• 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.

Autogen Appears Despite Exclude Autogen Polys Used in ADEX

Good day all,

I'm hoping you can help me out with this, because I've run out of ideas. Long story short, I'm building a fictional country in FSX full of custom airports and cities using ADEX. For about two years now, everything has gone swimmingly- I've even been building road systems with vehicle links, and proper cities which can be driven on. Whenever I place a road, I always place a poly underneath it to flatten and exclude autogen, so that buildings and trees only appear in their zones, and not on the roads those zones overlap. However, about a week ago, autogen suddenly began appearing all over my roads, as if the Flatten Exclude Autogen polys were suddenly not being recognized by the sim. I've been trying to figure out how and why this has started happening, but have no idea. About a week and a half ago, I started messing around with SbuilderX and other terrain editing programs while attempting to build a mountain range in one of my sceneries, but couldn't figure it out and shelved the idea for a while. I'm wondering if messing around with a program like that may have triggered FSX to start ignoring my Exclude Autogen polys in my CVX files, but seeing as the sim still recognizes all of my flatten polys in those same CVXs, it seems to not support that theory, and I can't make any sense of it. I've attached a few pictures below, and any help is appreciated, as I'm still very much a beginner.

The first three images show a few different spots of autogen popping up overtop of my roads, though this issue is prevalent on just about every road on each of my 116 sceneries and counting. Up until a week ago, this was not an issue at all, and my Flatten Exclude Autogen polys kept the roads clear. The fourth image shows the polys laid down to keep the roads clear, in ADEX. Both the scenery files and associated CVX files have always been properly exported and sent to the Addon Scenery folder of FSX. FSX is also installed directly to the C:// location, and not in Program Files, to avoid potential permissions issues. Is it just me, or is this a real head-scratcher?

After thinking on it a little more, I went to my FSX main directory and looked for any recently modified files. Sure enough, one of those Terrain editing mods was to blame- it had edited my terrain.cfg file. Luckily, it saved the original for me, so after a quick restore, I fired up the sim and all is as it should be!
