SDFusion pairs an SDF-like layer workflow with automated modifier setup and a bundled cutter-cycling tool, keeping Boolean-heavy modeling organised from block-out to finalization.
SDFusion brings a non-destructive approach to Boolean operations in Blender, built around a Signed Distance Field-like workflow. A one-click setup automatically configures Boolean, Remesh, and Smoothing modifiers in the optimal order, so no manual arrangement is needed. Boolean operations are organised through clearly named collections such as ADD-1 and SUB-1, with dedicated buttons in the SDFusion panel to assign objects. You can add further layers at any time with the "Add Layer" button, keeping experimentation open.
Real-time adjustments cover remeshing, smoothing, sharpness, and edge angle through geometry node controls in the sidebar, with live previews and support for mesh reduction. An asset library integration lets you install the included cutter asset package through a dedicated UI to use the latest procedural cutters. When a project is complete, you can apply all modifiers, perform mesh decimation, and clean up cutter objects and collections in a single step.
The add-on also bundles Collection Object Walker, an auxiliary tool that cycles through objects in a collection sequentially, one at a time, for previewing Boolean cutters. SDFusion is compatible with Blender 4.5 and later, and a native SDF node version for Blender 5.0 is included.
Sdfusion | Sdf Modeling Assistance Using Hierarchical Boolean Operations is best for blender artists doing non-destructive Boolean modeling, from rapid prototyping to final mesh creation.
Sdfusion | Sdf Modeling Assistance Using Hierarchical Boolean Operations is completely free to download and use.
SDFusion is compatible with Blender 4.5 and later versions. The package also includes a native SDF node supported version for Blender 5.0, provided in a file named SDFusion_SDF_1_0_1.zip, with further details planned in future updates. If you are on a recent Blender release, check the developer's page and the official documentation to confirm which version matches your setup before installing.
SDFusion installs as a Blender add-on, after which you access the "SDFusion" panel in the 3D View sidebar via the N key. To set up assets, go to Preferences, choose "Install Assets," select the latest Cutter_asset_X_Y.zip package, and pick an installation directory. This lets you use the latest procedural cutters through a dedicated UI, and the same flow handles updates for newer asset libraries. Detailed steps are covered in the official documentation.
SDFusion follows a non-destructive workflow. When you click "Reset Booleans & Collections" to auto-configure modifiers and collections, the original object is preserved and a working copy is created for you to build on. You can stack ADD and SUB layers, add new layers at any time, and experiment freely. When finished, "Apply All" finalizes the result with mesh decimation and "Cleanup All" removes temporary data to keep the project organised.
SDFusion is listed as free in this catalog. Because licensing terms can change over time, check the developer's page for the current details before you rely on it in a project. The download includes the main add-on, the native SDF node version for Blender 5.0, cutter asset packages, and the bundled Collection Object Walker auxiliary tool, along with links to the official documentation.
