Last updated
Saves hold contraptions while addons change the toybox. Legacy addons live as folders inside addons under garrysmod. Workshop subscriptions mount automatically beside them.
The existing saves post covers save files; this one covers the addon side. Mount order follows load priority with conflicts resolved alphabetically. Dupe files reference addon content by path.

Frequently asked questions
How do I install GMod addons?
Subscribe on Steam Workshop and let the game mount items at launch, or drop legacy addons into the addons folder with folders matching lua or materials trees. Workshop covers most needs while the folder serves friends only packs.
How do I back up a modded install?
Copy the addons folder plus saves and data from the saves post with the game quit. Legacy addons travel as folders while subscriptions mirror in Workshop. Removing a vehicle pack deletes its spawns from saves.
