Most (better) textures are made of photos and especially facial hair for males is on the texture and not part of another prop or so, so I assume that could be very useful.

However, I gotta ask - if you have painted-on hair on your skin color map - why do you bother with a realism shader at all? Why don't you just paint the whole color map yourself, SSS, specular, everything? LOL*

I'm sorry, I don't understand that, maybe because I'm from Germany and English is not my mother tounge. But I DO make all my textures myself. ??? And it is already art to get photos only to a complete 3D texture, and to provide proper bump maps and MAT settings and such for all those different applications, so somewhere there's the edge for me what I can handle, what I can understand. I have no clue about how your VSS works, otherwise I guess I would do that by myself. LOL

But I of course could provide an extra Specular Map, an extra SSS Map, Bump Map, Displacement Map, together with the texture can you imagine what Poser has to handle then for just one figure? I hoped that a shader could save us from such an extensive use of resources.
