A specialist is needed to work on an animal model in Cinema4D, who has completed the bone rigging and prepared it for proper export to Unity. The rigging is present but is not functioning correctly.
This work can be done in Blender, as I know it will be better suited for this.
A clean game-ready rig for Unity needs to be created.
The current rig from Cinema 4D has issues with:
- joint orientation
- local axes
- baked rotations
Because of this, the following do not work correctly in Unity:
- LookAt systems
- procedural animation
- IK
- runtime head/eye tracking
- animation blending
A completely clean skeleton setup is needed.
1. Rebuild the skeleton from scratch
Please DO NOT attempt to repair the current rig.
The current skeleton has:
- incorrect local axes
- baked rotations
- incorrect joint orientation
A new clean skeleton needs to be created.
2. Unity/Game-ready joint orientation
All joints should use:
Forward = Z+
Up = Y+
Right = X+
All joints must have the same logic for local axes.
3. Clean transforms
All joints in bind pose must have:
Rotation = 0,0,0
Scale = 1,1,1
Without:
- baked rotations
- hidden offsets
- pre-rotation values
4. Head/neck setup (VERY IMPORTANT)
The head bone must:
- rotate correctly in local space
- look forward (Z+)
- work normally with Unity LookAt
- not flip or rotate incorrectly
The hierarchy must be clean.
Example:
root
spine/body
neck
head
5. Eyes
The eyes must be separate objects/bones and support:
- eye tracking
- procedural eye movement
- blinking/morphs
6. Tail
The tail rig must support:
- procedural animation
- idle movement
- future runtime physics
Tail bones must be clean and evenly oriented.
7. Skinning / Weights
After creating the new skeleton:
- rebind
- reconfigure weights
- check for smooth deformations
8. Morphs / Blendshapes
Must preserve:
- facial morphs
- expression morphs
- blink morphs
They will be used for emotions in the application.
9. FBX Export Requirements
Export settings:
FBX
Y Up
Z Forward
Scale = 1
Do not export:
- helper objects
- controllers
- IK handles
- constraints
Only export:
- mesh
- joints
- morphs/blendshapes
10. Check before submission
Must check:
- the head rotates normally
- no flipping
- no strange rotations
- local axes are consistent
- the model works correctly in Unity
Final goal
The character must support:
- procedural behavior
- runtime animation
- LookAt
- eye tracking
- emotional reactions
- future IK systems
️ Important
A GAME RIG for Unity is specifically needed, not just a render/animation rig for Cinema 4D.
Compatibility with Unity is critically important.
