    Hallo Arno,
    De ingevulde website heeft niets met FS te maken. Maar een andere heb ik niet.

    De autogenmerger is een zeer gewenste tool, daar valt weinig over te twijfelen.

    Wachten kan ik nauwelijks. Dus.. ik wil graag meedoen met de testversie. Ik begrijp je bezwaren, om hem nu al breed beschikbaar te maken. Die bezwaren tellen niet voor mij, omdat ik ( nog) niet eigen autogen gedefinieerd heb.
    Overigens maak ik al dankbaar gebruik van de vele tools die je hebt ontwikkeld.
    Op 3d Warehouse staan beschikbare werkjes van mij. Onder Arjo V.
    Hopelijk krijg ik een positieve reactie.

    Hi Arno, and thanks for another great piece of code that will make things a lot easier in the future for lazy people like me. Any chance to try your last build? I have the same issue as ydelta on the forum and was waiting for a new .zip to try! :’)

    Hallo Arno

    Ik wil me gaan verdiepen in het maken van autogen bestanden , met name van bomen.
    Maar ik kan nergens een begin vinden van hoe. Weet jij een manual voor beginners, groeten Joop

    Hi Arno,

    Hi Arno,

    I was wandering: is there an option for ACM to clear the added content after uninstall of the addon that used ACM method of writing into default.xml in the first place?

    That would be nice to have – to clean the things and e.g. have a clean install of the updated version of an addon

    cheers, Matt

      Hi Matt,

      At the moment there is no uninstall option. That would be tricky to do, as you never know if definitions are used by another addon and also many developers include definitions that are not their own (so uninstalling them as well would be risky).

    Hi Arno,
    with P3D V4 additional add-on discovery paths can be defined. Would it be possible to exent your tool in such a way that it also scans the sceneries defined in those paths?


    • arno says:

      What ways do you mean? The add-on.xml files are supported in the latest version. Is there another way?

  7. Ruediger Ebert says:

    P3D V4 enables the developer to add additional discovery paths. From the SDK:

    Add-on Discovery Path – Refers to the portion of the add-ons.cfg file which lists additional directories to search for add-ons in during the discovery phase of loading add-ons.

    In the add-ons.cfg additional discovery paths are referenced as in the following example:

    PATH=D:\P3D AddOn Sceneries\MyP3DV4Sceneries

    Hello, when I try to start the installer and “run it anyway” due to Windows message, no installer window appear. I’m trying to install in P3D v4.1 with Win10. Any suggestion?

    • arno says:

      Can you check the log file? The manual tells you where the log file is located.

    Good day

    Cannot fix the error – AutogenConfigMerger has stopped wor4king.

    P3d v4.4

    No visual model of the new Prosim 737 2019 PBR

    Not sure when error started.

    Thank you in advance.

    • arno says:

      You better ask support questions on the forum. I don’t understand the problem exactly, ACM does not influence aircraft models.
