See echo's tutorial (2 messages up) for one method of handling the upper-eyebrow material. A typical V2 head can have both an eyebrow material painted on the head, and a separate upper-eyebrow transmap and texture. Check out the Daz victoriaheadT.jpg template (or similar) to see the different locations. One alternate method to echo's and toad's methods is to use the head texture with no painted-on eyebrows (i.e. just skin) for the eyebrows, then use a texture and transmap for the upper eyebrows. It was possible in C1.1 according to an old post here (no tutorial unfortunately), so it should be even easier in C2 or 3. Let us know if it works for you.
