TL;DR: I done did a thing:
I decided to make an AK in a cast.started by emptying out the wooden parts:
Then fill it with a plaster texture:
Casts are always covered in drawings. Let's make some!
Adding them on the skin. I tried doubling the texture so that I could render stuff on the other side but apparently CSGO doesn't allow that. the texture is actually not tiled in the files.
some views of the finished skin:
