Naturalis v1.3
  • Soft physics mesh pressure - expand mesh to maintain volume using an internal pressure force
  • Soft joint depth physics - dynamic changes to soft physics based on surface depth
  • Softness separated into Softness (Soft Physics) and Softness (Joint Physics)
  • Nipple clipping prevention for clothing profiles (Clothing -> Morph Adjustments)
  • Full atom scale support - use with tiny and giant models
  • Rotation inertia parameter
  • Calibration result caching, and unified and improved calibration
  • Fixes/QOL
  • ... and more! See the update notes for details
Naturalis is a natural behavior plugin for breasts and glutes, combining TittyMagic and BootyMagic into a single package. It automatically controls physics parameters, colliders, morphs and more, and unlocks customization of physics far beyond what is possible in VAM by default. BootyMagic only works on female person atoms.

Basic Usage

Add Naturalis.cslist to a Person atom. If needed, adjust softness and quickness or other parameters to your liking and click to calibrate the plugin.

ℹ Naturalis v1.3 requires VAM version 1.20 or newer. In addition, using the auto-update scripts requires VAM version 1.20.77.13 or newer.

Documentation


Features

Naturalis controls breast and glute physics parameters, morphs and colliders automatically.

The automatic adjustments have been carefully fine tuned with each other so that the resulting behavior for different softness and quickness values makes sense for a wide range of breast and glute sizes.

In addition to automatic adjustments, there's a lot that can be manually configured and fine tuned.
  • Automatic breast and glute physics/behavior based on softness, quickness and mass
  • Additional joint physics parameters exposed for adjustment
  • Fine grained, gradient based control of soft physics parameters
  • Adjustment of breast sag using a base angle parameter (exists for glutes as well)
  • Dynamic adjustment of soft physics based on local skin stretching and compression
  • Dynamic morphing of breasts and glutes
  • Adjustment of physics with pose to simulate the effect of gravity
  • Optimized and configurable hard colliders
  • Adaptively adjusting collider friction based on skin gloss
  • Visualization for physics gradient, local distortion physics, hard colliders and soft colliders
  • etc.
For information about clothing adjustment profiles, see the v1.1 early access update post and the documentation.

Known Issues

Issue
Comment
Reloading packages or enabling/disabling some package in Package Manager can cause morphing to stop working. Workaround: reload the plugin.TBD
Adjusting Gravity in the Scene Misc settings is not fully supportedProbably full support in v1.4

Previous Versions

  • Improved hard colliders: better and more precise positions and sizes with much less clipping, improved friction, adjustable depth from skin surface, adjustable collider spring and damper, new default settings
  • Counter sag with morphs to keep the originally intended breast shape using the Joint Base Angle parameter. The parameter is applied automatically and can be offset manually.
  • New defaults for breast joint physics settings, an incremental improvement to realism
  • Joint Angle Limit parameters that are calibrated to different breast sizes and softness values and can be offset manually
  • Fixes/QOL - see update post
  • A comprehensive clothing adjustment system for breasts and glutes
  • Improved physics and customization of gravity
  • Simulation of gravity in different directions
  • Futa breast soft physics and hard colliders
  • Improvements to morphing
  • Various quality of life improvements and fixes
  • Soft physics gradient - adjust soft physics values smoothly along a curve from outer edge to center of breast
  • Local distortion physics - enable soft physics to respond to local stretching and distortion, individually for every soft joint
  • All new calibration system which is more accurate and convenient
  • Improved softness and quickness implementations
  • Physics parameters, morphs, and collider properties fine tuned to produce better overall behavior
  • Behavior is separately optimized for disabled vs. enabled soft physics
  • Apply countergravity to glute joint to produce lift without losing inertia
  • Adjust the effect gravity on breast physics individually for each physics parameter
  • Save and load presets in-plugin
  • Save global user preferences
  • Calibration data is stored in scene JSON, preventing a calibration freeze when the scene is loaded
  • Various usability improvements and bug fixes

Incredible pluggin. Great job everlaster.

Forgot to rate this essential plugin.
The clothing options are incredible. Being able to customize how a top applies pressure completely changes the dynamics of a look.
Also possible to achieve some slow-motion-like jiggling through the many options. Just great.

Absolutely amazing plugin. It's as much of a staple as timeline or embody.
If you don't like tits this isn't for you but who are you kidding?
