No. Voxel Master is a native Geometry Nodes group asset. You just append or link it into your file from the asset library like any other node group. No Python add-ons, no extra installs.

It is built for modern Blender versions that support Geometry Nodes assets. Blender 4.x is recommended. If you are on an older version, feel free to ask before purchasing.

The debug panel exposes three outputs: the original input mesh, the thin areas mask, and the final calculated voxel size. These are useful for inspecting what the node is doing internally and for piping values into other parts of your geometry nodes setup.
