Hi, to get round the problem of not being able to have more than one animation track in a timeline our artist is combining all animations for a track into one.

Unfortunately we are having a problem - the eye animation is not playing. Mouth animations play, but not blinks or other facial animations.

Here is a video of the preview in Unity of the blink animation (as it should appear)

#

Here is an animation of the build - no blinking, as you see!

#

I will upload a minimal scene showcasing the problem.

By not more animation per timeline you mean not more animation track per timeline affecting one target object, right?

As discussed here? https://discord.com/channels/717429793926283276/1129522556043534356

Do you get any error or warning in the browser console?

Yes, not more than one animation track per character per timeline.

#

Here's what I see in the console:

Ok thank you, it doesnt contain what i was looking for. I guess the facial animations are done with blendshapes? Do you see any special errors or warnings in Unity when exporting?

#

Yes, we use blendshapes for facial animations. Both for lip shapes and blinks and other expressions.

#

No particular errors on export

Hi just a quick update: a fix is in progress.
It was/is actually a multi-part problem that requires changes in three.js as well as UnityGLTF.
Then the result looks like this in the browser (The suit was just disabled for iteration speed^^)

If I may ask @carmine frigate , where's the model from? I wanted to put a facial animation demo / sample up for a while but haven't found one that was good enough quality wise

#

Thanks for your attention to this bug! The model is custom made for us using Character Creator 4.

Hi can you re-try with 3.11.4 @carmine frigate ? Thank you

carmine frigate Aug 4, 2023, 1:37 PM

#

Yes, she blinks now!

#

However I do get a lot of errors when exporting:

carmine frigate However I do get a lot of errors when exporting:

These are annoying and we'll look at them but shouldn't affect the result you get –
at most these should be warnings. Basically the IK targets can't be found since they don't really exist as objects that can be exported in Unity
