• 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.

Landsat7 terrain in FSX

Hi. I'm new here

I'm working in develop landsat7 for fsx. I used to do this for FS2004 (FS9) with very satisfactory results and it was a very hard work to do. Now I begin to work in the FSX Terrain SDK to make the same satellite sceneries with excellent results, like a thent of the FS9 disk space for the same scenery, a very fast load of the scenery starting the simulator and only one bgl file instead 6,700 texture files in the previous version.

But I have a trouble with the default sceneries, because when I start near the center of my new scenery (a whole square degree) appears the default scenery based in landclass and the autogen objects in a radius of about 5 to 10 miles, but in the far is my scenery and when I move, my scenery is substituted with the default.

FSX SDK doesn't make any remarks about this issue. Anybody has experienced with this, like me?

Thanks in advance.

Hi Juan.

Your INF file may need to be adjusted.

Under [Destination], you should have a line for LOD.

LOD = 2,15 might give good results. The lower LOD number will determine the lowest level LOD ( and distance ) at which your scenery will show.

Thanks rhumbaflappy for your opportune reply, but in my case those settings generate a very large file (I aborted the process when I see a 150,000 cell file) so I work in a LOD 12 (1600 cells) and LOD 13 (6300 Cells), but in none of those cases have a satisfactory result. My scenery created with the SDK for FS2004 with 6300 files (cells) works fine in FSX and I didn't have that issue, so it is frustrating that with the new tool this thing doesn't work as I expected

Hi Juan,

Do you have this problem only at a certain spot in your scenery or does it always happen in the area closest to your aircraft?

I am wondering if the problem might be that the landclass images have such a low resolution that the scenery engine replaces them by a higher LOD of the landclass automatically for terrain tiles nearby the aircraft. Just guess though, I haven't tested this :).

Thanks Arno

The spot of default landclass scenery with autogen is dynamic and depends on the localization of my plane (always in the center). but when I regenerate the scenery with a LOD value of 12 the results were exactly inverse: Satellite arround my plane and default at far distance (about 5 to 10miles, but with autogen over the satellite terrain. Then when I used the Lod=13 parameter I have no satellite scenery at all. All scenery, near and far, was default.

I’m doing more tests in different configurations on the .inf file, but the idea is that maybe there is some parameter in the FSX.CFG or Terrain.CFG files to avoid this issue.

Again, thanks for your help.
 
Hi Juan.

Try LOD = 2,13. That should give you what you need.

You also might need to use this in the Destination:

CompressionQuality = 85

This is 85% compression... hardly noticable in the sim, but it drastically reduces the file size.

Thank You!

I resolved the issue with your useful advices, setting the Lod parameters (with a maximum of 12, disabling autogen and setting the texture size to 10 meters. It works great.
