• 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.

FSX Lights not working properly after export on MCX

I recently started editing and adding materials to all the aircraft I fly to give it better reflections (my attempt to get some P3D-style reflections in FSX). I did this via ModelConverterX's material editor and adding environmental, fresnel and specular maps. I was quite impressed with the results on the Skyspirit 767-200&300 v5 (almost looked like FSX payware quality) but a reoccurring problem that I face is the lights. Before exporting, I was amazed with the ground illuminating lights, beacon lights and strobe lights illuminating perfectly but now, after exporting, the lights aren't working properly. Now, I cannot actually see the beacon or strobe lights even when their respective switches are turned on. Instead, I see ground illuminating lights that are continuously flashing despite its the respective lights not actually on. The taxi, logo, nav and landing lights are working normally. So far, other animations are also working just fine. I am aware that skyspirit lights are controlled via a control panel but I was able to control them directly from the VC before so that should nit be an issue.

What I tried so far:
- I tried exporting the model without making any tweaks via MCX to see whether adding the maps caused the problem however that was not the case. I still faced lighting issues.
- I tried adding the beacon lights provided by the model by activating it in the aircraft.cfg and removing the // but to no avail.
- I tried changing the visibility conditions so that the ground illuminations only occur when the light is on but no it does not work at all (no ground illuminations).

I have added an attachment to show how the lights are supposed to look (this was before I tried to export via MCX). Does anyone have any ideas as to why I have lighting issues after exporting :)?

P.S I am only exporting for personal use as to not infringe on Posky and Skyspirit's copyrights.
