Plugins + Scripts Physics Attachment Engine

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​

1. Select Source Atom + Controller
2. Select Target Atom + Controller
3. Choose preset (Soft / Firm / Lock)

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
