I'm getting this error when toggling the Contact Enabled field for the Interaction Hand script.
NullReferenceException: Object reference not set to an instance of an object
I took a quick look and I see that the contactBones field in the Interaction Controller needs to be set. I'm not sure how to do this though.
Is there an easy fix to this? This occurred on the Interaction Engine version 1.0.1 as well and resulted in some weird bugs with grasping. I haven't checked for the bug in the new version yet. By the way this error also occurs in the first Interaction Engine example.
