I ended up sculpting 4 busts instead of 2 (middle one is just a backside of the last one), so I’m gonna mix those 4 normal maps down to 2.
The only reason I did four is for better readability of wrinkles when sculpting. The faster and more reasonable way is still to do 2 and call it a day.
Can’t get Bluefox addon to install for whatever reason, so would have to stick with the first one. Will try both later on with a fresh blender install to avoid any errors.
I have to say, “Revised mesh tension add-on” can’t be used for real time previewing. So finding alternative is a must (provided it’s faster).
