Spec score 7.6 #14 of 26 in Voxel Editors

What it is

Sproxel is a free, open-source 3D interface for making and editing voxel models, using cube-based forms as an extension of 2D pixel art. It can generate sprites for custom displays or game engines. Version 0.4 supports importing BMP, GIF, JPEG, PNG and TIFF images into voxel grids, and exporting OBJ meshes as quads or triangles without internal polygons. Version 0.5 added grid resizing, draggable tools with previews, voxel outlines, camera snapping and a two-click Line tool. Version 0.6 added multi-sprite projects, a Python plug-in system, Paint3D (.3MP) import and export, slicing, and indexed-color grids with a 256-color palette. The maker describes it as developed on Windows and Linux using the QT windowing framework; the listed platforms are Windows, macOS and Linux. The download is described as a package that can be copied to a directory and run without installation. The package has no help file, and the maker points users to a manual. The version 0.6 release post said its download was win32 only at that time.
