Installing
1. Extract the sh_accessory_system folder into your server's addons folder. 2. Open accessory_addons.lua. From there you can choose what Workshop add-on you'd like to enable; Enabling a Workshop add-on will make it, so clients download the content when joining. A list of supported add-ons by the script by default is provided in the file. Enabling a recommended add-on will automatically create the accessory objects to be added in the Shop. 3. In accessory_config.lua, you can configure the add-on to your likings. One important option to modify is SH_ACC.NPCSpawns which decides where the Accessory Vendors should spawn!
If you want to create your own accessories, run the sh_accessories_editor command to get started!
If you want to give accessories from the server's console, you can use the sh_accessories_give <steamid> <accessory id> command - good for donation systems!
