RizomUV Real Space stands out in the toolfarm library because it preserves true-to-life dimensions rather than normalizing the UVs like its Virtual Spaces sibling, a distinction that matters when the flattening becomes a manufacturing blueprint. It sits at rank 33 on toolfarm.
RizomUV Real Space is a precise mesh flattening tool from Rizom Lab, crafted for professionals who create real-world products. It generates UV maps that maintain the actual real-world dimensions of the 3D model, so the scale and proportions of the layout match the original. That suits workflows where precise measurements matter, such as laser surface texturing, inflatable structure design, and CAD-like tasks. It includes all the features of RizomUV Virtual Spaces, plus algorithms and settings tailored for the physical world.
Flattening handles complex meshes and non-quads, working through over a million polygons in seconds to produce flat, non-overlapping maps that carry real-world measurements. Models made of multiple islands are packed into the allocated UV space, which can use open or closed boundaries to simulate physical shapes like sheets or ribbons. Island position and orientation can be locked, with customizable padding and margin.
Stretch analysis uses algorithms similar to finite element methods, producing no stretch on developable surfaces and the lowest possible on curved ones, while a heat map and stretch bar make any disparity measurable. Constraints add horizontal and vertical alignment, alignment with breaks, and hard and soft vertex pinning. Meshes import in OBJ, FBX, and USD.
RizomUV Real Space is best for professionals whose flattening will serve as a blueprint for manufacturing a physical object, including laser surface texturing, inflatable structure design, and CAD-like tasks.
RizomUV Real Space is completely free to download and use.
RizomUV Real Space runs on Windows 10 and 11 (64-bit), macOS Big Sur 11 or above, and Linux. On Windows it needs a DirectX 11 graphics card, and both Windows and macOS call for a 1920x1080 monitor. The Windows minimum is 4 GB RAM and 2 GB VRAM, with 16 GB RAM and 4 GB VRAM recommended, while the macOS minimum is 8 GB RAM and 2 GB VRAM. On Linux, run chmod +x on the launcher before starting it, otherwise it will not execute.
RizomUV Real Space imports polygon meshes in OBJ, FBX, and USD file formats, and it also supports exporting your work. You can bring a model into the application in any of those three formats, then flatten it into non-overlapping UV maps that carry the model's real-world dimensions. This makes it straightforward to move a mesh in from another tool and prepare it for a precise flattening workflow. For the full export details, check the developer's page.
RizomUV Real Space preserves the actual real-world dimensions of your 3D model, keeping the scale and proportions of the UV layout aligned with the original, which is the right choice when your flattening will act as a blueprint for manufacturing a physical object. Its sibling, RizomUV Virtual Spaces, normalizes the UVs into a standardized space instead, which suits visuals, game assets, and other digital content. Note that a floating license of both Virtual Spaces and Real Space is not allowed on the same server.
RizomUV Real Space is listed as free in this catalog, so no price is shown here. For current licensing terms, including the floating license rule that Virtual Spaces and Real Space cannot both run on the same server, refer to the developer's page. That is the best place to confirm any conditions tied to your specific use, and to check the latest details before you rely on the tool for a project.
