RizomUV 2027.0 released: map-based UV control and batch processing

Rizom-Lab has released version 2027.0 of RizomUV, its UV unwrapping and packing software. The update, covered in a CG Channel article dated 8 October 2026, focuses on customizing workflows, processing complex assets more efficiently and integrating with production pipelines. The version numbering switched to an Autodesk-style scheme, so no major release named 2026 came after the 2025 release.

Texel density and UV editing tools

The map-based workflow, introduced for game and real-time visualization artists, makes it possible to control how a model’s texture budget is distributed across its surfaces. Density maps can be generated from ambient occlusion data, allowing texel density to be reduced on recessed surfaces. The maps affect both the unwrapping process and packing scale.

There are also changes to edge selection tools. Edge loops can now continue past UV seams, while parallel selections can extend across cuts. The Unfold and Optimize tools can align island edges with the U and V axes to automatically correct irregular boundaries.

Interface and performance updates

The workspace has been reorganized. Panels can be moved, docked or turned into standalone windows, and interface presets can be created for different display layouts. Frequently used tools can be grouped in custom toolbars, and a global search is available across tools and settings. The viewport has also been updated to make it easier to inspect selections and packing states, and to improve interface scaling.

For artists working with complex, assembled models, the Scene Outliner supports polygon groups and materials in imported OBJ and FBX files. Unwrapping processes islands in parallel across the scene, automatically selecting the fastest available solver core for each one. The Live Update setting also shows the effect of adding or removing an edge constraint in real time, without requiring manual application.

Automation, file formats and licenses

The new headless mode is designed for batch processing assets, creating automated build steps and running the software on render farms. Python is now the default scripting language: Python 3.13 is used on Linux and macOS, and Python 3.12 on Windows. The command log now records sessions as scripts; these recordings can be reused and developed into more extensive tools by technical artists.

RizomUV 2027.0 supports glTF 2.0 import and export. USD support has also been added to Mac; the feature has been available on Windows since RizomUV 2023.0. FBX files can store more data, including UV constraints and pins, and large FBX files can be opened selectively. The arrival of RizomUVLink on macOS and Linux also expands connectivity options. However, integration plugins for DCC applications are maintained by third-party developers, not Rizom-Lab, so current compatibility depends on the plugin.

The VS and RS editions are compatible with Windows 10+, macOS 11.0+ and the RHEL/Rocky/Alma 8/9 and Ubuntu 24.04 Linux distributions. Indie licenses offer perpetual or rent-to-own options, while Pro licenses are rental-only. For VS, a perpetual license costs €149.90, rent-to-own costs €14.90 per month, and Pro costs €34.90 per month. For RS, the corresponding prices are €299.90, €29.90 per month and €59.90 per month.

Impact on architecture and visualization workflows

RizomUV is described as a standalone UV tool used directly in game, VFX, motion graphics and product design work. As a result, its benefits for architectural visualization teams depend on how it connects to their modeling software and whether the plugin they use is up to date. In particular, parallel UV processing on complex scenes and headless mode for recurring assets offer options that can be added to a production pipeline.

Before upgrading, check operating system requirements, license type and the status of the DCC bridge in use. Not all third-party plugins may be up to date; support for new file formats also does not mean existing plugins are automatically compatible. Choosing a paid license and validating the production pipeline are important parts of the upgrade decision.
