VoroFX

Procedural Fracturing for Blender

Create, direct, and simulate destruction without a complicated workflow. VoroFX combines a procedural Geometry Nodes fracture system with Blender's rigid body physics to take an object from intact mesh to simulated destruction in just a few steps.

MAIN OVERVIEW

SIMPLE WORKFLOW

Fracture. Confirm. Simulate.

01 — Fracture → 02 — Confirm → 03 — Physics → 04 — Constraints → 05 — Destroy

PROCEDURAL WORKFLOW

Procedural Voronoi Fracturing

Start with your mesh and create a procedural Voronoi fracture directly through Geometry Nodes. Because the fracture remains procedural before confirmation, you can continue adjusting the pattern before committing it to individual shards.

• Procedural Voronoi fracture generation
• Adjustable fracture count
• Randomized fracture patterns
• Non-destructive setup before confirmation
• Fracture gap control
• Fast rebuild workflow

PROCEDURAL FRACTURE

See changes in real-time, no need to wait.

ART DIRECTION

Direct Fractures with Guide Curves

Destruction doesn't always need to be completely random. VoroFX includes a Guide Curve workflow that lets you influence where fracture detail is concentrated.

Draw directly in the scene, edit the guide, and use it to art-direct the fracture pattern. Concentrate detail around important areas without increasing fracture density across the entire object.

ART-DIRECTED DESTRUCTION

Use procedural controls for the overall fracture while guide curves direct additional detail exactly where you want it.

GUIDE CURVE FRACTURING

Control where fracture detail appears.

WHEN YOU'RE READY

✓ Confirm the Fracture

Keep experimenting while the fracture is procedural. Once you're happy with the result, simply press Confirm.

VoroFX automatically:

✓ Applies the procedural fracture

✓ Separates the pieces into real shard objects

✓ Sets shard origins

✓ Creates a managed VoroFX fracture group

CONFIRM WORKFLOW

Procedural fracture can become real individual shards. Ready to simulate.

BLENDER PHYSICS

Built Around Blender Rigid Bodies

VoroFX turns confirmed fracture pieces into standard Blender rigid bodies, allowing your destruction setup to work with Blender's familiar physics system.

Physics Controls

• Mass

• Collision Shape

• Friction

• Bounciness

• Linear Damping

• Angular Damping

• Deactivation

• Collision Margins

SELECTION OR ENTIRE GROUP

Apply physics to the entire active fracture group or only the shards you currently have selected.

RIGID BODY PHYSICS

Set up your rigid bodies instantly.

DESTRUCTION CONTROL

Automatic Breakable Constraints

Connect nearby shards using automatically generated Blender rigid body constraints. Instead of manually creating connections between fracture pieces, VoroFX analyzes the active fracture group and builds them for you.

• Constraint type
• Connection distance
• Maximum neighbors per shard
• Breakable constraints
• Breaking threshold
• Linked collision control
• Active Group or Selected Shards targeting

BREAKABLE CONSTRAINTS

Setting up constraints has never been easy. Now it is.

ORGANIZATION

Managed Fracture Groups

VoroFX keeps converted destruction setups organized using managed fracture groups.

• Choose the active fracture group
• See shard, rigid body, and constraint counts
• Select every shard in the group
• Select generated constraints
• Rename groups
• Apply physics to an entire group
• Generate constraints for an entire group

FROM OBJECT TO DESTRUCTION

One Focused Workflow

VoroFX is designed to remove the repetitive setup normally involved in turning procedural fracture geometry into an organized rigid body destruction simulation.

Great For:

• Destruction effects

01 — GETTING STARTED

Installation

Install VoroFX like a standard Blender add-on.

Installation Steps

1. Open Blender.

2. Open Edit → Preferences → Add-ons.

3. Choose the option to install an add-on from disk.

4. Select the VoroFX add-on file.

5. Enable VoroFX if necessary.

6. Return to the 3D Viewport.

The VoroFX interface is available from the 3D Viewport Sidebar(N).

02 — QUICK START

Your First Destruction Setup

Select Mesh → Create Fracture → Adjust → ✓ Confirm → Setup Physics → Constraints  → Simulate

03 — FRACTURING

Creating a Procedural Fracture

Select the mesh you want to fracture and press Create Procedural Fracture.

VoroFX creates the fracture procedurally using Geometry Nodes. At this stage the result has not yet been converted into separate objects.

NON-DESTRUCTIVE STAGE

Experiment with the fracture before pressing Confirm. This is the best time to change the pattern and guide curve.

Fracture Controls

Use the fracture controls to shape the procedural result before confirmation.

Adjust the fracture parameters and watch the Geometry Nodes result update directly in the viewport.

New Pattern

Generate another fracture pattern without leaving the VoroFX workflow.

Rebuild

Rebuild the procedural fracture setup when needed.

Remove Fracture

Remove the procedural fracture setup before it has been confirmed.

04 — ART DIRECTION

Guide Curves

Guide Curves let you influence where additional fracture detail is concentrated.

Instead of increasing detail across the entire mesh, use a curve to direct the fracture toward the area that matters.

Draw Guide — Create the guide directly in the viewport.

Edit Guide — Modify the existing curve.

Finish Guide — Finish editing and return to the fracture workflow.

Clear Guide — Remove the current guide.

TIP

Guide curves are most useful before confirming the fracture, while the setup is still procedural.

05 — FINALIZE

✓ Confirm

Once the procedural fracture looks the way you want, enter a Group Name and press Confirm.

Confirm changes the fracture from a procedural setup into real individual shard objects that can participate in Blender physics.

Confirm automatically:

✓ Applies the fracture

✓ Separates loose pieces

✓ Creates individual shard objects

✓ Sets shard origins

✓ Creates a managed VoroFX group

IMPORTANT

Make your procedural fracture adjustments before Confirm. Confirm is the transition into the shard and physics workflow.

06 — ORGANIZATION

Fracture Groups

Confirmed shards are registered as a managed VoroFX fracture group. Groups make it easier to work with multiple destruction setups in one scene.

Group Controls

• Choose the active fracture group

• View shard count

• View rigid body count

• View constraint count

• Select all group shards

• Select group constraints

• Rename the group

07 — PHYSICS

Rigid Body Physics

VoroFX uses Blender's rigid body system for confirmed shards.

Apply Physics To

Entire Group

Setup or update physics on every shard belonging to the active fracture group.

Selected Shards

Setup or update physics only on the VoroFX shards currently selected.

Basic Physics

Mass — Controls shard mass.

08 — CONNECTIONS

Rigid Body Constraints

Constraints connect rigid-body shards together, allowing an object to remain assembled until enough force causes its connections to break.

Generate Constraints For

Active Group

Build constraints between rigid-body shards in the active VoroFX group.

Selected Shards

Build connections only between selected rigid-body shards.

Constraint Settings

Constraint Type

Select the Blender rigid body constraint type.

Connection Distance

Controls how far apart shards may be before VoroFX considers them for a connection.

Max Neighbors / Shard

Limits how many generated connections each shard can receive.

Breakable

Allows generated connections to break during the simulation.

Breaking Threshold

Controls the breaking threshold used by the generated constraints.

Disable Linked Collisions

Controls collisions between shards directly connected by a constraint.

REBUILD REQUIRED

Connection Distance and Max Neighbors affect which connections are created. Generate/Rebuild constraints after changing them.

09 — VIEWPORT DISPLAY

Constraint Helper Display

Constraint helpers can be customized independently from their underlying Bullet constraint behavior.

Display Shape

Axes, Arrows, Single Arrow, Circle, Cube, Sphere or Cone.

Display Size

Adjust the viewport size of the helper.

In Front

Draw helpers in front of scene geometry.

Show Names

Display object names in the viewport.

Hide Helpers

Hide helper objects while retaining their rigid body constraints.

APPLY SETTINGS

Display settings can be updated on existing generated helpers without rebuilding the connection network.

10 — RECOMMENDED WORKFLOW

Building a Destruction Setup

01 — FRACTURE

Select the original mesh and create a procedural fracture.

02 — ART DIRECT

Adjust the fracture and use a Guide Curve where additional detail is needed.

03 — CONFIRM

Name the fracture group and convert the procedural result into real shards.

04 — PHYSICS

Configure rigid body properties and run Setup Physics.

05 — CONSTRAINTS

Generate breakable connections if the object should initially remain assembled.

06 — SIMULATE

Play the Blender timeline and refine the physics and breaking behavior.

11 — TIPS

Getting Better Results

Stay procedural until you're satisfied.

Adjust the fracture and Guide Curve before pressing Confirm.

Use groups for complex scenes.

Separate destruction setups into clearly named fracture groups.

Use selection targeting for local changes.

You don't need to modify every shard when only part of the setup needs different physics.

Keep constraint networks reasonable.

Connection Distance and Max Neighbors determine how many links VoroFX generates.

12 — TROUBLESHOOTING

Common Questions

Why can't I set up physics yet?

The procedural fracture must first be confirmed so VoroFX has real shard objects to use for rigid body physics.

Why aren't constraints being generated?

Constraints require rigid-body shards. Make sure Physics has been set up for the target shards first.

Why did changing Connection Distance do nothing?

Connection Distance changes the generated network itself. Use Generate/Rebuild after changing it.

Can I hide the constraint helpers?

Yes. Enable Hide Helpers. The viewport helpers can be hidden while the underlying rigid body constraints remain active.

Can I apply physics to only part of the fracture?

Yes. Set Physics Target to Selected Shards and select the shards you want to modify.

VoroFX QUICK REFERENCE

Fracture → Confirm → Physics → Constraints → Simulate

Keep the fracture procedural while designing the pattern. Confirm when you're ready to create real shards, then use the Physics and Constraints sections to build the final destruction setup.
