I think it'll be a bit more complicated now since I made some edits to the textures outside of gimp so it's not as simple as editing the layer anymore
On the bright side I did some testing of my own on the weapons handling and most of them look reasonable in his hand now... except the laser pistol, which for some reason is way off the mark and looks like hell.
Thanks to Ajare who made the model, an unnamed texture artist who made the textures and Olfred for helping me import the file properly.
