Allows setting a Node3D as the reference target for BoneConstraint3Ds.

  • AimModifier3D
    • Works as a lightweight LookAtModifier allowing settings to be applied to multiple bones, but no advance options (limitation, timebased interpolation, origin setting)
    • It can be used for applications where you want to align the plane of the IK rotation
  • Copy/ConvertTransformModifier3D
    • Allows to transfer transforms in ModelSpace, which is useful for matching the tip bone of IK chain with IK target

The video below is a demo combined with IK #110120

constraint_with_ik.mp4

Other minor changes:

  • Vector to LocalVector
  • Add a defensive code on memdelete

Project file:
ik_test_match_target.zip
(require to merge both #110120 and this PR)
