Physics Attachment Engine
Attach any controller to any other controller using smooth, physics-based joints.
Perfect for natural interactions like hand-to-object, body-to-body, or person-to-prop behavior.
Physics Attachment Engine connects controllers using configurable joints that fade in smoothly, stay stable, and detach cleanly. Includes a clean UI, trigger support, full scene save/load, and safe error handling.
Features
✔ Attach any controller → any controller
Works across Persons, Props, and all rigidbody-based atoms.
✔ Soft / Firm / Lock presets
Choose the physical behavior that fits your scene.
✔ Smooth fade-in & fade-out
Attach and detach feel natural — no snapping or popping.
✔ Clean UI with active attachment list
See all active connections at a glance, with individual Detach buttons and a Detach All option.
✔ Automatic validation
If a controller has no rigidbody, the plugin shows a clear error and prevents invalid attachments.
✔ Full scene save/load
All attachments restore with the scene (atoms, controllers, presets, blend speed).
✔ NEW: Trigger Support (v1.0.1)
Control the plugin from any system that supports triggers:
- PoseSaver
- LogicBricks
- Timeline
- Buttons
- Scene triggers (OnEnter / OnExit / collision)
Available actions:
- Attach – attaches with current UI selections
- Detach All
Perfect for automated interactions and pose-triggered attachments.
How to Use
- Select Source Atom + Controller
- Select Target Atom + Controller
- Choose preset (Soft / Firm / Lock)
- Adjust blend speed
- Press Attach
- Use Detach or Detach All to release
Trigger automation:
Set your atoms/controllers in the UI → call “Attach” or “Detach All” from another plugin.
Example Use Cases
- Hand → Object (cups, tools, weapons)
- Hand → Breast or Hip → Chair (natural body following)
- Person A → Person B (linked movement, interactions)
- Props following other props
- Pose → OnEnter → Auto-attach hands to a prop
- Timeline animation that dynamically attaches/detaches
Roadmap
Upcoming improvements(not decided yet):
- Limited Motion Mode (soft, realistic tether movement)
- Per-attachment strength tuning
- Advanced integration actions for Timeline & LogicBricks
