Add-ons.

It's like Blockland but folders and not zips.

If there's a models folder, put the contents of it in the Garry's Mod models folder.

If there's a materials folder, put the contents of it in the Garry's Mod materials folder.

Etc.

I hate the Garrys Mod addons system.
I make separate Garrys Mod folders for every gamemode just so I dont mess anything up

No. 

Well, works for me. :V
