PHYSICS DROPPER - Easy Rigidbody & Cloth Physics Simulation for Blender
═════════════════════════════════════════════════════════════════════

Transform complex physics simulations into simple one-click operations. Physics Dropper makes professional-quality rigid body and cloth simulations accessible to everyone - from beginners to advanced users.

Stop wrestling with Blender's physics settings. Physics Dropper gives you:

✓ ONE-CLICK PHYSICS SETUP - Just select, press V, and watch it work
✓ MATERIAL PRESETS - Cotton, Denim, Leather, Rubber, Silk - perfectly tuned
✓ INTERACTIVE FORCE FIELDS - Place forces in real-time with mouse and scroll wheel
✓ HIGH-POLY OPTIMIZATION - Automatic proxy creation for heavy meshes
✓ EARTHQUAKE EFFECTS - Add procedural shake to any simulation
✓ SMART BAKING - Convert physics to keyframes with one click
✓ COLLECTION SUPPORT - Apply physics to entire collections instantly

You can grab the full version HERE for free.
But if you are in a donation mood, and you like to support me and the Blender development fund, then you can buy the addon. 😊

KEY FEATURES
═════════════════════════════════════════════════════════════════════

🎯 RIGID BODY PHYSICS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Quick Setup: Apply active or passive physics with a single click
• 8 Collision Shapes: Convex Hull, Mesh, Box, Sphere, Capsule, Cylinder, Cone, Compound
• Fine-Tuned Control: Mass, friction, bounciness, damping, collision margins
• Proxy System: Automatic voxel remeshing or decimation for high-poly objects
• Performance: Optimized for both real-time preview and final rendering





🌍 EARTHQUAKE SYSTEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Procedural World Shake: Dynamic motion for all active physics objects
• Per-Axis Control: Enable/disable X, Y, Z independently
• Adjustable Intensity: 0-100% for subtle vibrations to extreme chaos
• Non-Destructive: Uses F-curve modifiers - easily editable
• Bake-Ready: Preserves in final keyframe baking




🧵 CLOTH SIMULATION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Material Presets: Pre-configured settings for realistic fabric behavior
  - Cotton: General purpose, natural drape
  - Denim: Stiff, heavy fabric
  - Leather: Thick, resistant material
  - Rubber: Stretchy, elastic behavior
  - Silk: Light, flowing, luxurious

• Advanced Controls:
  - Stiffness: Tension, compression, shear, and bending
  - Internal Springs: Soft body-like volume preservation
  - Pressure: Perfect for inflatable objects (balloons, cushions)
  - Self-Collision: Prevents cloth from passing through itself
  - Air Viscosity: Natural air resistance
  - Collision Fatten: Automatic thickness for collision objects




⚡ INTERACTIVE FORCE FIELDS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Modal Force Mode (F key): Revolutionary real-time force placement
  - Move mouse to position in 3D space
  - Scroll wheel to adjust force radius
  - Ctrl+Click for precision surface snapping
  - Visual sphere shows force area

💾 SMART BAKING SYSTEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Intelligent Range: Only bakes up to current timeline position
• Preserves Effects: Keeps earthquake and force field results
• Auto Cleanup: Removes physics modifiers, keeps keyframes
• Workflow: Play → Pause → Bake → Done

🎛️ COLLECTION INSTANCE SUPPORT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Apply physics to entire collections at once
• Perfect for scattered objects, particle replacements, geometry nodes
• Maintains hierarchy and organization
• Mix active and passive objects intelligently

KEYBOARD SHORTCUTS
═════════════════════════════════════════════════════════════════════

V          →  Apply physics to selection
Shift+V    →  Finalize and bake simulation
F          →  Enter interactive force field mode

All shortcuts are fully customizable in Blender Preferences.

TIPS & BEST PRACTICES
═════════════════════════════════════════════════════════════════════

PERFORMANCE:
✓ Enable proxy for meshes over 10,000 polygons
✓ Start with low substeps (3-5) for preview
✓ Increase quality only for final render
✓ Bake long simulations to keyframes

STABILITY:
✓ Use Split Impulse to reduce jittering
✓ Increase Solver Iterations if objects pass through
✓ Add more Substeps for fast-moving objects
✓ Start with low force values, increase gradually

CLOTH TIPS:
✓ Always have collision objects (floor, body, etc.)
✓ Enable Self Collision for complex folds
✓ Use Pin Group (vertex group) to anchor cloth edges
✓ Increase Collision Quality if penetration occurs

═════════════════════════════════════════════════════════════════════
INSTALLATION
═════════════════════════════════════════════════════════════════════

1. Download physics_dropper.zip
2. Open Blender → Edit → Preferences → Extensions
3. Click "Install from Disk"
4. Select downloaded ZIP file
5. Enable "Physics Dropper"
6. Access from 3D Viewport sidebar (press N) → PhyDrop tab

Done! Start simulating in seconds.

═════════════════════════════════════════════════════════════════════
FINAL NOTES
═════════════════════════════════════════════════════════════════════

Physics Dropper is designed with one goal: place those fricking assets quickly!
But at the end it developed into so much more.

Whether you're dropping a thousand objects (if you PC can handle that), draping silk over furniture, Physics Dropper handles it with ease.

Stop fighting with physics settings. Start creating.

Made with ❤️ for the Blender community.

VERSION HISTORY
═════════════════════════════════════════════════════════════════════


Version 1.4.1 (Current)
• Rigid bodies already on your objects are saved, removed for a clean setup, and
  restored exactly on Apply or Reset
• Drops survive a save, a reload, an undo or a crash - nothing is left welded to
  your objects, and a file saved mid-simulation reopens ready to Apply
• Generated colliders no longer inherit stray settings from the meshes they were
  built from, which could produce a collider that collided with nothing
• New "Clear All Rigid Bodies" option in World Settings
• Exit Drop Mode now cleans up instead of leaving the collider behind
• Scenes that do not start at frame 1 keep their frame range
• A failed Drop rolls the scene back instead of leaving it stuck in drop mode
• Cloth: rigid bodies in the scene no longer keep falling during a cloth drop -
  they are saved, frozen and restored just like in a rigidbody drop
• Cloth: collision already on the collider sources no longer silently overrides
  your World Collision Settings
• The Colliders selector now sits directly above the Drop button in both modes
• Fixed: the Remove Simple Force button never appeared
• Blender 4.2 - 5.2 compatibility

Version 1.4.0
• Added a Colliders selector (Auto / List / None)
• Collider list with Add Selected / Add Collection / Remove / Select / Clear
• Hidden objects and objects in excluded collections usable as colliders,
  without ever being unhidden
• Current collider mode shown above the Drop button
• Drop warns when no collider will be generated and nothing is collidable


Version 1.3.0
• Migrated to Blender 4.5+ extension format
• Added collection instance support for physics
• Enhanced force mode with Ctrl+Click surface snapping
• Improved keyframe baking system
