Setting the Default Key

Each time you want to remove all facial expressions and go back to the neutral expression state, or when you want to remove the transformation keys (rotation, location, scale) and go back to the initial status, then follow the steps below:

1. Double-click on the desired Face key (in the timeline) to bring up the Face Key Editor panel. Please note that the key already contains offset data.
   

2. Select any feature in the Face Key Editor and drag in the interactive area to modify the model's features.
   

3. Click the Default Key button and the offset data will be cleared. The model will then turn back to its neutral appearance and the original key will be replaced by a neutral one.
