• 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.

building crash in FSX

I'm going through the process of adding old scenery to FSX and find that some scenery causes a dreaded 'building crash' even in slew mode. Others have also observed this. The odd thing is that I tried the same scenery on a virgin FSX + Acceleration install and it doesn't cause this problem. So the culprit has to be with a more complex addon (eg UTX, FTX or a module).

Anyhow, I did some debugging and found that FS2002 scenery seems to be the culprit. I'm still testing if the FS2002 header is causing this or some other FS2002 elements.

Anyone here been able to trace the problem in more depth? Would be great to get some older scenery working fine in FSX/SP2...
 
And I traced it down already. The good news is that it's not the FS2002 header. It's rather the way FS2002 gmax models define crash boxes. The following BGLC command causes this issue:

IFIN3 address_17504, xv, -757, 1289, yv, -34, 444, zv, -473, 1051

SETWRD crash, 14

So, just comment out the IFIN3 (not necessary, but might as well) and the SETWRD command. This will obviously disable crash detection on the building, but I'd rather have buildings I can drive through than having to turn crash detection off completely.

This is of course only going to help you if you either have the source files are know how to decompile FS2002 scenery.

Hope this is going to be of help to some people!
