• 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 all.

The LOD has this type of range:

LOD Range

099-100 = 309-0
080-090 = 382-340
070-080 = 437-382
060-070 = 510-437
050-060 = 612-510
040-050 = 765-612
030-040 = 1021-765
020-030 = 1531-1021
010-020 = 3063-1531
001-010 = 30632-3063

I assume the numbers are meters.

In the above example, I had named components as *_LOD_099, *_LOD_90, *_LOD_80.... and MakeMDL figured the ranges:

    BGL_RETURN

... and so on...

It seems to be some sort of log scale (?)

Hi Dick,

Thanks for collecting this info, very useful. If I remember correct the VSize command takes a certain amount of pixels per meter, so I think in this case it is 1000 pixels for the given amount of meter (the values you listed). This means that the LOD also depends on your screen resolution.
