In RizomUV RS, the plane will retain its dimensions, 4x4m^2 in the existing UV space. As an example, should you unwrap a 4x4m^2 plane in RizomUV VS, the plane will be rescaled to 1x1m^2 in the existing UV space. Unlike in RizomUV VS, RizomUV RS will rescale the UVs to fit into a unified square, as well as retain the real dimensions and scale of your object. Pick RIzomUV RS if the UV Maps you need to generate will be used as unwraps and guides for Real-World Objects. RizomUV will propose you everything you need in that domain too. Some projects need to get the lower stretch possible under specific constraints such as vertex pinning or edge orientation. Giving low-stretch UVs is often not enough. RizomUV proposes many local edition tools, like stretch reduction brushes with masks, deformation box, proportional transformation, real-time deformation, several dozen of alignment tools, and several mesh segmentation tools. RizomUV Real Space offers BigTiff export format, that can handle huge images, breaking the 4 gig boundary, and so creating UV stamps at extremely high resolution, such as the ones necessary for laser texturing processes. Most classic file formats use 32bit offsets and, as such, are limited to 4 gigabytes (65,535×65,535 pixels), which can be limiting. With a curved surface, you’ll get the lowest stretching possible. If your 3D surface is developable, you’ll get zero stretching at all in your UVs. RizomUV uses advanced algorithms to create almost stretch-free UV Maps using energy minimization methods, like the ones used in finite element software.
In presence of a difference in lengths between the two spaces for the same element, you’ll notice it immediately.
RizomUV RS considers neutral stretch when the 3D lengths equal the UV ones. That’s why we’ve taken pains to make sure our stretch heat map displays accordingly to your needs. It can flatten +1M poly models with real-world measurements into perfectly flat, non-overlapping maps fastly. It doesn’t matter if you have a complex mesh, or a mesh full of non-quads.
