PolyTools earns its place in the superhive library for keeping retopology inside the 3D Viewport, with a sub-mode workflow that separates building, looping, deleting, and merging.
PolyTools brings retopology into the Blender 3D Viewport, letting you build clean quad-based meshes through a focused set of sub-modes. The workflow moves through building, looping, refining, and cleaning, so you can create quads, place guide points, draw loops, delete geometry, and tweak vertices without leaving the viewport.
Quad Mode offers a smart live quad preview, guide points placed with Ctrl + LMB, drag-to-create quad strips, and adaptive spacing based on local edge length. Loop Mode draws clean edge loops on curved cylindrical surfaces with an adjustable segment count, useful for limbs, pipes, openings, and rounded forms. Delete Mode uses brush-style deletion for faces, vertices, or full edge loops, while the Tweak and Smart Merge tools move any vertex or guide point and merge nearby vertices to close gaps and clean poles.
Hotkeys cover each mode and action, from Q, L, and X to switch modes to S + drag for loop segments. PolyTools is designed for Blender 5.0 to 5.1, ships under a GPL license, and includes documentation.
Polytools is best for blender artists building clean quad-based topology in the 3D Viewport, including cylindrical and rounded forms such as limbs, pipes, and openings.
Polytools is completely free to download and use.
PolyTools is designed for Blender 5.0 to 5.1, working inside the 3D Viewport for retopology. Within that range, the add-on's build, loop, refine, and clean sub-modes run directly in the viewport as you shape quad-based meshes. Compatibility outside those versions isn't stated on the developer's page, so if you run an older or newer Blender release, check the developer's page for details before installing. The listed range is the version window to rely on.
PolyTools maps its workflow to hotkeys, so switching tools stays on the keyboard. Press Q for Quad mode, L for Loop mode, and X for Delete mode. Ctrl + LMB places a guide point, RMB removes one, and an LMB drag draws a quad strip. Holding Shift triggers Smart Merge, S + drag adjusts loop segments, and F, V, or E set the delete target for faces, vertices, or edge loops. ESC exits. These shortcuts cover building, looping, deleting, and merging without leaving the viewport.
PolyTools ships under a GPL license, according to the developer's page. GPL is a common open-source license across Blender add-ons, and it governs how you can use, modify, and redistribute the code. For the specific terms that apply to your use, and for any conditions the developer attaches, review the license and the details listed on the developer's page. A support email is listed with the product for any licensing questions.
PolyTools is listed as free in this catalog. Pricing and licensing can change over time, so for the current terms and any download conditions, check the developer's page directly. The add-on is distributed under a GPL license, which covers use and redistribution of the code. If you need clarification on what's included or how to obtain the latest version, the developer's page is the place to confirm before you download.
