After working with special effects makeup and animatronics for years, I was delighted to finally get bones and IK for 3DS. My first assignment for myself was to create a realistic articulated human head. Well, work is under way and it is looking pretty good, but I am trying to do some tricky things with IK to get my bones to behave like actuators I would create for a mechanical head. Maybe someone who has mastered the IK IPAS can help me out. I have a series of bones running through the upper and lower lips. What I want to do is set up the IK chain for each lip so I can grab the bone in the center of each series and move it around and have the bones on either side follow, with the chain anchored at the corners of the mouth, sort of like a rope tied at both ends to posts. Is IK capable of this? Also, I am having problems getting dampening to work right. I need the jaw bone to rotate without moving the rest of the head until it reaches its limits, but it affects the head when it is moved at all. I have tried to play with the dampening setting with no success. Does anyone have any advice? Thanks Mitch
