• 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.

    How does one go about editing a BGL file.

    Hello everyone. I have about 20 or so airports that I forgot I even own because they don't have the yellow star in the world map. After doing some digging I downloaded ADE to change the star value. ADE made a new package that I place in my community folder and it shows the star on the world map...

    ADE installations versions

    Hello, For a long time I've been using ADE v1.6x (I think it's either v1.60 or 1.61) it's been running great and all but if I want to install a second one the v1.78 completely separate from 1.6x, will both versions be working normally?

    MSFS Issue opening .bgl file

    I manually put in airline codes in the .xml file for an airport I'm working on (the rest was built in-sim). ADE opens the .xml file without any issues. However, when I export the package and try to open the .bgl file with ADE, this error occurs. Note that I could open up previous versions of the...

    Can't seem to find many airports in default scenery

    I've been using the BGL File Format documentation to read scenery files, so I can build a list of airports and parkings. I'll use this data for a small app to test CsSimConnect, by creating an AI aircraft at user-provided parking locations. So far all is progressing nicely, and I appear to be...

    P3D v4 Add dynamic lighting in sim?

    I have seen some tutorials on how to add dynamic lighting to P3D using model converter X. Adding the effect to a building and then overwriting an existing building BGL or adding the building to an airport with ADE.

    ADE not recognizing Flight Sim

    Hi all, I've recently downloaded ADE and I'm trying to choose my FS version. I have a grayed-out dropdown box, so I'm assuming it isn't recognizing where the flight simulator is installed. I'm currently running Lockheed Martin's Prepar3d. Do I need to install it in a different file path...

    Hello, I have spent a significant amount of time creating a photorealistic airport (LIMN). I premise that the terrain around the airport is not flat (same altitude). At south end of the airport I have an altitude of 541.5 feet at north end an altitude of 589.5 feet. Either altitudes have been...

    MSFS Adding custom materials - not supported yet?

    Scruffyduck, as far as I understood, there is no way yet in ADE to add custom runway/apron materials the way that the internal tools allow, am I correct? I read the manual's section on the materials/surfaces and it looked to me as if only what's already present can be changed around. Please...
