SmartBone 2 - Simulated Physics and Collision solution for Bones

This is great, I love SmartBone V1 but for some reason, V2 doesn’t work with a set of a bunny ears that i made which worked with V1. Im not sure what the issue is, they just dont move, at all, in my place, in the testing game they sag and do not replicate the desired effect.
This is very frustrating and would like to ask for help.
