How to work with gith skin texture in Volno's Texture Toolbox?

[MjrSpieler]

Hey guys,

So, loading textures is generally OK, and so far so good, I can see clearly I'm loading the correct maps for a correct character... But then, how do I handle color for a githyanki and their spots? What I'm getting after loading the textures is a gith body with basically correct textures but in a human-like color without spots.

I see there is a "Gith spots" item in the shader settings but I don't understand how to use it (and I think I'm missing the spot map, as I can't see them in the basic four map files [CLEA, HMVY, NM, MSK]).
So... How do I handle the toad-colored spotted gith with this great tool? :)

I'm using VTT version 2.1.1 AKA the latest one available and, with it, Blender 3.6.
