• 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.

FSXA Multiple tweaked ground polys?

A question that can probably only answered by Arno, but I'll post it here since it might be interesting to other developers as well:

Is it possible to use multiple tweaked ground polygon files without them interfering with each other?

I use this method for some time now to hide shadow and light layers at day/night. This gives me 3 different bgl files (normal ground poly, shadow layer, night layer) which works just fine.
Now I played around with another new layer, almost identical with the shadow layer. Just this time the new layer conflicts with the ground poly. As soon as I move the tweaked bgl file with the new shadow layer in my scenery the complete ground poly disappears.

Could this have to do with Area definition, LayerCalls or RefPoints in the sca files? It seems those are the only reasons why it would not work properly.

Hi Thorsten:

Do you mean the G-Polys are superimposed above each other as layers with (different VTP layer numbers) ?


And when you state: "As soon as I move the tweaked bgl file with the new shadow layer in my scenery the complete ground poly disappears.", do you mean you moved G-Polys horizontally on the X or Y axis ?


Or did you instead mean you changed the "new shadow layer" to a different VTP layer number ?

And if you meant that you changed the "new shadow layer" to a different VTP layer number, was it a higher or lower number; and did it by any chance match a layer already in use by a (known and documented) layer from default or 3rd party scenery content ?

Thanks for sharing more info with us regarding this interesting development method. :)

I meant I moved the file into my scenery folder because after I got that issue I removed it and found that the gpoly works fine without it - but if I put the file back the other gpoly disappears.
The issue is still not solved although I found a way around it. It had nothing to do with 3rd party sceneries though since I always make sure those don't interfere.
I think it has to do with the area definition. I remember I had a similar problem when I wanted to use SCASM (3D) objects in combination with gpolys. I had to change the area definition layers on my 3D model in order to make both work together. But I really have no idea what I could change in the gpoly SCA file to make this work.
