Quote - @hairydalek:  I understand what you are implying.  I also had the same problem with the LK-Lyra texture for V4 by lkiilerich.  This vendor uses node shaders for the skin texturing so essentially I'm replacing one set of nodes for another.  I don't know which version of Poser you are using but I'm going to assume you are using PoserPro.  The reasoning is that what you are encountering is actually over gamma correction applied both the VSS nodes and the Poser render settings. 

Hopefully I'm doing this correctly, the included image are renders performed with IBL white @ 20% accompanied with 1 White Spot Light @ 40 % Intensity.  Left image is the base texture, center is rendered with VSS, Gamma Correction 2.2, and right image rendered with VSS, Gamma Correction 1.  As you can see, the center image is somewhat acceptable but has an overall gray appearance and is considerably lighter than it's counterpart on the left.

By going into the material room and changing the GC from 2.2 to 1.0, not only do you restore the skin textue but you improve the quality of the render.

Hi,
yes - it was Gamma. Thanks for the post.

I thought of this very late last night, but didn’t post until I had tried it out this morning. I had forgotten that this was in the VSS as well. Gamma Correction seems to be everywhere. So I had Gamme in the render AND the shaders, which of course made a right pig’s ear of the whole thing. Now that Gamme is back to 1 in the shaders, I’m getting what I expect. Phew!

There’s a lot of information here, and I was trawling this thread for clues about tinting textures - GC was not in my mind at that point.

Is there a way of automatically picking up the render settings GC and adjusting them in the VSS prop in Python? Maybe that’s a feature which needs to be added as a switch (on by default?).
