"Making VRC avatars in Blender is great, but setting up bones for bouncy physics mesh is pure PAIN." "I've suffered through Armature torture for too long—let TECHNOLOGY save us!!!" "Me, a beginner 3D artist, hitting a wall at bone & weight painting setup and literally dying." If you can relate to any of these, this Blender addon is here to rescue you! ◆ TL;DR A Blender addon designed for VRC PhysBones that automatically generates bone chains and weight paint on your Armature—just by selecting the mesh vertices of the skirt or scarf you want to wiggle! ◆ What is PhysBone AutoRig? PhysBone AutoRig is a simple, delightfully handy Blender addon. When making costume models, it automates the tedious Armature bone and weight setup required to apply VRChat’s PhysBone collision system to dynamic items like skirts and scarves. ◆ Features One-Click Auto Generation: Select the mesh vertices you want to animate in Blender, and the addon automatically analyzes the geometry, adding bone chains and weight settings to your Armature based on your setup. (Basically, it handles all the tedious Blender-side prep work required for PhysBones for you!) Plug & Play in Unity: Attach a PhysBone component to the parent bone in Unity, and you're good to go instantly! Non-Destructive Workflow: Full Ctrl + Z undo support. Tweak settings and regenerate as many times as you like without stress. *v1 includes dedicated Skirt and Scarf modes. Scarf mode can also be used for ribbons, ties, strings, tails, and more. (Note: Scarf mode is currently in Beta, so it might be a bit experimental!) ◆ How to Use Open your clothing or accessory model in Blender. Prepare an Armature modifier. Select the mesh vertices you want to animate. Open PhysBone from the N-panel (sidebar), configure your settings, and hit Generate. A task that used to take dozens of minutes (or hours!) and trip up beginner modellers can now be done by anyone in just a few minutes. (TIPS: Rumor has it Alt + Shift + Left Click on an edge selects an entire loop ❓) (TIPS: Rumor has it Ctrl + Shift + Left Click on a vertex selects a rectangular area from start to end ❓) *While it works out of the box, we recommend fine-tuning your mesh shape and PhysBone settings prior to generating. ◆ Supported Versions Tested & Confirmed: Blender 4.1, 4.2 LTS, 4.5 LTS Theoretically compatible with: 3.6 LTS, 4.0, 4.3, 4.4.
