I finally figured this out after weeks and weeks of being completely stumped. The issue is that on the main body texture there are RBG and a sneaky Alpha! His face needs to be applied as a separate material that essentially crosses out the weird face you are seeing.
- Create a new material or duplicate your existing body and give it a new name like… Aj_Face
- Click on the long attributes node (base color, specular, opacity etc…etc…) and under the details set this material to TRANSPARENT
- Under your BASE COLOR drag the top pin to the Base Color as you normally would
- Still under BASE COLOR drag the Alpha pin to the EMISSIVE pin
- Assign your normal as usual, Your Specular and Roughness map should be the same texture just plugged into different pins.
I am doing this all from memory, and I may be forgetting a step but let me know if this worked as I scoured the internet for almost 3 weeks trying to find a solution.
