trepang2 I need some help please

[OutLawJohn]

Hello there, I really need some help here please. I'm trying my best to figure something out for myself but for the life of me can't do it on my own and was wondering if someone could help me, I'm trying to do a weapon skin for the game Trepang2, just like the user DmgVol has done https://www.nexusmods.com/users/73248698 and here is a exsample of a weapon skin https://www.nexusmods.com/trepang2/mods/8

 

I have a edit a friend of mine did and I want to do a test on it but I don't know how to put it in the game.

Cheers.
