• 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.

    Hi Everyone! I created a custom Aerial Scenery, however, it comes with some default land "detail" texturing... for instance, on asphalt parking lot, there are huge cracks - it looks more like a Death Valley lake bed :rolleyes:. It makes the texture look messy and dirty. I would like to have a...

    Hello everyone, I'm using the latest SDK release as of November 11, 2022 v.0.20.3 for MSFS. I attempted to see the changes I made to my scenery with the SDK and after building the package, and viewing it in the sim, no changes were displayed. So, I can see my changes only during SDK mode but...

    [Help] Polygons in wrong place after building airport scenery

    For some reason in MSFS2020 when I place polygons and texture them, after I build the airport and load it, they are all slight moved and rotated. It's very infuriating. Any ideas what's going on here? You can see that the concrete square is not straight, and the polygon to cover up a white...

    MSFS Polygons are no longer working correctly! (MSFS 2020 SDK 0.7)

    Hello Folks I am still working on my custom made airport (EDHK) and today some users told me, that there must be some type of problems with my polygon exclusions. So I checked the scenery by myself and they are right. I use a lot of polygons for building exclusions, vegetation, texture & Co...

I made it in Blender, exported in collada (.dae), then in modelconverter x I exported it into .mdl, then with the ground polygon wizard I exported the mdl to bgl.

    P3D v3 [SOLVED] ADE does not compile GP with specular textures. (or bump)

    So the manual says include appropriately named textures as _bump, _detail and _spec in your textures folder of ADE and the P3D compiler will automatically include them in the material settings of your compiled GP BGL, but I have tested this on 2 different material templates and 2 different...

    Detail texture replaces texture it's supposed to enhance.

    Unless I completely misunderstand detail textures, they're suppose to add detail when zoomed up close but leave the texture looking mostly unchanged when viewed at a distance. No matter what I try, any detail texture I add to my ground polygon completeley replaces the original. This is the...

    Wrong Season Loads on Ground Poly

    I used MCX to add seasons to my Ground Poly. But whenever I reopen the BGL and set BGL_ZULU_DAY to anywhere between 335 and 31, instead of Fall textures, Winter is loaded. Same thing happens in sim. All other seasons work fine. Any ideas?
