View Full Version : Question about skin reflectivity

Hello,
I am looking for tips on creating realistic skin reflectivity (ie. wet lips, shinny skin around eyes etc).
I have a scene with a HDRI setup and this HDRI map is raytraced
onto the skin, which has a reflectivity (specularity) map (I put this in the specular roll off in Maya as it seems to affect reflection in Maya...weird). I have no maps in the reflectivity and reflected color in the shader.
I am also using facing ratio (this is incidence angle in Lw I think) so that skin is less reflective where it faces the camera directly.
Using this I am having trouble getting the wet look in the lips and around the eye which mostly face the camera.

Any tips on this? Is this a good approach at all?

Thanks

Can you mask off the "facing ratio" so it doesn't interfere with the lips/etc.?

Maybe just add a slight reflectivity to those areas.

Post an example?

I wish I knew how to mask off facing ratio with a map in Maya. Maybe someone knows?

I'll post a render later...

I'm assuming you're passing the facing ratio to the U or V coord of a ramp. If not, let me know.

The way you would mask the lips off would be to toss the ramp in on the bottom of a layer texture, and put another texture on top with an alpha chanel.

I would think that the eyes could simply be a separtate material. Correct me if I'm wrong in this case. (-:
