This is the accompanying video for a guide I wrote on having characters within the Source engine have facial animation functioning properly.
It has 3 parts:
1st part demonstrates the character with speech only (No facial expression, or body gestures).
2nd part demonstrates the character with speech & expression (No body gestures).
3rd part demonstrates the character with all 3 animation components of speech, expression and gesture.
The guide can be read here:
