Quote - As I mentioned, I normally have the eyebrow off (as you state) in Studio - just in this case it was on because it was actually being used for the eyebrow texture. I've worked around it by manually layering the eyebrow I wanted on SkinFace - which had no eyebrow at all. 

Are you suggesting given this that it would've worked if I'd not layered the texture but left it off? That seems pretty counter intuitive to me. :) 

I must say this level of helpfulness never failes to amaze me in the reality forums. :)

I'm not familiar with Skinface, but if you're comfortable with Photoshop or Gimp, I'd just graft your eyebrow onto the main face texture and blend the seam lines with the clone tool, then touch up what can't be fixed with the air brush in a semi-opaque spray. 

Just my experience, but when I set up face textures for custom characters, all the UV mapping for the face uses said singular face texture for everything, chin to forehead and cheek to cheek. The eyebrow never gets its own map, which is why I suspect they got rid of the eyebrow selection altogether for Genesis. 

Back to Gen4, it should be invisible on your character by default, but depending on who set the character up (especially if it wasn't done for Studio or a daz character, i.e. a poser figure), you'll see the eyebrow as a singular addition on your character which will render looking like a peach colored skin flap. 

The only thing that requries a separate map for a Gen4 character's face to really work, aside from eye maps, is an alpha map for the eyelashes.

I couldn't begin to guess your user level, but if you've not seen how reality/Lux interprets the face texture, next time you're in reality, select the face texture portion of your character in the material section and view it through the texture+uv option, within the gear menu on the far right side.

The material that the face is UV mapped to will show up looking like a wire frame mesh and semi-transparent atop the face texture.  Everything on the face tex should be there, minus cut-outs for the eyes. If your character's eyebrows are also missing, voila, there's your problem. 

If you already knew that, my apologies. New baby at home (finally!!) is killing the ol brain pan's cognitive functions.
