Perfect Pole Angle for IK (free Blender addon)
🕑 Added 2024-02-09 15:52:55 +0000 UTCSets 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.
