I am not able to use Fac2Audio in with several models because I am getting below Error. I am attaching a pic of my Mesh fittings setup:

Hi @eng.qassim.ali
Thank you for trying out Audio2Face.
Are you able to share the face geometry for us to take a look?
Would likely need to look at your setup scene as well as it seems the error is on the correspondence index.
hi @eng.qassim.ali ,
I’ve recorded this video explaining what is happening and causing the failure and the current suggested workaround. We’ll look into how to prevent this and filter the mesh in the future.
The video appears too large for the forus, so I’ve uploaded it in google drive, here:
Let us know if it works for you, and we appreciate your patience :)
Thanks for your help. The model was exported from Houdini and imported as FBX then converted into Audio2Face.
I’ve add some subdivide, poly doctor and fuse nodes to remove some points and clean the model. But I faced the same problem. I exported the model later to Blender and re-export from Blender without doing anything and guess what! it worked! I do not know how and why. But maybe something you produce from your end and investigate.
So, I tired USD cache. But it does not export the blend shapes ? When I imported to Houdini, I noticed that the animation are backed on geo and no blend shapes were exported. I need the blend shapes to match to the original model.
