gmod playermodel content enforcer

sh_contentenforcer.lua

--Throw in addons/contentenforcer/lua/autorun
--Replace model name with path to ATLEAST ONE model
--Replace numerical id with the relative workshop id

--Upon player join they will be prompted to download missing content if any content is detected missing

--I'm just including my default models that I had
--Make sure to GMAD your player model content out and throw it on the server. FastDL sync but don't add it to resources.lua
--Content is downloaded the the garrymod/cache folder and automatically retrieved upon rejoin. If the cache file is missing
--or otherwise incorrect it'll redownload it. This means if your players rejoin they usually shouldnt have to redownload anything
--unless they wiped content.

--You can also add content without restarting the server, add the content to server, FastDL then update this script
--Script will automatically reload and all clients will detect the missing content
--Sometimes you'll get issues with the content not fully loading without a map change. Just try to map change if hotloading like that.

--Also recommended to have a steam workshop collection with all playermodels so people can 100% forsure without a problem download the content.
--This method isn't always 100% so always have the collection if people need it. This helps immensely though.
