Rizom-Lab has released RizomUV 2025, its UV mapping software, with new GPU-based packing, workflow improvements, and stability updates. The release focuses on faster and more reliable packing, extended orientation options, and a new Scene Outliner for managing complex projects.
The main addition is GPU Packing, available on Windows with CUDA support. The system has been rebuilt to improve robustness and speed, typically offering three to four times faster results compared to the CPU version. It also provides more reliable packing of complex or stacked UV islands, completing tasks involving hundreds of thousands of islands in under a minute on recent GPU hardware. A new strategy selector introduces four packing modes: Efficient, Padding Perfect, Pixel Aligned, and Pixel Art.
The Align UV to 3D tool has been reworked to produce more accurate orientations, with options for different axes and fallback settings. For multi-tile and UDIM workflows, islands from groups can now be packed automatically into tiles using either dedicated or mixed distribution modes.
RizomUV 2025 also introduces the Scene Outliner, a feature requested by users, which displays scene hierarchies and allows hiding, revealing, or isolating objects. Users can now save all settings, including preferences and model properties, as defaults across sessions and reset them to factory values when needed.
Other updates include primitive selection conversion between vertices, edges, and polygons, a redesigned preferences window, new options for selecting borders and invalid topology, expanded trimsheet export formats, improved viewport tools, and refinements to menus and hotkey behavior. A significant internal code refactoring has also been carried out to prepare for future interface customization.
