The UVPackmaster team is glad to announce a new update for UVPackmaster 3 for Blender! Of course you get the update for free, if you already purchased UVPackmaster 3 - you can download the latest version of the packer from the marketplace, where you bought it:


Release 3.1.0 General improvements

  • Mac support (Intel and Apple M1). For more info regarding Mac-specific requirements visit the documentation.
  • Drastically significant performance optimizations for UV maps containing a huge number of UV faces (a few millions and more). Our benchmarks show that the new engine release can now pack a UV map containing 15 million faces in about 160 seconds. Generally you should notice an algorithm speed up starting from UV maps containing a few thousands of faces. All users who are going to deal with heavy UV maps (e.g. for photogrammetry applications) should read this article in the documentation – it provides a bunch of additional useful tips.
  • New mode for aligning islands: Topology. This most-advanced mode takes into account not only vertex positions of two UV islands, but also how the vertices are connected (island topology). For more information on how the aligning tools were refactored in the new release read this article in the documentation.

  • Support for Blender downloaded from the MS Store (on Windows).
  • New auxiliary operation for island grouping: Apply automatic grouping to a grouping scheme. Read this article to learn more about this functionality.

Bug fixing and minor improvements

  • Fix for crashes when pixel margin parameters were set to larger values.
    Increasing the Texture Size max value to 32K and the Pixel Margin and Pixel Padding max values to 256.
  • Fix for a packer hang when using an automatic grouping method together with the Pack To Others mode.
  • Fix for occasional packer crashes when using the Normalize Islands option together with GPU packing.
  • Other minor bug fixes.
