CAT.RootNode

Transfer the CAT rig and skins to a new rig structure with a root bone

Video Tutorial:

How To Use:

1. Run CAT.RootNode:

• Run CAT.RootNode by pressing the X button and search CAT.RootNode
• Also, you can assign a shortcut to it using Hotkey Editor

2. Selecting the CAT bones:

• Select All the CAT bones, try not to add the wrong type of nodes like IK, Handles, ...etc
• Also script filters the nodes and just let the "CAT one / Hub Object" class go through

---

3. Adding the CAT nodes:

• Press the Add Nodes button to add CAT bones to the node list
• You can remove the bones by pressing the Clear Nodes

4. Recreating the rig structure:

• By pressing the Recreation button, create new bones with a root bone
• New nodes have the same Name, Color and Position
• Also the position and rotation of the new nodes are constrained to the CAT bones

5. Select the Model with Skin Modifier:

• Now Select the mesh and in the modify panel select the skin modifier and press the Add Skin

6. Adding more Models:

• If your character has more than one object with skins repeat the process and add all of them to the list
• If you have selected the wrong model you are able to select it in the list and remove selected from the Skin List
• By selecting the object in the Skin List 3Ds Max will select them

7. Transfer the skin data:

• Press the Skin Transfer button to transfer the skin data from the old modifier to a new one named "Transferred Skin"
• Note that your old Skin modifier is still there but it's disabled

8. Enjoy!

• Now each of your models has a new "Transferred Skin" and they are attached to the new nodes instead of CAT bones.
