yes that us how its supposed to work you just drag and drop the files even if there the same, it wont replace anything and yes you can open them as winrar files
hey uhh i did exact steps. i put a glock skin and tested it worked. after that i added 4 more skins exactly how you said to put them there and all the guns where i selected skins i got the No Texture ´´skin´´. any idea of whats causing that?
Um. yes I can take a guess on whats happening, I am going to assume that the skins you added were not all for the same weapon so that clears the question of that, but if you added all those skins make sure that the folders you added are not excluding any important files or overlapping causing a improper detection. I'm sorry if this answer was not good enough so if this doesnt help add me on discord (pitviperpvp) and i can hop into a call or help you more there thanks.
when i download a skin theres no materials or anything like that. it just has 2 folders. sound and strike. a folder named strike with model and inside models is weapons and weapons is v_models and w_models.
