O'Explosion

Designed for motion graphics and abstract animations, this tool allows you to create complex, multi-phase explosion effects using object instancing and precise timeline control.

• Directional Control: Choose the primary axis of explosion (+X, -X, +Y, -Y, +Z, -Z).
• Two-Phase Animation: * Phase 1 (Exit): Strict linear clearance to prevent intersecting geometry.
  • Phase 2 (Chaos): Procedural scattering with randomized rotation and scaling.
• Instance & Modifier Support: Automatically duplicates source objects along with their entire modifier stack (Bevel, Subdivision, etc.) while sharing mesh data to save memory.
• Organic Layer Start: Option to randomize the starting order of objects within the same coordinate plane for a more natural, wave-like effect.
• Smart Timeline Management: Automatically clears old animation data upon regeneration and adjusts the scene's end frame to match the final keyframe of the explosion.
• Built-in Debugger: Includes standard O'-series alert and file log debuggers for stable operation.

Since this add-on uses the modern Blender 4.2+ Extension format:

1. Download the O_Explosion_Pro.zip file.
2. Open Blender and navigate to Edit > Preferences > Add-ons.
3. Click the drop-down menu in the top right corner and select Install from Disk....
4. Locate your downloaded .zip file and select it.
5. Enable the extension in the list.

1. Create your base geometry (donors) and place them into a specific Collection (e.g., "Source_Debris").
2. Open the 3D Viewport and press N to open the side panel.
3. Navigate to the O'Explosion tab.
4. In the Source Collection field, select your prepared collection.
5. Configure the Grid Layout to set the initial array dimensions and spacing.
6. Adjust Phase 1: Exit settings to determine how far and how long the objects travel linearly before exploding.
7. Adjust Phase 2: Chaos settings to set the explosion force, spread, and random scale boundaries.
8. Click GENERATE & CLEANUP.

The script will automatically generate the instances, apply the keyframes, and update your timeline. If you want to change the parameters, simply adjust the sliders and click generate again — the old explosion will be cleanly removed.

• Blender 4.2.0 or newer.
