I believe data from that archive is being used when an entity/weapon/map uses it. The problem with garry's archive is he didn't include any Lua or metadata, so we need people's caches of the Toybox Lua/metadata and the garry archive content then gets used if the Lua calls for it. Pancakes would need to clarify if I've got that wrong. Thanks for offering though!

The main thing we're looking for is cached content from anyone who has a backup of their Gmod 12 install or still has Toybox content cached in their current Gmod install (the 13 update didn't clear it but most people have re-installed since then), as that content is still in Toybox format and can be verified and added to Cloudbox. These are usually the folders: "garrysmod/config" "garrysmod/toybox" "garrysmod/addons/toybox".
All entities/weapons/maps/metadata on Cloudbox are from caches people have shared with Pancakes.

Ahhh, okay. I know a major portion of the content from garry's archive is maps, materials and models, but you're right- there's no lua or metadata. I believe all the maps, props and materials from the toybox are in that archive, but none of the actual lua. I wish the hard drive I had Garry's Mod 12 on didn't die, else I would've provided metadata! I'll surely look around and see if anyone I know has their install still :D
