Poly Engine earns its place in the superhive library by keeping retopology inside Blender's viewport, with click-to-place verts, edge-loop previews, and an internal undo stack for free experimentation. Documentation is provided by the developer.
Poly Engine - Retopology Best Friend is a Blender add-on for building clean topology directly on a sculpt inside the viewport. You click to place verts and drag to move them, and everything sticks to the reference mesh automatically with no extra steps. Holding ALT and hovering over an edge previews exactly where a loop will land before you click.
Beyond loops, Quick Bands lays down a whole strip of quads once you click a path, while a Point Slide brush nudges existing verts around. Hold R and brush over lumpy areas to smooth them without pulling anything off the surface. Ghost symmetry lets you eyeball the X-axis without committing to it, and an internal undo stack keeps your experiments separate from Blender's history.
It works with Blender 4.0 through 5.x, ships as a Blender extension-compatible add-on, and is distributed under the GPL license.
Poly Engine - Retopology Best Friend is best for blender artists retopologizing a sculpt directly in the viewport, from placing individual verts to laying down full strips of quads.
Poly Engine - Retopology Best Friend is completely free to download and use.
Poly Engine - Retopology Best Friend supports Blender 4.0 through 5.x, with listed compatibility spanning versions 4.0 to 5.2. It ships as a Blender add-on and is marked as Blender Extension compatible, so it fits into recent releases across that range. The developer also lists render engines including Cycles, Eevee, Octane, Arnold, Blender Internal, and the Blender Game Engine alongside it. If you run a version at the edge of that range, check Gorilla Fang Studio's page to confirm the current supported builds before installing.
Poly Engine - Retopology Best Friend is listed as free here in the catalog, and it's distributed under the GPL license. For current licensing terms, any changes, or details on how the developer distributes updates, check Gorilla Fang Studio's page directly. The add-on is a Dev Fund contributor and ships as a Blender extension-compatible add-on. Reviewing the developer's page before download is the safest way to confirm the latest terms.
Poly Engine - Retopology Best Friend places edge loops through a preview-based workflow: hold ALT and hover over an edge, and you'll see exactly where the loop is going before you click. Alongside loops, the add-on includes Quick Bands, which builds a whole strip of quads once you click your path. Both work through clicking, the same way you place individual verts by clicking and drag them to move them. That preview means you can judge each loop's position before committing it.
Poly Engine - Retopology Best Friend includes a smooth function bound to the R key: hold R and brush over your topology to smooth it out without pulling anything off the surface. It pairs with a Point Slide brush for nudging existing verts around, and an internal undo stack that stays separate from Blender's own history, so you can experiment freely without worrying about it. Ghost symmetry is also available for eyeballing the X-axis without committing to it.
