Chain with FABRIK and Simulation Node

Hello,

I’m trying to do an ABP for chain of bone that is pointing to a target using a FABRIK node and when released it should switch to a falling simulmation (using an AnimDynamics node ideally, even a trail controller could do the trick). I don’t want to use Rigidbody physics or a physical asset though.

I’ve tried to work my way around my probleme with the alphas of the nodes by chaining FABRIK and AnimDynamics nodes (which behaviours individually are working fine). When I switch my alphas to turn off a node and trun on the other, my bones are snapping back to rest/initial pose and aren’t falling from their actual pose. Note that using blend in/out is not what I’m looking for, I want the animdynamic node to start simulating using the current chain pose as the rest pose.

Any clue on how to achieve such a result ?

Thank you in advance !
