Downloading again and again...

On my new DarkRP server (68.197.188.181) My computer as well as everyone elses redownloads half the crap on my server EACH time they join. Is there any way to stop this? I tried using the AddDir(“BLAH”) thing, but that didn’t help at all. Even still i am downloading missing textures for PC Mod, EVERY fucking time I join my server and the materials and textures that I download are STILL fucking errors. Seriously, wtf do I do?

You could download PCMod onto your computer, instead of relying on the server.

But that wouldn’t fix it for other people is what im getting at
