Does Needle have any way of allowing multiple Animation Timeline tracks to affect the same object?

Are you using the timeline recorder with or without KHR_animation_pointer support?

42

I think Iā€™ve tried both, assuming you mean this checkbox - though a glance at the source code suggested it wouldnā€™t matter for our use case

Depends on where you use the files (KHR_animation_pointer isnā€™t supported everywhere), in Needle Engine both will work.

44

OK so on a first glance

  • animation export works
  • BUT always uses KHR_animation_pointer (which is a bug)
    Can you drop one of the exported files where you suspect animation doesnā€™t work into https://viewer.needle.tools and check if the animation plays there?
45

sure! but, for our use case, that wonā€™t matter - I only want the animation output, not the whole GLTF file, and the animation file seems to have zero keyframes in it

46

You can also drop it here if you want me to check if that is actually the case or if the extensions are wrong

47

ah, greater than 25mb, sadly

Any notes on how to reproduce the issue? At least it doesnā€™t trivially reproduce here when recording a complex animation with a GLTFRecorderTrack on the timeline

49

but thatā€™s how itā€™s lookinā€™ in Unity - maybe the animation name needs an extensionā€¦?

hooooly crap the animation is totally playing in the web viewer

by user 248501710404845568

51

That actually looks like the file does have the animation but with the wrong extension (which would be what I described above) - ok, thanks for confirming :slightly_smiling_face:

52

it was user error, yaay

53

Nah, issue on my endā€¦ Iā€™ll check why the bool for disabling the extension doesnā€™t work, and I was juuuust about to make a release, will see if I can get that fixed before

54

yeah realized that at the same time, even trying to give an extension myself doesnā€™t do the trickā€¦ is there perhaps an earlier Needle or UnityGLTF reversion I should try reverting to, or should I just wait for the release?

55

Actually what you can try right now (and what works here):

  • select the Assets/Resources/UnityGLTFSettings asset
  • disable the KHR_animation_pointer plugin there
  • record again

(conveniently we do only need transforms and blendshapes)

:+1: thatā€™s good :slightly_smiling_face:
Unity Editor import for KHR_animation_pointer is on the list but the team didnā€™t get to it yet

59

alright!! keyframes visible - thanks so much! hoping this does the trick, and will ping if thereā€™s any more problemsā€¦!

only other relevant item to this thread: the output is still pretty huge, and I donā€™t have the animation skills to do manual keyframe cleanup. Is there any automated tool for lowering the animation filesize by keyframe reduction?
