  I can't explain it because it's difficult.
  In Blender, retargeting (remapping) is necessary and difficult.
  I used Auto-Rig Pro.
  Even then, it's difficult.
  The bone names in the BVH files generated by R800ZZ Motion Capture are VRM.
  For VRM models, retargeting (remapping) is a bit easier because the bone names match.

• Leg IK: Auto -> Leg IK: Force Off

BVH is a text file.
sed can perform batch conversion of text files.
