Audio2Face 2022.1.2 and above: "EXPORT AS USD SkelAnimation" option not available

Omniverse Apps Audio2Face

Hi!
I need to export facial animations to Unreal 4.27 MetaHuman. When I tried to use any Audio2Face above 2022.1.2, there’s no “EXPORT AS USD SkelAnimation” option available. I click on “SetUp Blendshape Solve” and this option to export doesn’t appear. Version 2022.1.1 is working fine and this exporting option is available. Without it, there’s no way I can export to Unreal.

Here’s the message: “2023-04-19 03:19:47 [Warning] [omni.usd] Warning (secondary thread): in ProcessPropertyChange at line 519 of C:\b\w\ca6c508eae419cf8\USD\pxr\usdImaging\usdSkelImaging\skeletonAdapter.cpp – Unhandled ProcessPropertyChange callback for cachePath </World/male_bs_46/joint1/bs_anim> in UsdSkelImagingSkelAdapter.”

(all my drivers are up to date)

Audio2Face 2022.2.1 was just released. Can you please try it and see if it works?

Hi! Thanks for answering me.
I’ve tested it in the newest version and it has the same issue. I tried to rerun Nucleus and tried other things like copying “male_bs_46.usd” from the version that works to this one, but nothing fixed this problem.

(I’m pretty scared because I depend a lot on usdSkel)

Oh I see what you mean now. That option is still available. It has just moved for organization purposes. Please take a look at this video: Audio2Face with Blender | Part 2: Loading AI-Generated Lip Sync Clips - YouTube

Sorry! I was not clear enough. I need “EXPORT AS USD SkelAnimation” option, but Audio2Face doesn’t generate this option after I click SetUp Blendshape Solve button.

I’m not using a custom head, and I don’t need to export weight as Json and USD format. I need a USD SkelAnimation to export this facial animation to Unreal’s MetaHuman. (USDA and other weight exporting are not working with Metahuman directly on unreal, only USD SkelAnimation is working with Metahuman on my side). Like this:

Here’s the error message: “2023-04-19 03:19:47 [Warning] [omni.usd] Warning (secondary thread): in ProcessPropertyChange at line 519 of C:\b\w\ca6c508eae419cf8\USD\pxr\usdImaging\usdSkelImaging\skeletonAdapter.cpp – Unhandled ProcessPropertyChange callback for cachePath </World/male_bs_46/joint1/bs_anim> in UsdSkelImagingSkelAdapter.”

EDITED:
**Solved! I exported it as USD ASCII to Unreal and had no errors anymore. **
Thank you!
