Łukasz Czyż releases UVPackmaster 3 for Blender

Friday, January 14th, 2022 | Posted by Jim Thacker

Developer Łukasz Czyż has released UVPackmaster 3 for Blender, the latest version of the GPU-accelerated UV packing plugin for the open-source 3D software.

The update moves the plugin to a new Python-scriptable architecture, making it possible for users to customise its functionality; and adds new options for stacking and aligning UV islands.

A fast, efficient GPU-accelerated UV packing tool
First released in 2018, UVPackmaster is a fast, efficient UV packing plugin capable of running on CUDA-enabled Nvidia GPUs as well as a workstation’s CPU.

It enables users to adjust the results on a per-UV-island or per-group basis, and supports tiled UV layouts, including UDIMs, and non-square layouts. You can see a summary of its features here.

New in version 3: Python scriptability and new UV stacking options
The main change in UVPackmaster 3 is that its functionality is now scriptable: the main packing algorithm is provided as human-readable Python code, as well as compiled engine code.

As well as making it possible for users to customise the plugin’s functionality to fit their own workflows, the online FAQs say that the new architecture will speed up development of new features.

The release also introduces options for aligning and stacking identical UV islands to reduce use of UV space.

Other features shown in the overview video embedded at the top of the story include UDIM packing using named UV groups, and the options to lock groups of UV islands to maintain relative positions.

In addition, the plugin – previously available in Standard and Pro editions – is now available only as the full-featured Pro edition.

Pricing and availability
UVPackmaster 3 Pro is available for Blender 2.83+, running on Windows 10+. Linux and macOS support will follow “soon”. A new single-user licence costs $39; multi-user Studio licences start at $119.

Łukasz Czyż tells us that the 3ds Max edition of the plugin is no longer for sale until it is ported to the version 3 codebase, but that existing users will continue to receive product support.
