What do you mean with "intel one"? There's only 1 dds file in the mod folder as far as I can see.I've also tried to edit that dds. No change in the game though.
Yes, maybe it's the wrong encoder. There is also that intel one. Maybe that will work? Can you try it pls? I'm not at home right now. :)
*EDIT* When messing around with the Nature's Oath outfit, I noticed the lighting on the skin acting weird, like being blocky and all. So I redid it and cycled through the textures with ctrl+F3. That's when I saw that only the armor could be selected. And when I imported that into Blender and removed the vertices and exported it back and loaded it, the lighting on the skin remained unchanged.
Nature's Oath seems like the best candidate for a practically nude toon.
