Hey DevTeam,

just noticed that when I chose to bind an object to eg. head center, facial movement like the eyeblinking or eyebrow lifting is moving the anchorpoint for the binding object - thus moving the binded object...

cheers el.

  Hi el, can you give a step by step on what you are doing? I am unable to reproduce this by:

  • Create a head binding
  • Make sure head binding is set to head center
  • Create a cube. Drag so that it's a child of the head binding
  • Move your eyebrows / blink

  In the above example, I see very subtle movements when you move your eyebrows. But pretty minimal and doesn't break the experience.

  Hey Travis - most probably that is the movement I notice as well.My setup is just like you outlined.

  I did it with a particlesystem where the particles should STICK to the Hair around the head, so when the head moves slightly, the particles in the hair should move likewise. In this case it´s very noticable when the particles suddenly shake without a head movement - caused by the eye-blinking of course. it might be picky, but in my case it sure doesn´t fit in. 

  technically analysed: is it possible that the headtracking relies on facial targets like eyes,mouth,nose and averages the position where it lets me bind my objects? in this case - and that´s how I find my explanation - the averaged pinpoint shifts as well when the eyes lift up or the mouth expands....

  maybe there is a way to define a target that is more persistent... don´t know.
