I have a problem with an Alembic animation.
I uploaded a test file with a single alembic animation: I can see it correctly in the web viewer, but when I download the usdz version and try it using my iPhone, the model is stuck in static pose.
I also noticed that every time I enter the 3D settings, the static pose is automatically set as the default pose, although I have flagged my animation and saved the settings.
I don’t understand if the problem is related to Alambic itself (that maybe is not supported in usdz and gltf files) or it is more related to an issue with the animation settings of sketchfab.
Does anyone had a similar problem or have suggestion?
Thank you in advance
