since for poser we a lot of times use modeled hair with transmaps it would make sense if they would make a ''fake'' specular for hair.

for example i modeled a hair prop for apollo.its impossible to get now the specular right.
like i said since 80% renders have transmapped hair it would make sense if they would make a special hair node.

for skin i would ask you something. how many layers of specular do you think is good? i am now testing some shaders of you with my changes. i read on a CG forum that skin should have at least 2 specualr layers. one on the whole body and the second for glossy effect on specific parts.
