アークトラスちゃんでCats Blender PluginのFull Body Tracking Fixがエラーになるのを何とかするやつ

rename_bones.py

import bpy

bone_map = {
    "Root_J_New": "Hips",
    "Leg_L_J": "LeftLeg",
    "Leg_R_J": "RightLeg",
    "Hiza_L_J": "LeftKnee",
    "Hiza_R_J": "RightKnee",
    "Ashikubi_L_J": "LeftFoot",
    "Ashikubi_R_J": "RightFoot",
    "Koshi_1_J": "Spine",
    "Koshi_2_J": "Chest",
    "Neck_J": "Neck",
    "Head_J": "Head",
    "Sako_L_J": "LeftShoulder",
    "Sako_R_J": "RightShoulder",
    "Kata_L_J": "LeftArm",
    "Kata_R_J": "RightArm",
    "Hizi_L_J": "LeftElbow",
    "Hizi_R_J": "RightElbow",
    "Tekubi_L_J": "LeftHand",
    "Tekubi_R_J": "RightHand"
}
 
armature = bpy.context.scene.objects['Armature']

for old_name, new_name in bone_map.items():
    pb = armature.pose.bones.get(old_name)
    if pb is None:
        continue
    pb.name = new_name

BlenderのTextビューで読み込んでRun ScriptすればCats Pluginが期待しているものにボーン名が変更されます。
map部分書き換えたら他のモデルでも行けるんじゃないかな
