$0+
5 ratings

Sets the perfect pole angle for an IK constraint on any 3-bone inverse kinematic chain.

1: Select the pose bone that holds the IK constraint.

2: F3 search & select 'Perfect Pole Angle'. Boom!

To check for accuracy, make sure your bones are in their rest position, then toggle the IK constraint on and off. The chain shouldn't move a hair! :)

Compatible with Blender 4.0, and should work with some previous versions.

Notes:

-Works with any 3-bone inverse kinematic chain. Not tuned for any other chain length.

-The active pose bone that holds the IK constraint must be connected to a parent.

-The IK constraint needs a defined Pole Sub-Target

-Make sure "Developer Extras" is on under Edit >> Preferences >> Interface >> Display


F3 search for "Perfect Pole Angle"

View3D > Pose > F3 search 'perfect pole angle'


UPDATE LOG:

Version 1.1 (February 9, 2024)

There was a problem getting the accurate calculation when the base bone of the chain was parented to a bone. The new version calculates the pole angle separate of the parent. Problem solved

Version 1.0 (December 8, 2023)

Released to the public.
