I try to refrain from doing people’s work for them. Considering this is a help forum, all that does is moves around the problem and then they end up stuck again later on.
I had to fix some stuff and get the model recompiled, and I’ll fix up the textures a bit. They make my eyes sting.
The hair still does need to be either welded or smoothed (whichever it is). I’d do this for you, but importing SMD files with my version of max truncates the smoothing groups which doesn’t help.
I cleaned up the VMT files and slapped the values I used for Vella in them, though this was for the skin. Vella’s skin is separate while this just uses a single material. It also looks like half the materials/textures are completely unused.
I’ll probably split the leather and such later to make it look nicer. I also just discovered what lightwarp does to that cloth. It looks really great in my opinion. The light refracts in a manner that makes it look a lot like a real cloth.
Anyway, there’s a lot I’d still do, but I can’t do much without being able to really touch the model. If you want to bother with these material edits, upload the .max or .blend file if possible along with the edits cra0kalo did so we can also avoid having 3 different versions you’re trying to figure out how to use. I’ll try to write up an explanation as to what I actually did so it’s still worth something in the end. Aside from that, if you don’t wish to bother with it or you’re happy with what you have now, don’t worry about it.
On a side note, you don’t need a material for every texture you have. It looks like all that is spat out from something like wallworm, but if it isn’t, you don’t need to use a material for each mask and such as well. The material just tells the engine what textures to use, what shaders to use, what values to use, and so on. It’s not really needed to tell the engine the texture exists before being used by another material.
