How does one get a CSS skin into a Swep for Gmod?
I’ve never worked with SWEPs and I don’t know much about Lua, but I’d imagine you’d need to code the SWEP so that it uses that skin, and you might also need to hex it. you’ll probably get a more informed answer if you ask about it in the Lua section.

but you can always just install it like you would if you were installing it for CS:S, if you’re okay with using the CS:S weapon’s values and you don’t want it to do anything nifty.
