Recently, I made server on my PC to play with friends.
So I searched for cool maps to play on.
I found a map, cp_orange_final but when I launch it, surprise! There were some textures missing and it wasn't playable, because the principal tower is invisible!
So I let this map, thinking it was an exception.
But I have found another map which has textures bugging.
I have searched why but the answers that I found not satisfied me.
I think I must download some files, but I didn't find what and where.
If you have the server running off your PC you shouldn't have any problems with missing content as it'd be present on your disk. Usually this issue occurs because someones TF directory on their PC doesn't match the content on a dedicated server. Is the issue just for other players or also yourself? You could try varifying your files through steam.
Most releases of maps have the content embedded into the bsp file by the author so you don't have to worry about missing content as it's unnecassery to install a ton of custom content in your TF directory when they do this. My first piece of advice would be to avoid maps that have these issues; because they are poorly made.
I'm afraid with your ambiguous explination this ambiguous advice is all i can manage.

Sorry, but I'm French and it's difficult to explain this in English.
First, the map should looks like this:
but it looks like this:
The issue is for me and 4 others who had joined the server with this map. One of them had already played on this map, and there were the good textures.
And when I try it with the built-in TF2 server, it works!
So I think there are some textures which are missing, but are on my computer. How can I retrieve them?
So when you run the map on a listen server (through Create Server) the maps are fine, but when you run the map from your server (is it a dedicated server? I'll assume it is) some of the content is broken?
Check there isn't any missing content and such in the server files.
