Stream Livelink Node Not Working After Reopening Saved USD Scene in Audio2Face 2023.2.0


Hi, I am encountering an issue in Audio2Face 2023.2.0. When I create a brand-new scene, everything works perfectly, and I can activate the Stream Livelink Node without any problems.

However, if I save the scene as a USD file and then reopen it (on the same PC with the same hardware configuration), I am unable to start the Stream Livelink Node. The following error appears:

css

[Error] [omni.audio2face.utility.scripts.utils] [StreamLivelink] the BLENDSHAPE NAMES input is empty. Please connect or enter a valid input before activating the streaming.

It seems like the Blendshape Names input is not retained or recognized after reopening the scene. Has anyone encountered this issue before? Is there a way to fix or work around it?

Thank you!
