Interesting, thanks for the bug report. Which version of Filament are you using? We merged a workaround for a Mali-related issue on May 13 (#5557).

In v1.21.2 we were still using timer queries, which we discovered are problematic on older Mali drivers (look for `dont_use_timer_query` in the code) It's interesting that your issue is triggered...

I think it would not be difficult to write a small animation helper in Kotlin, and put it in `filament-utils-android`.

A single glTF asset contains an array of `animation` objects that can be referenced using a zero-based index. Each animation has a duration (which is implied by its max length...

Filament cannot have dependencies on any Sceneform types, it sounds like your project might suitable for its own repo. According to the glTF specification, the weights that get animated are...

If we add a weightFactor to the applyAnimation function like @ThomasGorisse proposed, then I think that demo UI in that animation should be possible, right? To blend animations, clients can...

@pixelflinger this is a common user request but I recommend closing this issue and directing users to [the sceneview-andoird library](https://github.com/SceneView/sceneview-android) and @ThomasGorisse.

I believe this is a dup of #4922, which we closed as not actionable since it is likely an NVIDIA issue.
