• 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.

LOD's for high resolution photoreal

  • Thread starter Thread starter Spitz

Hello:

Just as one must 'enable' FS to display texture LODs via the Texture Resolution slider in the FS menu GUI, LOD's written into a custom photo-real aerial imagery BGL by FS SDK Resample must be enabled by the INF parameter 4,19 because "19" = max allowed (and required LOD) creation; this correlates with a 7.5cm texture resolution:

Hope this helps ! :)

Hi Philip,

a good reason to not use LOD=AUTO, for both terrain mesh and photoreal files, is actually the lower LOD cutoff. With AUTO it's always set to "0", which means the bgl will get started to be read into memory even if the user aircraft is many hundreds of miles away (LOD 0 = 90-degree grid block). LOD=4 brings that down to a much more reasonable ~6x6 degrees, which is plenty to have your file(s) loaded only when needed and thus prevents unnecessary file access/load operations.

Cheers, Holger
 
Thank you Gary and Holger, I was hoping you'd be the ones to respond. Much appreciated.
