Recreates a rig structure out of a CAT rig and constraint the bone nodes to the CAT nodes and adds a rootBone. It can also transefer the skin modfier(s) from old CAT bones to the recreated bones. This makes the rig exportable to game engines.
- Run CAT.RootNode by pressing the X button and search CAT.RootNode
- Also, you can assign a shortcut to it using Hotkey Editor
- 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
- Press the Add Nodes button to add CAT bones to the node list
- You can remove the bones by pressing the Clear Nodes
- 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
- Now Select the mesh and in the modify panel select the skin modifier and press the Add Skin
- 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
- 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
- Now each of your models has a new "Transferred Skin" and they are attached to the new nodes instead of CAT bones.
