Native Qbox support
Every script has its own Qbox bridge that talks to qbx_core directly instead of going through the QBCore compatibility layer.
ox from top to bottom
Items go through ox_inventory with their metadata, interaction runs through ox_target and the interfaces sit on top of ox_lib. Nothing extra to install.
Installing on Qbox
Put the folder into resources and ensure it after qbx_core, ox_lib, ox_inventory and oxmysql in your server.cfg. Database tables are created on the first start.
Questions
Is Qbox treated like QBCore?
No. Qbox is detected as its own framework with its own bridge.
Is there a separate Qbox download?
No. There is one download for every framework. The script detects Qbox on its own.
