PhysioBrush: Procedural Bone Physics & Jiggle Generator

Turn any bone-free model or with armature into a dynamic Skinned Mesh with physics in seconds! Just paint over the mesh in Unity, and Physio Brush auto-generates the bone chain, skin weights, and physics joints. Forget Blender and tedious manual rigging—adding life to hair, tails, or clothes has never been this fast and easy. -> Check the second one video :) ( and the first one)

PhysioBrush - Professional Physics Painting Solution

Stop Rigging. Start Painting.

PhysioBrush is a revolutionary tool for Unity developers that turns the tedious process of rigging hair, tails, and dynamic accessories into a fast, artistic workflow. Instead of manually placing bones and configuring joints, simply paint the desired physics areas directly on your mesh.

PhysioBrush analyzes your mesh volume and automatically generates a high-performance physical bone structure that integrates perfectly with your character.

🌟 Key Features

• Artist-Friendly Painting: Use the intuitive brush tool to define physics influence. No more fighting with vertex weight tables!
• Instant Bone Generation: Automatically creates optimized bone chains with pre-configured joints and rigidbodies based on your painted weights.
• Centroid Slicing Algorithm: Advanced volume analysis ensures bones are placed perfectly in the center of your mesh (ideal for thick tails and braids).
• 4 Specialized Physics Types:Hair: Lightweight chains for strands and ponytails.
  Tail: Heavy-momentum physics for smooth, organic tail movement.
  Jiggle: Simple 2-bone spring physics for muscles and accessories.
  Cloth (Bone-Based): A high-performance alternative to traditional cloth simulation, offering better stability and rig integration.
  
• Auto-Collision Generator: Automatically generates limb and body colliders by analyzing your character's original rig weights.
• Non-Destructive Workflow: Change parent bones, adjust curvature, or refine painting at any time without breaking your setup.

🚀 Technical Excellence

• Multi-Pipeline Support: Fully compatible with Built-in, URP, and HDRP.
• SRP Agnostic: Custom shaders ensure consistent visual feedback across all render pipelines.
• High Performance: Optimized bone-based engine that handles hundreds of dynamic strands with minimal CPU impact.
• Prefab Friendly: Easily share settings across multiple characters or create unique variations using ScriptableObject-based presets.
• Stability First: Built-in protection against mesh "exploding," hierarchy desync, and jitter.

📦 What’s in the Box?
