If you're seeing black and purple checkered things or ERROR signs In SSRP S1-2-3, then follow this guide
1-First subscribe to all those
contents and to this
map
2-And if you still have them then Download css content from here ( chose the one that you like but i recommend mega )

when you have done the download create a new folder in addons (you find addons in steam/steamapps/common/Garrysmod/garrysmod) and name it CSS CONTENT and then extract the thing you downloaded via winrar and put all those things inside CSS CONTENT (materials,models,scripts,sound,particles,addon.txt)
And when you have done those 2 steps run gmod and join ssrp and you will not see black and purple and errors any more
I Hope this guide help players
