5.6.0: Breast Flatten Shape Key Added

• A new button to generate a flattened breast shape from your well-endowed model, by automatically creating shape keys that can be used as blend shapes in third party software.
  • This is far from perfect, but it's a good starting point. You will need to use the Sculpt tool to improve the topology.
  • The max breast size is what the model starts with, so you can't make flat chested models well-endowed. Give them surgery in VRoid Studio, then try again.
  • When the button is run, it automatically will set the shape key to 1, fully flat.
  • Change into the Sculpt Tool. Use flatten, inflate and other tools to first better shape the breasts since the flattening might be extreme and unrealistic. Then, adjust the middle section and the neckline of the model by flattening it to the same height with the scrape tool.
  • The extreme value of 1 is pretty much unusable depending on the model, so it's best to use it up to 0.8 in practical applications.
  • Shift the key back to 0 and then export your model. In relevant applications it should show in the blend shapes.

5.5.1: Scale bug fix

• Fixed a typo that caused errors when scaling models.

5.5.0: Gravity added

added gravity

5.0.0: Optional 4th Chest Physics Bone

• A preset system has been added for the breast physics: discreet and bouncy. Select and confirm to apply the values to the UI. You'll still need to run the tweaker before changes are made.
• Added the option to use 4 bones for the breast physics. It does enhance the effect for bounciness.

4.0.0: Scale model with better physics

• A new option to scale the model has been added: unlike scaling the model normally through other software's scale factor, this one both scales and adjusts the physics of the model so that it resembles the original model's physics at x1 scale. This should prevent excessively low gravity hair and other physics related horrors at larger scales.

3.0.0: Bust Ends Weight Region Tweaks

• A new option to configure the weight distribution of the bust bones, and attribute weight to the 2_end bones, which by default do not have anything assigned. This should help create more... dynamic motions.
• UI Updates.

Long Dress and Body Jiggle Physics

• Added Long Dress physics adjustment and a simple subdivide skirt option.

  • Use the settings to configure the physics before applying the changes.
  • Subdivide skirt through the topology settings can be used before or after the application of long dress physics.
  • By default, the settings work OK-ish for a simple VTuber who is stationary, but breaks hard when used in a game engine with lots of forward velocity.

• BETA: Added the Jiggle Physics implementer for various parts of the body, like thighs and spine, to simulate some kind of zoneless zen zero-like physics.

  • Use the settings to configure the physics before applying the changes.
  • By default, it works fine enough for a simple mostly stationary VTuber, but breaks hard when used in a game engine with lots of forward velocity (skinny bone effect, chicken leg effect, etc).
  • The effects can look very artificial at times, or really convincing in certain scenarios.

• UI Adjustments

Initial Release

A simple utility to add some colliders for the bust, arms and some "attempt" at preventing long hair from piercing the body.
