Joe, are you sure of that? Now I'm really confused - I thought bump maps also used white for high points and black for low.

And transmaps use black for invisible and white for visible.

And masks? Aren't they white to block out (be invisible) then, in the case of eyebrows - they'd be the color of the eyebrow? Or greytones with color added in the color channel?

I think one of the examples Phil showed had both trans and masks.

I'm getting pretty confused here folks - I wish someone could make a full tutorial from start to finish on the various ways to add eyebrows...

And while I'm at it, Phils method shouls work for makeup also, right? Making it possible to have various makeups to apply without having to have the fully detailed head map each time - just switch makeup maps.

But in that case - how would one apply both an eyebrow mask/map and also a makeup mask? If they both go into the diffuse channel.. it will only accept one link, right?

Sorry to sound so inept - but I am learning so much from all this, I just need a little extra guidance. I'm actually working on something right now that, though not for V4, does involve a character with no eyebrow material zone, so this is coming in very handy. 

If I can get it all to work!
