@splitshockvirus @dcc @eric basically: all models and other stuff will have to be synchronized manually by the players themselves, so you're basically relying on your friends installing the same exact mod pack as you, if you're gonna install anything to the server, then it will be only metamod, sourcemod and addons that have weapon txt and gamemodes.txt files in em, also like the case i brought up - models that are drastically smaller than the default model are recommended to install serverside for hitbox accuracy
also as far as i'm aware, not all vscript mods work on dedicated servers, my friend tried installing this one https://steamcommunity.com/sharedfiles/filedetails/?id=3061938834 and it didn't work, but it worked when i tested it in singleplayer on my end
