After porting a MSFS2020 project to MSFS2024 lights work correctly.
However the project needed LOD adjustments for 2024 SDK build but the lighting was not changed but added to each LOD.
Exported using Blender 3.6.9 and Asobo exporter Version 1.3.3. Tried both Standard Lighting Mode and Raw(Deprecated). Built the project in 2024 SDK but the lights do not show in the 2024 Sim. The rest of the Blender build works correctly in the 2024 Sim.
Below are the lighting settings for Blender exporter.
There 3 new types of lights in the Blender exporter of the SDK code 2024 (which is the exporter you must use for MSFS2024). You should also update your Blender 3.6 to not use the deprecated lighting mode and use the multi-exporter instead to get your export correctly.
Sorry to take you back to this; look like the exporter can not actually export the light ? Try to just add a single light point using the 2024 method and export if it work; to me look like the gltf is empty with just a standard header without any light code; with or without any mesh.
