I almost always include an HSV node in every shader I've ever produced. But, I've observed it to be a significant slowdown. Remember ice-boy noting that this shader is sooo much faster than my AMUCFS shader? Part of that is because I stripped out all the non-essential stuff to make it faster - and HSV got the boot!
You can easily add an HSV node into the skin shader. However, let's try something simpler first. It may be that for the particular situation you've got, the SSS is just too strong, making it more reddish than you want. Try decreasing the SSS multiplier.
That would be arrow #1 in the screen shot below. The default value is .7. Making that a lower number will decrease the redness.
Are you using the PR2 prop? Remember that I had a blue tint to that one that actually makes the skin less saturated (because it is starting off with too much red.) The above screenshot is of the PR1 skin shader. The PR2 doesn't have the blue tint. Jessi's texture is very very red. Try putting that blue tint back (Arrow #3)
If you find those adjustments are not sufficient, or perhaps not friendly, I can add in the HSV as an optional skin shader which you can load at your desire.
Everybody should realize, too, that this is preview release stuff - I have not yet added in all the parameter knobs. When I get this finished, you won't ever have to go into the shader nodes. You can just spin knobs on the figure's parameters to adjust these various shader characteristics.
Have you played with Parmatic ever? Parmatic was a plugin I put out a long time ago that allows shader parameters for dozens of zones to be controlled by a single dial on the figure.
Parmatic will be merged into VSS, so that dial technology will be available to configure VSS shaders. You'll be able to put the dials on your VSS prop OR on the figure. That way you can have per-figure parameters, but not have to change them in all the zones.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
