    Hi everyone,
    I’m currently working on an external launcher for BeamNG and I need to start a custom mission (built entirely in Flowgraph) directly from that launcher — without going through any in-game menus.

    So far, I haven’t found a reliable method.
    I’ve tried approaches like loading the mission JSON via LUA on startup, but none of them worked consistently. I’m looking for any supported or semi-supported way to:

    start a scenario/mission directly via command line,

    force BeamNG to load a specific mission when the game launches,

    or call an internal function (LUA or otherwise) that loads a Flowgraph mission automatically.


    Does anyone know if this is possible, or if there’s an internal mechanism I might have missed?

    Any help or direction would be greatly appreciated.

    Thanks!
