I've been playing with it for awhile and here's what I've done. For hair, in the color chanel, set it to Multiply. In Source 1, put the texture map for the hair. In Source 2, put the trans map. Then in the Transparency channel, set it to Subtract and put the trans map in both sources. Invert source 2. Set the "No light interaction with full transparency" and be careful with highlighting and shininess as you could make your transparent parts shiny. This works for eyelashes too. On the color channel, instead of putting in a texture map, you can just put a color in source 1 if you'd rather. As for eyes, you don't need to get rid of the materials. Find the one that corresponds to the eyeball (the fully transparent part in Poser). Set the color to Value with 0%. Then set your highlight, shiny, transparent, refraction and reflection. I got this by looking at Carrera's default shader for glass. Once this part's transparent, you can play with the eyeballs, irises and pupils as you like. I got this technique here and a tutorial was on a japanese site. Sorry, can't find the link. hope it helps. This is definitely the most frustrating part of Carrera for me. That, and it seems Poser figures take up a TON of Carrera space. Just tried to load a Vicky figure with the new Cleo Hair and it never would load! and I've got a 1.4 Athlon with 512 RAM!
