If you mean you got the GCF Models and put it into your addons, that doesn't work your supposed to merge the materials folder (CSS) with your Gmod materials folder, same with the models and sound
Well it worked in gmod 10, but that might be crazy enough to work. I'll see what happens.
It works, thanks Juan.
Now the problem is that I fucked up my particles. I copied too much shit. If I shoot, I see black and purple squares coming out of my gun and every time I die, instead of the usual screen, it's just black and purple. Do I need to get the particles from the original?
