Boolean Pro

Boolean Pro is designed to act as a replacement for Blender's built-in boolean modifier, and provides extra functionality. For reference, documentation for Blender's built-in modifier can be found here.

Add-on

The normalMagic Add-on includes operators to quickly set up the Boolean Pro modifier, similar to the Bool Tool add-on.

The most powerful feature is transferring the normals automatically from boolean inputs for perfect boolean normals:

The cutter object can be given an outset (expanded) with even thickness before cutting:

There is also a Slice operation with optional inset:

Intersect	Union	Difference	Slice

Options

Main

• Operation: Which boolean operation to perform.
  • Intersect: Keep the part of the mesh that is shared between inputs.
  • Union: Combine input meshes into a single mesh.
  • Difference: (Default) Subtract input meshes from source mesh.
  • Slice: Slice source mesh with input meshes. This combines "Intersect" and "Difference" into the same output.
• Object: Mesh object to use for boolean operation.
• Collection: Collection containing mesh objects to use for boolean operation.
• Solver:
  • Float: Simple solver with good performance.
  • Exact: Slower solver with best results on coplanar faces.
  • Manifold: (Default) Fastest solver that only works on manifold meshes, but gives better results.
• Outset: Expands the cutter mesh with even thickness.
• Inset (Slice Mode): Offsets the cutter inwards for the intersect boolean to give a gap between meshes.

Weld

• Merge by Distance: Merge vertices based on distance.
• Distance: Distance at which to merge vertices.

Shading

• Materials: How to assign materials to new faces.
  • Index Based: Match material index from boolean meshes.
  • Specify: Specify a material to apply to all new faces.
  • Transfer: Transfer materials from boolean meshes. This might not be accurate when using collections.
• Transfer Normals: Use normals from input meshes. Produces the best normals.
• Mark Sharp: Mark all intersection edges between meshes as sharp.

Solver Options

• Result: Whether to output a solid object or a cut surface.
  • Solid: Output full Boolean result.
  • Surface: Output a cut surface with open edges where new faces would appear.
• Sequential (Float solver only): Perform Booleans one mesh island at a time. This often gives better results but can be slower.
• Self Intersection (Exact solver only): Correctly calculates cases when one or both operands have self-intersections. This involves more calculations making the node slower.
• Hole Tolerant: Optimizes the Boolean output for non-manifold geometry at the cost of increased computational time. Because of the performance impact, this option should only be enabled when the solver demonstrates errors with non-manifold geometry.
