Of course I added the facial morphs and lipsync in poser. The software is much cheaper than the professional ones and it ain't perfect for I sometimes getting miss-tracked limbs and it cannot track hand, foot and head movements as of now. I am getting workable results. If you have a fast video card and speedy processor, it will benefit you greatly for tracking the movements will be faster.

Setting the scene is a little frustrating to beginning users but in my case, it is so easy for I understand the principles behind it.

Passion is anger and love combined. So if it looks angry, give it some love!
