I've recently upgraded from 4.4 to 4.6 and my old SkeletonIK3D spine bender IK no longer works properly and I want to upgrade to the new system.
When it worked in 4.4 the settings were:
Lower Chest root_bone,
Upper Chest tip bone,
override_tip_basis disabled,
and a Node3D as the target_node
I tried adding a FABRIK3D with the same root and tip bones but all it does is flip my charactere's upper body upside down with no apparent way to control it?
If anyone knows a simple implementation I'd appreciate it.
