head, I know that a hair cap can be used and the hair can be baked straight to that. However, for fine stubble like above, I don't believe any additional/duplicated geometry was used...? This face texture found online looks to be a part of the overall texture...
Or was something like this perhaps projected on via paint like with ZBrush's Spotlight...?
