So I have read a lot of comments asking "How do I put these into Gmod?!"
Well I am here to help with that! I use windows so this is going to be from a windows perspective.
First you need to have WinRAR or 7Zip (I use WinRAR) then you want to find the .zip, .rar file for the model and you want to right click it.
Then you want to click on the "Extract Files..." option.
After that you want to go to your steam/steamapps/common/GarrysMod/garrysmod/addons
Then click OK and wait.
If you don't have it already then get the extended spawnmenu addon. http://steamcommunity.com/sharedfiles/f ... =104603291
Then start up gmod, load a map, go to Legacy Addons and spawn your models :D
I hope this helped, sorry for no pictures, windows doesn't have that option.
