Hi everybody, I'm using maya6 and mental ray to texture human skin to a poly human head. No programming experience, but studying; now connecting mr nodes within maya GUI. Trying to achive sub-surface-scattering I used a diffusion shader( download it at https://animus.brinkster.net/stuff/stuff.asp), very good shader, and connected several mental ray factory nodes.I lit the scene using two directional lights and a hdri mapped to ambient attr of lambert shader attached to sphere soroundig scenario.Also connected the same hdri to environment material in mental ray section of SG.preety nice for a begining.You can find first images at https://www.geocities.com/bernardoalo.../3dImages.html ,hope I've included enough to explain problem, sorry for the format, temporary site. Once I finished the first tree, I decided to build a phenomenom, to simplify future texturings, just exposing attributes I'd like to modify.The point is that, when I rendered, using the new-phenomenom-shader, results were different, as if some environment-final gather were missing, or don't know what.I tried different ways while creating phenomenom-.mi file, but always the same.
I'd thank any suggestion, bye
