Hello mutants from Mars!
Did I tell you that the rig process was the one I disliked the most?
Mixamo Auto-Rigger, please, return and do the job for me, please!
Well, after a boring couple of hours I'm glad to tell you, Nick is now fully rigged and his face expressions are ready to start in-game cutscenes!
These expressions are very exagerated, almost scary!
Because that level of expression gives me full control at the animation time (Not using them at 100%, but 70% more or less).
