Cell Fracture Modifier v1.1 for Blender – The Ultimate Procedural Shattering & Destruction Tool

Versions:  v1.1

File Size: 200 KB

Download Cell Fracture Modifier v1.1 for Blender on Windows and Mac, a powerful non-destructive addon that instantly breaks any mesh into realistic convex shards using Voronoi cell decomposition. With adjustable crack patterns, source point control, and seamless integration with Blender’s rigid body physics, Cell Fracture Modifier transforms how you create destruction effects, eliminating the need for manual boolean operations or pre-baked simulations.

Key Features of Cell Fracture Modifier v1.1:

Procedural Voronoi Fracturing: Generates complex, organic crack patterns based on mathematical cell structures, ensuring every break looks unique and natural without repeating textures

Non-Destructive Workflow: Applies fracturing as a live modifier, allowing you to tweak cell count, randomness, and recursion depth at any time before committing to final geometry

Smart Source Points: Automatically distributes fracture seeds based on volume, surface area, or vertex groups, giving you precise control over where large or small shards form

Interior Material Support: Automatically assigns a secondary material to the newly created inner faces of the shards, perfect for simulating concrete cores, wood grain, or broken glass edges

Physics Ready Output: Instantly converts fractured pieces into active rigid bodies with correct mass and collision shapes, ready to drop, explode, or shatter in real-time simulations

Recursive Sub-Fracturing: Option to sub-divide large cells further for ultra-high-detail debris, ideal for close-up slow-motion destruction shots

Custom Crack Width: Adjustable gap between shards to simulate material expansion or dust accumulation before the object even breaks

Improved Stability v1.1: Faster calculation engine for high-cell counts (1000+), better handling of non-manifold geometry, and optimized memory usage for large-scale destruction scenes

Cross-Platform Support: Works flawlessly on both Windows and Mac systems including Apple Silicon M1/M2/M3 chips

Perfect For:

VFX artists creating building collapses, exploding vehicles, and smashing props for film and games

Game developers generating low-poly destructible assets for real-time engines

Motion designers animating abstract shattering transitions for logos and titles

Architectural visualizers demonstrating structural failure or demolition sequences

Anyone tired of manually boolean-cutting objects to simulate breaks

System Requirements:

Blender 3.6, 4.0, 4.1, 4.2, 4.3+ (Latest LTS recommended)

Windows 10/11 (64-bit) or macOS 10.15+

8GB RAM minimum (16GB+ recommended for high-cell count simulations)

Rigid Body World enabled for dynamic simulations

Installation:
Open Blender and go to Edit > Preferences > Add-ons:

Click “Install…” and select the downloaded .zip file for Cell Fracture Modifier

Enable the checkbox next to “Mesh: Cell Fracture Modifier”

Access via the Object Context Menu > Cell Fracture or the 3D Viewport Sidebar (N-panel) > Cell Fracture Tab

Note: Version 1.1 introduces a new “Weak Point” feature that allows you to paint areas on the mesh where cracks are more likely to originate, giving artists directional control over how an object shatters under impact.

How to use:
Append the Cell Fracture nodegroup to your scene and use it on an object

Cell Generation: Set to Mesh Boolean if a the Voronoi Cells should be intersected with the input mesh. If set to Convex Hull the whole mesh will be treated as such

Count: Number of initial Points per Mesh Island per Recursion
Gap: Additional gap between each voronoi cell

Scale: Scale which will be applied before and after cell fracturing (can be used to create splinters)

Seed: Seed for the random position of the cells
Proximity – Curves: Curve object for the proximity of the points

Proximity – Factor: Moves the random points closer to the nearest evaluated curve point (useful for glass shattering)

Recursion – Iterations: Number of Iterations of the Cell Fracture algorithm
Recursion – Probability: Random Probability if a Mesh Island should be fractured again

Recursion – Seed: Seed for Probability
Boolean Options: Same as in the Mesh Boolean node 5
Optimizations – Triangulate: Triangulates the mesh before fracturing it (useful on flat shaded meshes with quads or n-gons to avoid visual artifacts)
Optimizations – Auto Convex Hull: Will automatically switch to Convex Hull Cell Generation if Mesh Boolean is activated but the mesh is convex
Optimizations – Delete Outside Points: Deletes all points that are outside of the input mesh
Optimizations – Interior Attribute: Creates a “inside” attribute for every face that was created from the Voronoi Fracture

Optimizations – Separate Islands: Separates the Mesh Islands on the first Recursion Iteration. Set to False if you have a closed mesh with wall thickness
