I get pretty good results for sweaty-looking skin with a Glossy node attached to Alternate Specular in the P7 Material Room with Firefly ray-tracing. Thanks, bagginsbill.

However, I have found that I have to include and tweak a Bump for the skin texture, so that the specular reflections have rough, irregular edges. Without the Bump, the specular reflections are rounded, contiguous areas with smooth edges, and this makes the skin look like smooth plastic.

The trouble is that if I increase the Bump value enough to make specular reflection rough-edged, to about 0.01, the skin looks like it has the texture of orange peel.

I've also played with the Roughness and Sharpness values in the Glossy node, but the results seem dependent on the Bump map. I've also tried attaching a Blender node with Glossy and Noise, but the reflections are still smooth-edged. So, finally, my question: Is there a way to mix a bump or noise channel into the Glossy node so that a Bump map isn't needed?

Thanks,
Rick
