RetopoFlow is a Blender add-on that provides sketch-based retopology tools for generating low-poly geometry that snaps to high-poly surfaces as you draw.

The tool solves the retopology problem—the need to create clean, animation-ready geometry from high-resolution sculpts or scans—by offering an interactive drawing workflow. As you sketch on the surface of a high-poly object, the geometry automatically snaps to follow that surface, eliminating the manual vertex placement that traditional retopology requires. The suite includes multiple specialized tools designed to handle different retopology scenarios through this unified sketch-based approach.

RetopoFlow suits artists working in Blender who need to convert detailed sculpts or photogrammetry into production-ready models. It is particularly valuable for character artists, hard-surface modelers, and anyone moving between sculpting and animation pipelines. The tool works across all operating systems that Blender supports and maintains compatibility with multiple Blender versions through different releases of the add-on.

Development on the project shows consistent maintenance aligned with Blender's release cycle, with versions tracking Blender's major updates to ensure compatibility. The codebase is open source under the GPL 3.0 license, though non-code assets remain proprietary. The project maintains active documentation covering installation, quick-start guidance, and detailed feature documentation, indicating ongoing attention to user onboarding and support.
