Vox Cleaner is an add-on that imports, optimizes, and exports MagicaVoxel files directly within Blender. It brings in object meshes, names, and transform data while preserving material properties such as color, roughness, metallic, emission, and transmission maps. The tool provides a single-click cleaning process to reduce geometry and optimize textures. It includes features for shared UV cleaning across multiple models, two-step cleaning for custom UVs, and support for Marching Cubes models. The add-on also streamlines exporting assets with their associated textures for use in external applications.
