• 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.

FSX Ground polygon layers order

hi everyone
I am making a GP but I have a terrain issue.
I made a GP and converted it with MCX using ground polygon wizard and set the altitude to 250 meters
then I used ADE to modify and edit some taxiways of my airport and set the airport altitude to 249.50 meters, then made a flat terrain polygon also using ADE and set it to thesame altitude of the airport but I have parts of the terrain showing trough the GP even when the GP altitude is higher than the flat poly and airport altitude so my question is: what goes first or which is the correct order to place the layers
The altitude set in the GP Wizard, the airport altitude, and the flat terrain polygon should all be the exact same value. You are seeing the terrain showing through because the GP Wizard is different. FSX will place the ground polygon on top of landclass textures, aprons, and runways. The ground polygon is drawn last by FSX. Layers in the ground polygon allow you to create tire marks or cracks for instance on top of a concrete texture that makes up your runway.
