Bad eyebrows for M4 in Iray

I've come accross an annomally I can't seem to figure out how to fix. No clue what's going on or what settings to change. I've tried a variety of settings both in the surface as well as in the render engine but can't get it to go away.
It's a simple m4 tried using the m4smple_face texture as well as the m4hi_face and it happens on both textures. Tried using the native 3delight settings as well as converting to iray and it appears on both. The textures are fine from what I see in photoshop...
Has anyone come across this and/or know how to fix it?

I think I'm close to a solution as I was just going through teh texture areas on the figure again and saw that there was no texture set for the seperate "eyebrows" portion...
Wasn't really sure what to do so I put the face in there as well (since it had the eyebrows painted on) and the black circles went away, but still didn't line up quite right.
Guess maybe I should reset the textures and start again.
Open your favorite image editor and create a new 512 x 512 pixel image. Set it to greyscale and file with pure black. Save as jpg or png. Then apply that to the Cutout Opacity channel for the separate 'eyebrows' item.
hear that?
that's the sound of my hand slapping my forehead! I can't believe I didn't think of just hiding the unneccessary surface.
Doh!
Thank you :)
The reason why I like making the opacity map...you can use it for other things with a few brush strokes. Want to add a bindi to V3...paint a white circle on the map, set the color and instant bindi.
Well apparently I had this backwards. The eyebrows load by default completely invisible, so it's when I make them not invisible that the black circles go away
Ok, I figured out the problem and fixed it. It's the same glitch that sometimes pops up with the eyelashes. When I realized it was the light passing through the transparency I parented everything to M4 and moved M4 to 0,0,0 and he rendered correctly.
Please note the version of D|S you are using. The issue with bad transmap rendering when not at 0,0,0 is known in 4.8. It would be nice to know whether it's fixed in 4.9.
Sorry, I've not updated to 4.9 yet and had been messing with this issue for a few days now before 4.9 when live so I assumed...
Anyways, eventually I will update to 4.9 I think and will test out the issue and see if it's present in 4.9 and repost here (I have a saved scene somewhere that had the same issue but I couldn't fix it so I just repositioned the face so it wasn't as obvious)
