Gain for Orientations with Rigid Body

[deborah]

Hi,
I'm using a rigid body plugin for tracking orientation and position data (Intersense is not an option). I want to apply a gain
on the orientation data, but link's postScale method only works for position data (nothing happens when I try link.postScale([x,y,z, target
= viz.LINK_ORI_OP). Is there a way to scale angular gain depending on orientation?

Thanks!
Deborah
