One of the more popular UV tools in the toolfarm library, RizomUV Virtual Spaces earns its place for a workflow built around speed, unwrapping, packing, and optimising in seconds. The 2025 release adds GPU Packing, a strategy selector, and the long-requested Scene Outliner.
RizomUV Virtual Spaces is Rizom Lab's UV mapping application for Cinema 4D artists, built around speed of workflow. It can unwrap, pack, and optimise in seconds, cutting UV work from hours down to minutes. Core capabilities include automated unwrapping with minimal manual adjustment, advanced packing algorithms, interactive distortion control, and intelligent seam placement. It's the CG-focused counterpart to RizomUV Real Space, which is built for CAD space.
The RizomUV 2025 release adds a rebuilt GPU Packing system (Windows CUDA only in this initial release), reported at typical 3–4x speed increases depending on the GPU and a 2–4% boost to average tile coverage. A new strategy selector offers Efficient, Padding Perfect, and Pixel Aligned modes across all devices, while a rebuilt Align UV to 3D orients islands to their original 3D orientation with selectable +U, -U, +V, -V targets and a customizable fallback axis.
Multi-tile and UDIM workflows gain Pack Island Groups to Tiles, with One-to-One and Mixed distribution, and the new Scene Outliner displays the object hierarchy for hiding, revealing, and isolating objects. Every UI preference and model property can also be saved as a default across sessions.
RizomUV Virtual Spaces is best for uV mapping for CG work, from indie stills to games and film, where fast unwrapping, packing, and optimising matter.
RizomUV Virtual Spaces is completely free to download and use.
RizomUV Virtual Spaces runs on macOS Big Sur 11 or above. The minimum setup calls for 8 GB of RAM, a graphics card with 2 GB of VRAM, and a 1920×1080 monitor, while the recommended macOS configuration steps up to 16 GB of RAM and an 8 GB VRAM graphics card at the same monitor resolution. Windows 10 and 11 (64-bit) and Linux are also supported. For the full, current requirements across each platform, check the developer's page before installing.
RizomUV Virtual Spaces introduced GPU Packing in its 2025 release, and this initial version is Windows CUDA only. On supported hardware, Rizom Lab reports typical speed increases of 3–4x depending on the GPU, along with a 2–4% boost to average tile coverage. The GPU packer was rebuilt from the ground up rather than ported from the CPU version, and it particularly excels with complex, concave, and interleaved island shapes, especially when working with fewer islands. The CPU packing path remains available across all devices and platforms.
RizomUV Virtual Spaces and its sibling RizomUV Real Space cannot both run as floating licenses on the same server. Virtual Spaces is the CG-focused edition, covering work from indie stills to games and film, while Real Space is built for CAD space. If you need both editions in the same environment, review the licensing terms on the developer's page to confirm how they can be deployed.
RizomUV Virtual Spaces is listed as free in this catalog. Licensing for UV tools like this can change over time and may vary by edition or license type, including floating licenses that come with their own deployment rules. For current pricing, license options, and any restrictions, check Rizom Lab's own page before committing, since that's the most reliable place to confirm what's included and how the application is licensed for your setup.
