The work
Exploring Physics in Blender
From fluid motion to fractured structures, BlenderPhysics explores practical simulation workflows, creative experiments, and tools that help bring complex physical effects into a shot.
-
Native Blender Tools
Explore Blender's built-in simulation systems, including rigid bodies, forces, collisions, and other physics-driven effects.
-
FLIP Fluids
Discover tutorials, techniques, and workflows for creating detailed fluid simulations with the FLIP Fluids add-on.
-
Fracture & Destruction
From the original Fracture Modifier to Refracture — an independently developed Blender add-on focused on creative control over destruction.
Refracture
Destruction that follows the shot.
Refracture is a Blender add-on for creating and directing destruction sequences. Instead of relying on a single uncontrolled collapse, artists can define how objects fracture, when pieces are released, and how destruction develops over time.
A dedicated Sequencer brings these steps together, allowing complex destruction to be planned, previewed, and adjusted directly within Blender.
Fracture. Sequence. Refine.
-
Fractured Objects
Each fractured object has its own control panel for managing shards, mass, friction, materials, and physics settings — keeping essential properties organized and accessible.
-
Smaller Shards
Control where fractures become more detailed. Use a curve, mesh, or Empty to generate smaller shards in selected areas while keeping larger fragments elsewhere.
-
Colliders & Physics Triggers
Define the objects that interact with your fractured structures, from floors and impact objects to animated characters. Use these interactions to drive physics triggers and secondary effects.
-
Clusters
Organize selected shards into groups and control their behavior and release during a destruction sequence.
-
Assembly Links
Connect multiple fractured objects into a single structure. Build assemblies such as windows within walls while keeping their individual fracture setups organized.
-
Sequencer
Design destruction step by step. Combine freeze states, clusters, paths, triggers, shockwaves, and gravity into a timed sequence that can be played, adjusted, and reset.
-
Shockwaves
Create directional or spiral shockwaves without manually drawing curves. Control how shards are released progressively across a defined frame range.
-
Post FX
Connect debris and smoke effects to your destruction sequence, triggering secondary effects when fragments are released.
-
Blockers
Use mesh volumes to influence automatically generated clusters, controlling where they stop, split, or remain separated.
Refracture is in active development.
We're currently looking for a limited number of beta testers to help evaluate the workflow, test real-world scenarios, and identify areas for improvement.
Refracture
Three Steps. One Controlled Sequence.
-
1
Prepare the Object
Create and configure the fractured objects in your Blender scene. Adjust shard properties and establish how the individual parts are organized.
-
2
Design the Destruction
Use the Sequencer to define the events that drive the destruction, including triggers, paths, shockwaves, and gravity.
-
3
Preview and Refine
Run the sequence, review the result, and adjust the timing and behavior until the destruction fits your shot.
About Refracture
What is Refracture?
Refracture is an independently developed Blender add-on for creating and directing destruction sequences through an artist-controlled workflow.
Does Refracture replace Blender's original Fracture Modifier?
No. Refracture is a separate project with its own workflow, tools, and Sequencer, designed around the needs of individual shots.
Does Refracture support fully dynamic re-fracturing?
Not currently. Refracture includes collision-driven methods for releasing connected shards, but the remaining structure is not automatically re-simulated around newly created openings. More advanced approaches remain an area of ongoing research.
When will Refracture be available?
Refracture is still under development. A public release date has not been announced.
Can I become a beta tester?
A limited beta-testing initiative is underway. If you're interested, contact BlenderPhysics with a brief description of how you would like to test Refracture.
AI & Development
Human vision. AI-assisted development.
Refracture is built on years of hands-on experience with Blender, fracturing workflows, and physics simulations. While AI-assisted coding is part of my development process, the ideas, technical concepts, and creative direction behind Refracture are my own.
Developing reliable destruction workflows in Blender comes with significant challenges. Limitations involving parenting, dependency cycles, rigid body simulations, and Blender's internal systems cannot simply be solved by asking an AI to write code.
Finding practical solutions requires a deep understanding of these limitations, countless hours of experimentation, testing, and sometimes entirely unconventional approaches.
I have programming experience myself, but I also embrace modern tools that help me turn complex ideas into working software. AI makes certain aspects of development more accessible and allows independent creators to pursue projects that might otherwise remain unrealized.
I believe this is a positive evolution in software development.
What matters to me is not whether every line of code was written manually, but whether the software solves real problems, introduces useful ideas, and delivers reliable results.
Refracture is an independent project driven by curiosity, experience, and a passion for physics-based destruction.
And I'm happy to share that journey with the Blender community.
