• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

P3D v4 A couple of questions...

About to test my add-on with the ACM tool.

1. Any thought to having the tool make a backup of the current state of the default.xml or the AutogenDescriptions files when installing? Thoughts?

2. What if a user already has my scenery installed with ACM and now I want to provide a "version 2" with new agn models or something but want to keep the same names/guids? What would happen?

1. The tool keeps up to 5 backups when merging new entries. They are in C:\Users\{account}\AppData\Roaming\SceneryDesign.org\AutogenConfigurationMerger

2. If you have two sceneries installed with the same entries then you can have issues indeed. Because it depends on the order of merging which results you get. If you update some models only that's a change in the BGL file only most likely, but if you change an entry it might be safer to give it a new GUID.
