Addons

For GMOD users, you will also need the Extended Spawnmenu addon to load any legacy addons.
Note: For all Pokemon addons aside from SV addons, the Shared Textures pack is required.
All vehicle packs requires the Shared Vehicle Assets pack. The Glide version additionally requires the Glide vehicle base as well as the previously mentioned prop version and shared assets pack.
Proxy Color Tool is required for the Mafia II Vehicle Pack.
To install GMOD addons, download and unzip the addon into the addons folder into "GarrysMod\garrysmod\addons" directory.
The addons will show under the "Addons - Legacy" folder if the Extended Spawnmenu addon has been subscribed.
To install SFM addons, download and unzip the addon into "steamapps\common\SourceFilmmaker\game\[CustomFolderOfChoice]" directory.
Note: If you haven't created a custom folder, then you will need to do the following first:
1. Create your custom folder with your name of choice.
2. Open your Steam Library and make sure to select 'Software' at the top of the list. NOTE: Source Filmmaker is NOT a game, it's software, so it doesn't show-up in the 'Games' list, only the 'Software' list.
3. Right-click Source Filmmaker and select 'Launch SDK'.
4. Select 'Edit Path for Selected Mod'. This will open a window with a list of check boxes, near the bottom of the list, you should find the folder that you made earlier with a blank check box next to it. Put a check in the box and you are done. Your folder is now enabled in SFM.
