Beta Quad earns its place with a fully original retopology algorithm the developer built over several months without commercial or open-source libraries, aimed specifically at selected n-gon faces. A successor, Delta Quad, is also available from the developer.
Beta Quad is a retopology tool for Blender that works on selected faces. You can retopologize a single n-gon face or a part of a mesh, or select all faces at once. Its focus is quad retopology of a selected n-gon face, converting a large n-gon into small quads.
The tool uses an originally designed algorithm built without commercial or open-source retopology libraries. It respects the border direction of an n-gon and creates quads that follow the shape of the original face. A quad size parameter sets how many quads appear in the result, and options include keeping edge flow along the boundary and an inset boundary that adds thin supporting edges to keep the border sharp without mean-crease in subdivision.
Beta Quad keeps the original face's edges and remeshes a face rather than replacing it, so it does not suit sculpted meshes or high-poly triangle meshes, and it skips faces smaller than the quad size. Written in Python, it runs on Windows, Mac and Linux. One common use is to quickly remesh a mesh, then deform it with Blender's proportional editing to bend, twist or pull the surface.
Beta Quad is best for retopologizing a selected n-gon face or part of a mesh into small quads.
Beta Quad is completely free to download and use.
Beta Quad was updated in version 2.3.0 to work with Blender 4.0.0, fixing a bug caused by a Blender API change, and version 2.4.0 fixed a further compatibility problem. For the specific Blender versions supported by the current release, check the developer's page. The tool is written in Python, which the developer chose so it can keep working across platform and OS upgrades without recompiling, and so updates can be rolled out and tested without a compile step.
Beta Quad is designed for selected n-gon faces and is not suited to sculpted meshes or high-poly triangle meshes. It keeps the original face's edges and remeshes a face rather than replacing it, so it is not intended for remeshing a whole mesh full of sharp n-gons and bad topology. It also skips any face smaller than the quad size, which means a high density of quads is needed. The developer notes the tool is still under development and these limitations may change.
Beta Quad is coded in Python and runs on Windows, Mac and Linux. The developer chose Python specifically to keep the add-on cross platform, avoiding OS-specific compiled binaries so it does not suffer from platform upgrades. Because Python runs slower, retopology of complex meshes is slower than some other tools, but the tool focuses on selected faces, so the developer notes this is not a problem for its intended use.
Beta Quad includes a quad size parameter that determines the number of quads in the result. Because of this, the developer advises against using it on very large or very small scaled meshes, since it may create millions of quads for a single face or lack the space to work. Faces smaller than the quad size are skipped entirely, so the parameter is central to controlling the density of the retopologized output.
Beta Quad is listed as free in this catalog. Licensing terms can change, so check the developer's page on Superhive for current details before relying on it. Note that the developer describes Beta Quad as experimental and not yet a perfect product, able to handle only simple meshes, and points buyers to its successor, Delta Quad. The developer's page is also the place to support continued development of the add-on.
