oh so how would i do that
Assuming the texture you have is for the world model of the knife, it won't work properly for the view model version of the knife, so there isn't much you can do about it except look for other skins that are either A) Made by competent people who know how to organize and name their files and folders or B) Made after the Steampipe update
Where did you get this texture from anyway, do you have a link to it? Perhaps i can see which knife it's for at least
They already told you. Rename it to "w_knife_t.vtf"
That's no longer the issue here, the issue is that i'm not sure if it's for the world model or the view model knife and i think hillkill wants it to re-texture the knife in first person
