• 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.

FSXA BGL_LIGHT and LOD integration

All,

I'm working on some of my runway lights and I'm having a bit of trouble.

I was able to get my runway light fixtures working with separation planes using the FS2002 MakeMDL. Unfortunately, I was trying to place all of my lights within my Max 8 model, and I found that although the 3d geometry would correct itself for the "round earth" issue, the BGL_Lights would not. Instead they would either float or be below ground depending on where they were in the scene.

I decided to make each light a library object, and place them by hand using Whisplacer. This worked fine, except I compiled all of my models without LODs, so it was an immense drain on performance with over 350 fixtures for just one runway.

I searched high and low for the proper way to do LODs, and I found many half-explanations. I tried methods meant for the FS2002 SDK, and the FS2004 SDK. I didn't bother with the FSX SDK, because I need to add a lot of separation plane checks, and I understand the FSX native exporters won't allow you to tweak the .asm.

I eventualy figured out what I think is a "per-part" LOD scheme that works using the FS2004 MakeMDL/BGLC_9 combo...I think.

But although I can place my fixture with Whisplacer, the BGL_Lights are no longer appearing at all. What gives?

Can anyone tell me if there is method that allows for LODs (Just two of them), and BGL_Lights at the same time? Preferably using the FS2002 MakeMDL/BGLC_9 path?

I just want my fixture to disappear while leaving my lights intact.

I've included my .asm files as well as the original model for my fixture in case it can help diagnose my issue.

Thanks!

Nick
