I've been experimenting with different Export settings trying to get the bulk of the 100+ Digital Soul facial expressions into Unity 3D.
Through my couple hours of testing I found that only when using the "Current Animation" selection of the Export FBX settings was I able to import the facial expressions in their full glory.
Using the "Custom" export of bulk .italk animations (at the time of this writing) does not export the facial expressions properly.
Just wanted to report my findings if anyone else was trying to do the same.
To recreate this bug;
Export multiple .italk animations using the "Custom" selection of Export FBX.
Current fix;
Export facial .italk animations one at a time through the Export FBX using "Current Animation."
