AutoRemesher for Blender is an extension that brings automatic quad remeshing into Blender. Remeshing takes a high-polygon 3D model, the kind produced by sculpting or 3D scanning, and rebuilds it with a cleaner, more even grid of four-sided faces called quads, which is much easier to animate, texture, and edit than the original dense mesh. This project is a fork that ports an existing desktop tool called AutoRemesher into a Blender extension, while all credit for the underlying remeshing engine goes to the original author. Inside Blender, the tool adds a panel to the 3D viewport where you select a mesh, adjust settings like target quad count and how much detail to preserve on sharp edges, and press a button to remesh. A few features are specific to this Blender version: the remeshing work happens in a separate background process, so if it crashes it will not take down Blender itself, and you can press Escape to cancel a run in progress. It also has settings to keep thin parts like claws, horns, or spikes from being flattened away, to give small disconnected pieces such as teeth extra detail instead of turning them into blobs, and an option to fuse overlapping shapes into one solid surface before remeshing. If part of a model fails to convert into quads, it keeps its original triangles instead of dropping that geometry. Installing requires Blender version 5.1 or newer, or an older Blender 4.2 through 5.0 using a separate download build. You install the extension zip file from Blender's own extension installer, then use it directly in the viewport. The tool can also be built from source using a Python and C++ toolchain. So far it has mainly been tested on Apple Silicon Macs, with builds for Windows and Linux available but less tested. The core remeshing code is under the MIT license, while the Blender extension wrapper itself is under GPL 3.0, a requirement for extensions distributed through Blender's official extension platform.
