if you don't have any preview skins, feel free to grab some of mine from this mod:

they aren't mine per se but I did take the vanilla textures and recolor them, re-worked them, mixed and matched them. you can grab a few basic, a few higher class, just to show off the various parts of the uv mapping

these are some good weapons, I just wanted to personally see some other skins on them in previews, maybe a sketchfab preview too or perhaps just renders, whatever you felt was alright. Someone told me to not post kenshi skins on a different platform and didn't seem to care whether or not the thing was downloadable or not
