Hi 
When I start the JetEngine sample on iOS Safari and switch to Quicklook, the material animation does not work. Is there a reason for this, or is it simply not possible?

Hi Max,
The reason the airflow animation in the JetEngine sample may not play on iOS Quicklook could be related to the specific handling of animations in USDZ files. This environment has various restrictions and compatibility issues with animations, especially relating to how they are managed between multiple clips and playback exclusivity.
In the documentation, there’s a mention of a workaround for a known issue (FB13410767) where multiple animations on the same root may overlap or “glitch” instead of stopping one another. Quicklook is prone to these kinds of bugs when managing simultaneous animations, which could be affecting your airflow animation (see the documentation).
To integrate animations effectively in a way that Quicklook can handle, consider checking the following:
- Ensure that the animation components are not set to play simultaneously if their playback could conflict.
- Test if the animation works well when simplified to a single clip without other overlapping animations.
- Look into custom export options that focus solely on compatible animation settings for USDZ (see the documentation).
If you’re still experiencing issues, could you provide additional details about the specific configurations you’re using or any error messages you’re encountering? This will help in diagnosing the problem further.
Best regards.

The reason is, that Mesh animations, like the airflow, cannot be handled by Quicklook.
