Rizom-Lab RizomUV Real & Virtual Spaces 2025.0.101
Introduction
Released on 15 September 2025, build 2025.0.101 patches the landmark 2025.0 branch that debuted GPU packing. The installer is only 220 MB but swaps in faster island orientation logic, tighter UDIM auto-fit, and a hot-fix for zero-area degenerates that could corrupt texel density. Indie and Pro users on current subs can auto-update without touching their licence seats.
Headline Features
GPU packing now runs on Windows CUDA cards, showing 3-4× speed-ups even on eight-year-old hardware. Four selectable strategies—Max Coverage, Fastest, Minimal Artefact, Pixel-Art—let you bias for hero assets or background props. The new Scene Outliner lists meshes, UDIM tiles and groups in a collapsible tree, so hiding a sofa or isolating a car seat is one click. A rebuilt “Orient by 3D” algorithm keeps wood grain or fabric weave pointing the right way after unwrap.
Why The Update Matters
Studios tackling large environments often leave UV work till the end; the faster packer turns overnight batches into coffee-break tasks. Game artists gain tile-based packing groups that auto-drop into the correct UDIM, saving manual shuffle time. Product designers using Real Space can now lock metric scale while still enjoying the GPU boost—vital for laser-texturing templates that must match millimetre specs.
Practical Uses
Arch-viz teams unwrap entire furniture sets in minutes, pack to UDIM 1001-1012 and send to Twinmotion without manual tile assignment. Shoe manufacturers use Real Space mode to flatten a 290 mm sole pattern at true scale, then export the UV layout as a DXF cutting guide. Indie gamedevs on tight steam-deadlines batch-process 500 prop variants overnight, choosing the Pixel-Art strategy to keep hard-edge padding tight.
Ease of Learning
Existing users will find zero UI shuffle; new icons live in the same Pack panel. A five-minute “GPU First Steps” clip shows how to pick strategy and monitor VRAM. Default hot-keys remain intact, so studio training material still applies. Preferences can now be exported as a single JSON file, making it simple to sync across a render-farm.
Expert Review
Build 2025.0.101 feels like a polish pass rather than a feature dump, but that is exactly what a production tool needs. GPU packing delivers measurable 4× gains on RTX 4070, while the new outliner finally treats heavy scenes like a DCC app rather than a single-model unwrapper. The degenerate-island hot-fix alone saves hours of clean-up on photogrammetry scans. At the current indie price, the value proposition is hard to beat.
Quick Insights
RizomUV 2025.0.101 cements Rizom-Lab’s lead in standalone unwrapping: GPU speed, CAD precision, and game-art workflows now live under one roof. Update, hit Pack, and spend the reclaimed hours on creativity, not UV babysitting.
Frequently Asked Questions
Q1. Is GPU packing available on macOS or Linux?
A1. Currently Windows-only; CUDA core required.
Q2. Will old scripts break after updating?
A2. Lua API is backward-compatible; new ZomEval command simply exposes extra GPU flags.
Q3. Can I still use CPU packing if my card is old?
A3. Yes, CPU packing remains and now also supports the four new strategies.
Q4. Does the Real Space licence cover Virtual Spaces?
A4. Yes, Real Space users can launch in VS mode with the -vs flag at startup.
