Right way is to clone costume what you want. See step 2 here. You'll got folder with costume files, after unpack str2(cm prefix means costume male, cf means costume female) archives and there you get your cpeg textures. Then convert it to dds by this tool. Sufix _gl means glow. Edit texture - convert to cpeg - pack str2 archive - update asm - pack your mod with Workshop upload tool and save it in mods\ directoryHow can I do that? Unpack the costume textures?
