i’d bump this to blocker since aircraft rely on this in 2024 for animating the tyres

Could this be related?:

Animated materials not supported anymore?

Version: * 1.0.72.0* Frequency: Consistently Severity: High Context: Mounted from community, Aerosoft’s Lukla airport. Bug description: I created an animated creek along the airport through semitransparent layers of waves flowing down the creek using a moving UVMap exported through 3DS Max. In MSFS2024 they are not visible anymore. Not a big issue here as it’s only a little gimmick but I suppose this is a bigger problem for other addons that depend on it. Repro steps: Load Aerosoft’s Luk…

Thanks for checking, not really indeed

In this case the Blender exporter is not writing any animation related values in glTf files

(I made a test with previous version of the exporter and it did write something to the glTf…but that gave horrible errors when compiling)

Hello Mamu,

The issue happen because you are using two UV offset animations in the same time, while the game engine currently support only one.

To resolve this, clear the keyframes for the UV Offset V (set to 0 in your sample), leaving only the UV Offset U. This will allow the animation to work in-game.

I have also logged an issue regarding the lack of support for both UV offset animations.

Regards,
Boris
