Constraining Height
For an upcoming study, I'd like to constrain the height of the subject while still rendering the relative y-position of the subject from thier starting point.
I understand that it would be trivial to simply not render the y-position and set the eyeheight to be constant, but is there a way to:
1) set eye-height at reset
2) subsequent y-position movement is rendered relative to this starting point
In other words, I can set a subject to be 1 meter or 2 meters tall, but if they crouch down or tip-toe, they can still get taller or shorter relative to their starting heights.
What's the easiest way of doing this?
