WHAT IS BOOB JIGGLE?
…Seriously, do you even need to ask?It’s what make those BOOBY bounce in
3DGames!
SO, HOW DO WE DO IT?There’s some options available.1. PreUnity-Baked animation
Manual Animation in DCC tool and Baked Physical or Spring-base Rig in DCC tool and
Baked2. Unity-In game Physic Calculation
Code base Physical Calculation Joint Base Physic Component
KEYFRAME BASED
The Bad:Same in-Game result, not affected by other in-Game
Factors.
The Good:Light on Game engine as extra Runtime process isn’t
needed.
What ever your DCC tools of choice is,Make it in there, then import to Unity.
IN-GAME PHYSIC CALCULATION
The Bad:Require Intensive Setup
The Good:Affected by In-Game factors. Adjustable.
Set it up in Unity and make it bounce while character move
MECANIMIn order to use Mecanim’s ability to transfer
animation across rig. A test was conducted
Models with various settings were used
From the Right:1. Original FBX with Animation2. FBX with no Animation
Attached, moved via Mecanim Controller
3. 2 with Added Physics
4. Test model with same Bone Naming structure
5. 4 with Added Physics6. Test model with different Bone
Naming structure7. 6 with Added Physics

RESULTFrom the test, these conclusion were found1. In order for extended bones on the boobs to move as
in original Motion,The bones must be named with the exact same Naming Structure.
2. Added Physics can be lay on top of keyframed Boob bones.
3. In order for the boob to be solely dependent on Physics,they must not be keyframed upon export.
