sBoolean
Boolean operations for Shape paths
Combines Shape paths with union, subtract, intersect and related Boolean operations before they are rasterized.
sBoolean
DaVinci Resolve · Fusion
sBoolean works in Fusion's vector Shape system. It lets you construct complex outlines from simpler shapes while keeping the result procedural and resolution-independent until sRender.
Overview
What sBoolean does
sBoolean works in Fusion's vector Shape system. It lets you construct complex outlines from simpler shapes while keeping the result procedural and resolution-independent until sRender.
Mental model
Think of it as vector geometry math: one shape can be added to, cut from or intersected with another shape.
Common uses
Cut holes in vector shapes
Combine title elements
Create custom badges and icons
Build procedural mattes
Construct complex paths from primitives
Prepare vector graphics for sRender

Shape Output

Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Operation — Intersection
Keeps only the area shared by all connected Shape inputs.
Operation — Union
Combines the connected Shape inputs into one unified shape.
Operation — Subtract
Selects or adjusts the Operation — Subtract behavior.
Operation — Xor
Keeps only areas that do not overlap between the connected shapes.
Style Mode
Selects the Style Mode used by sBoolean.
Style Mode — Replace / Keep
Chooses whether the Boolean result receives a new style or preserves the incoming Shape style.
Color
Sets the color.
Red / Green / Blue
Sets the RGB color of the Shape Boolean result.
Use channel-specific controls when the operation should not affect all components equally.
Alpha
Adjusts the alpha channel.
Use channel-specific controls when the operation should not affect all components equally.
Opacity
Sets the overall opacity of the material or object.
Allow Combining
Keeps the Boolean Shape result compatible with further Shape-combining operations.
Practical setup
A reliable workflow
- 1
Create two Shape branches.
- 2
Connect them to the A and B inputs.
- 3
Choose the Boolean operation.
- 4
Inspect the vector result before rendering.
- 5
Send the result to sRender or continue with other Shape operators.

Troubleshooting
Common mistakes
Using raster masks instead of Shape streams
Reversing A and B in Subtract mode
Rendering each primitive separately before the Boolean operation
Creating unnecessarily complex source paths
Production notes
Practical tips
Do Boolean work before sRender to preserve vector quality.
Name branches by role when several Boolean stages are chained.
Use simple primitives whenever possible.
