Help Tether for ropes and rods?

Just make sure you're using dynamic attachments. Static attachments (the default) are one-way only, which means the rope will blindly follow the rigid-body it is attached to without applying forces back to it. See:

Thanks I had looked at each of those but re-reading them was helpful. I found that the Obi Rigidbody was coming in with "Kinematic For Particles".  When I turned that off it started working.
