In the Node Editor, press the Tab key and create a boneDynamicsNode.
Connect two joints in a parent-child relationship, one boneDynamicsNode, and one time1 node as follows. This is the minimum setup required for the node to function:

  • time1's Output Time → Time
  • Parent joint's Translate → Bone Translate
  • Parent joint's Joint Orient → Bone Joint Orient
  • Parent joint's Parent Matrix[0] → Bone Parent Matrix
  • Parent joint's Parent Inverse Matrix[0] → Bone Parent Inverse Matrix
  • Child joint's Translate → End Translate
  • Output Rotate → Parent joint's Rotate

Note

  • The time1 node already exists in the scene. Do not create a new one.
  • For attributes with constant values (such as Bone Joint Orient, End Translate, etc.), you can disconnect them after making the initial connection.

minimum_required

Move the time slider to frame 1 or later, then test by moving the root joint.

Note
Disable "Cached Playback" and set "Playback speed" to Play every frame.
