QuadPen earns its place in the Superhive library as a focused, hotkey-driven retopology brush for Blender, with version 1.1 adding Blender 4.0 support.
QuadPen - Retopology Tool is a brush-based quad drawing add-on for Blender aimed at retopology tasks. It lets you draw and generate quads and guides automatically over an existing mesh, so you can build clean, optimized topology as you draw.
The tool centers on control over how your topology is laid out. Segment control adjusts the number of segments while drawing, and guides can be straightened or re-routed to align with your intended edge flow. A snake feature manipulates guides for organic shapes, quad relaxing redistributes quads for a more uniform surface, and quick loop cutting adds new edge loops. QuadPen runs as a modal operation driven by hotkeys: LMB draws quads, MMB sets segments, Ctrl with mouse movement changes brush size, Ctrl activates snake, Alt re-routes or straightens, Shift smart-merges, R relaxes, C loop-cuts, Z undoes and Esc exits.
Version 1.1 added Blender 4.0 support along with a GPU API fix. Documentation is available from the developer.
Quadpen - Retopology Tool is best for blender artists building clean, optimized quad topology by drawing directly over existing meshes.
Quadpen - Retopology Tool is completely free to download and use.
QuadPen added Blender 4.0 support in version 1.1, which also included a GPU API fix. The tool is presented as a brush-based quad drawing add-on built for retopology inside Blender. If you rely on a specific Blender version, check the developer's page to confirm current compatibility before installing, since supported versions can change across updates and the version 1.1 entry is the most recent detail available here.
QuadPen runs as a modal operation controlled by hotkeys. LMB draws quads, MMB sets segments and Ctrl combined with mouse movement changes brush size. Holding Ctrl activates the snake feature, Alt re-routes or straightens guides, and Shift performs smart merge. R relaxes quads, C triggers loop-cut, Z undoes and Esc exits the modal. This keeps drawing, guide manipulation and topology refinement accessible without leaving the drawing session.
QuadPen is listed as free in this catalog. Licensing terms can differ from what is shown here, so for the current price, license conditions and any usage restrictions, check the developer's page on Superhive directly. That page is also where you can find the documentation referenced for the tool, which is the best source for setup and up-to-date details before you commit to using it in a project.
