Hi! I make extensions for Blender & Inkscape, and MMD & Blender tutorials.

There are 3 types of bones that control legs:

  • Leg (FK): controlled by IK
  • Leg IK: (at the feet) controls FK leg chain
  • Leg D: extra FK adjustment when using IK (does not affect IK)

In MMD, there’s no convenient feature like FK-IK snapping, so even if you turn off IK or use Leg D, Leg IK bone won’t move. You should use Leg IK Parent for adjusting motions, or use Rigify Integration in MikuMikuRig / MMD Tools Append (so you can use FK-IK/IK-FK snapping).

Additionally, you can use MotionSupporter to convert leg FK motions into leg IK.
