• 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 v3 AN.AGN identifier

Is there a AN.AGN identifier number tool available to help identify a rogue file in my VFR PhotoScenery texture folder which contains thousands of an.agn files?

I've had a mysterious black square appear at Thrapston south of RAF Wittering and have sent days trying to locate it.
Its not a disused flatten bgl.
It does not show on the Autogen Annotator tool but all the vegetation does.

Pics show problem:-


I'm using P3Dv3.4 with VFR PhotoScenery covering whole of UK, I have'nt flown in this part of the UK for some time so don't really know where this has originated from. The scenery tile is V2-24-11765213 but would like to identify the an.agn tiles as well.


Hi Nigel,

You can use a tool like TCalc to find the agn file for a specific location.

But I'm not sure the agn is the problem, more looks like an issue in the photo scenery itself.
Hello Arno,

Thanks for swift reply, I did think that at first and re-installed Area 2 but it still showed up. I used idTileX to locate the correct .bgl and when I use the SDK Autogen Annotator the anomaly does'nt show on the Tool image at all, so thats why I think its an agn problem.
Where do I find the Tcalc tool?

Thank you DaveWG, downloaded and problem sorted.
That was my next task to rectify the problem: disable all my airfields one by one till image disappears, you've saved me a lot of work, cheers!
