Emissive and spot light not working when build in MSFS24

Version: 1.3.23.0
Hello,
I have an issue with emissive texture and spot lights

If i paste the MSFS20 project in MSFS24 community , everthing is working well.

But when i try to upgrade the project in MSFS24 / build , all emissive textures ans spot light doesn’t work …

Please help
Thank you

Before compilng/building the project, you will need to re-export the models using the Flight sim 2024 material (for the emissive texture to function) and also re-apply spot lights using the new 2024 SDK lights in MAX/Blender.

Hello,

Spots lights that are coming from the MSFS2020 blender exported will not work when creating (upgrading) your current projet into MSFS2024.

As @emilios said juste above, you will need first to convert your MSFS2020 blender/max project to MSFS2024 using the integrated feature and then export and finally build your project.

You can fin the related documentation here for 3DS Max, or in C:\MSFS 2024 SDK\Tools\Blender\addons\io_scene_gltf2_msfs_2024\documentation for the blender export
