TruePhysbones

Live PhysBone Preview in Edit Mode
See exactly how your PhysBones will move, without entering Play mode. Tune pull, spring, stiffness, gravity, limits and per-bone curves while a faithful simulation of your actual bone chains reacts in real time, and watch your clothes and hair move with it.

Preview everywhere you work

• Inspector preview: a live 3D viewport right under the VRCPhysBone inspector. Drag a slider or a curve key and the motion changes instantly.
• Scene preview: the same simulation drawn over your avatar in the Scene view. Drag the avatar around and the chains trail, swing and settle.
• Live Mesh Preview: the real mesh moves with the simulation. Skirts, hair, clothing and accessories move in the Scene view before you press Play, even when several PhysBones drive one mesh. Nothing on your avatar is changed.

Testing, testing, testing

• Grab and pose chains the way you would in game, with angle limits and stretch. Release with Pose on and the chain holds its shape.
• Grab the preview joints directly in the Scene view.
• Looping test motions: sway, gust, circle and drop.
• NEW: set test motions to move the whole avatar and they become a walk, so you can see which chains stay put, just like in game.
• NEW: preview at the frame rate of a VR headset (72, 90, 120 or 144 Hz). PhysBones can move slightly differently there than at 60 Hz on desktop.
• Play any AnimationClip in edit mode and watch hair and skirts react to the actual dance or walk.
• Live animator outputs: _Angle, _Stretch, _Squish, _IsGrabbed and _IsPosed update every frame. No more wiring parameter-driven effects blind.
• Edit Pull, Spring, Stiffness, Gravity, Immobile and other per-bone curves in a familiar Unity-style curve editor right under the preview. It shows exactly where each bone reads the curve.
• Preview the colliders assigned to each PhysBone. You can also add a temporary test collider and move it around the Scene view without adding anything to your avatar.
• Freeze a baseline to compare against, show tip trails, and pause to step one frame at a time.

It covers:

• PhysBone versions 1.0 and 1.1
• Simplified and Advanced integration
• limits, collisions, stretching, squishing, grabbing, posing and animated transforms

Requirements
Unity 2022.3 · VRChat Avatars SDK 3.10.4 or newer (tested with 3.10.5)

How do I report issues?
The purchase note in your Jinxxy inventory explains how to report bugs.

Will the add-on be supported with updates and bug fixes?
TruePhysBones will get long-term support for the foreseeable future. It will be ported to Unity 6 when VRChat releases a compatible SDK, and existing customers won't pay again for the Unity 6 version.
