  • 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.
  • “C:/Users/%USERNAME%/AppData/Local/ov/cache/Kit/101.0/d34aba4f”

Non English Windows Installation Issue

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:
