I have a server up and running "nothing special".
I tried loading the maps from my pc to the server only to find out that I am missing Models and textures etc.

Is there a ftp or website or some resource available to get the popular maps and the associated files?

Any help is appreciated.

Missing models/textures on the server will always show up, you can ignore them.

Yes I am finding that whatever is not in the bsp file is an error on the map maker's part or they are using "non standard" models and textures.

I will just remove the maps that give me an error.
Some even crash the server into the "default valve config" .. "You are playing on the Valve Playtest Server" blah blah. niiiiiiiiiiiiice.

Also ... I search keywords "TF2 Map Downloads" and walla. Would ya know there are websites out there that actually host map downloads?
I was just more interested in the missing content, but good to know there are some reasources out there for content.

Thanks for your help.
