No valid blendshapes!

No valid blendshapes! There are no blendshapes to apply animation data to.

This message indicates that the assigned face mesh does not have any blendshapes that can receive animation data. This can happen if the blendshapes are not named properly or are not created at all. Please visit the Face System page for information on supported blendshapes and their naming convention.

If you assign a mesh to the Face Mesh with Blendshapes field in the addon, and that mesh has the "_FACE" suffix in its name, this error will appear if there are no valid blendshapes detected.

This means that the assigned mesh is not usable.

Please visit the Markerless Face Capture section of the documentation for more information on the face requirements.
