How to add HSV color transformation to skin shaders

colcurve

Hi, is there a way to add shader parameter/brick  to tweak the diffuse color map, by converting it to HSV, modify the channels, and convert back to RGB?

Like in Poser's EZSkin. So one can make the skin a bit brighter or darker or play with the hue.

(I do not want to multiply the map with a fixed color.)

Thanks!

i just found this. so someone got it work by adding lots of shader nodes.

maybe there exists a more compact brick to achieve the same?

What are you trying to do? And in what engine?

I find that different artists use different skin shader settings, which leads to inconsistent output under identical lighting conditions. A common shader system helps to even it all out.

Now, if a specific skin is too dark or too light, it might not even be the Diffuse channel. In Daz Iray, the Translucency settings are the cause of a lot of the variance between different vendors.

Dropping Translucency weight, changing the Translucency Color, changing the tone of the Translucency maps... these do a lot in changing how a skin looks.

I scripted it in my Amazing skins products. You can end up with one single brick to control HSV if you script it in the shader builder. Limited to 3delight, the equivalent for Iray is much more complex to achieve. In Iray this is recommended to use the translucency settings to change the hue.
