The Blender edition of UV-Packer consists of two components: the UV-Packer engine itself, and a Blender integration plugin. The product website shows the plugin achieving 48% UV packing efficiency for an 80,000-polygon building model, as opposed to 28% for Blender’s native tools.įree for commercial use, but the SDK remains a paid product

UV-Packer is multi-threaded and, according to 3d-io, is capable of “crunching thousands of UV islands and millions of polygons in minimum time”. It is resolution-independent – so packing times remain constant, regardless of the resolution of the textures – and supports tiled UV layouts, used in applications like ZBrush. The software automatically arranges the UV islands of a previously UV-unwrapped 3D model to minimise wasted space, reducing total file sizes for sets of texture maps. UV-Packer began life as a commercial 3ds Max plugin, with 3d-io making the 3ds Max edition available free on the release of version 3 last year. Plugin developer 3d-io has released UV-Packer for Blender, a new edition of its free UV packing plugin for the open-source 3D software.ĭesigned for “3D artists, game studios, arch viz, photogrammetry … and 3D product designers”, the plugin optimises the packing of UV islands for both organic and hard surface models to minimise wasted UV space.Ī high-performance automated UV packing plugin Scroll down for details of the new macOS edition.
