I'm having trouble getting clean transmapped hair and eyebrows (manual import from Poser) working properly. I am hoping this is a legacy issue with C3 on Mac OS-9 and will go away when I migrate and upgrade. The closest to clean effect I get is using the transmap straight from Runtime (jpeg format), clicking "invert image" and "no light interactions when fully transparent" as well as, in the render settings, "light through transparency." In the materials room previews there is still a halo of white that will not go away, though, and there is still a bit of that visibility going on in the final render with everything switched on (aka GI and full raytracing). Playing with the texture map within Carrara, using for instance Shader Ops, merely makes the visible fringe more visible; brightening the map actually makes the invisible portions translucent white, and darkening the map turns the invisible parts dark. Playing with the map outside in PhotoShop, trying to make sure it is fully white and black, also appears to have no real effect. Is this at all familiar, and am I correct in hoping that it will go away when I upgrade?
