  • Basically, sometimes the copy of the ‘shadercache’ files does not complete on the first run and you end up with a broken shadercache directory, and subsequent runs will error out due to this broken shader cache.

Solution:

  • You will have to delete shadercache with path below and start the app again.

Non English Windows Installation Issue - FIXED

(NOTE: This issue has been fixed from Audio2Face2021.2.4 and on)

Windows OS version being older than 1909 + Non English based Windows OS

Audio2Face_failed

  • Right now pre_install.bat approach to checking Windows OS only works for English version
  • Non English Windows are failing to install due to this

Solution:

  • A new patch is being worked on to fix this, will announce once this is released.

Forum User solution from tymaho

However, I was able to fix it by replacing the files:

C:\Users%USERNAME%\AppData\Local\ov\pkg\audio2face-2021.2.3\exts\omni.audio2face.core_deps\deps\py_sounddevice_data\portaudio-binaries\libportaudio64bit.dll

and

C:\Users%USERNAME%\AppData\Local\ov\pkg\audio2face-2021.2.3\exts\omni.audio2face.player_deps\deps\py_sounddevice_data\portaudio-binaries\libportaudio64bit.dll

With the file portaudio-r1891-build.zip\portaudio-r1891-build\lib\x64\Release\portaudio_x64.dll (Rename this file to “libportaudio64bit.dll”) in this zip file:

GENERAL FAQ

Mesh Fitting Panel missing after Mesh Selection

Solution:

the Mesh Fitting panel is not expanding because it silently failed to find the Default Prim in your Usd Stage. (We will avoid this error in the future release).

Meanwhile, you can set the Default Prim on the top node of your mesh by Right clicking on it on the Stage view and choose Set as Default Prim .
image
Once you set this, try reselect the mesh again in the Meshes panel.
And Mesh Fitting panel should show up again
