Polygen earns its place in the superhive library for handling retopology and remeshing through a live point-based simulation. It's a Dev Fund Contributor released under GPL, and the developer invites bug reports and questions by email.
Polygen is a Blender add-on built on a point-based simulation that dynamically reshapes mesh topology. It scatters, evolves, and connects points across surfaces to deliver customizable quads and triangles in real time. The developer positions it for refining high-poly sculpts, optimizing game assets, and creating smooth, organic forms.
Adaptive retopology lets you paint points or draw guide paths, snapping agents to your mesh with raycast accuracy. Smart meshing then generates quads and triangles from agent positions, with optional subdivision and shrinkwrap modifiers. Quad size, repulsion, and attraction are tuned from a sidebar, and an auto-generation option keeps updates hands-free. A minimalist UI adds a progress bar and a toggleable help overlay, while hotkeys handle adding points, drawing guides, removing points, undoing, and generating the mesh.
Polygen is released under the GPL license and lists Blender 4.4 support. Version 0.2 fixed a RuntimeError tied to the add-on's invoke callback.
Polygen is best for refining high-poly sculpts, optimizing game assets, and creating smooth, organic forms in Blender.
Polygen is completely free to download and use.
Polygen lists Blender 4.4 as its supported version, so that release is the safe target for running the add-on. It operates as a point-based simulation inside Blender, scattering and connecting points across your mesh to build new topology. If you work on an older or newer Blender build, check the developer's page for current compatibility details before installing, since the listed version is the reference point here. Confirming your Blender version first helps avoid surprises when launching the simulation.
Polygen is released under the GPL license. That means the add-on's code is covered by GPL terms, which set out how you can use, modify, and share it. If you plan to redistribute or build on the add-on, review the full GPL terms and the developer's page for any additional conditions. For licensing questions specific to your situation, the developer AlbertoFX can be reached directly through the listed contact.
Polygen is listed as free in this catalog. Pricing and licensing can change over time, so for the current terms and any download details, check the developer's page directly. The add-on is distributed under the GPL license and was published by AlbertoFX. If you have questions about availability or how to get the latest build, the developer's page and listed contact are the best places to confirm before you download.
Polygen is driven largely by hotkeys during the simulation. Left-click adds points in Points mode or draws guides in Guides mode, while right-click removes the point under the cursor. Enter generates the mesh manually, Z undoes the last action, and ESC exits the simulation. Holding Ctrl shows the options bar, and H toggles the help overlay. Dynamics such as quad size, repulsion, and attraction are adjusted from the sidebar, with an auto-generation option for hands-free updates.
