Setting them there will allow for more visual feedback of the mapping, since Vray repeats will not be visual in viewport. My advice would be to set UV repeats via Rhino's mapping tools as opposed the the V-Ray options. Most people don't leave the mapping widget the same size, so the repeats will be happen with a smaller texture space, and then look weird and crazy like you posted. may not be appropriate for all ages, or may not be appropriate for viewing at work.

However once you start creating a actual projection type (planar, box, spherical.) then the repeat will be generated from the start of the mapping widget to the end of the mapping widget. Steam Workshop::Rhino-Scarab Sect V2 l Skin+Helmet. In some cases adjusting the UV repeat values may be a good way to set your mapping. By default, adding a texture will use the default UV space of the surface which is generated by its base structure. UV repeat takes a given texture space (from 0 to 1) and telling the image to repeat multiple times within that span. You can use the uv repeat, its just that going back and forth between adjust mappings and UV values can be confusing. Re: Mapping problem between viewport and render

I think this is the same issue as was discussed but never resolved here. Note that only the fence is being affected, everything else is ok. In this one no matter what we did the texture is lost in the render. In many of the files it's as simple as a texture being stretched in the render, but looking ok in the viewport and again nothing will change it. Here is one of the more obvious examples. Every time the changes are shown perfectly in the render viewport but not in the actual render.

I've also tried re-drawing the objects in question, deleting and replacing the material, deleting and replacing with another material. I've have had a look at the widgets, and have tried altering every option in the mapping dialog box. Unlike RhinoScript, Grasshopper requires no knowledge of programming or scripting, but still allows designers to build form generators from the simple to the awe-inspiring. I've made sure that the objects don't have any coplanar surfaces, and only have one channel. For designers who are exploring new shapes using generative algorithms, Grasshopper® is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. And the problem is happening on all different types of projection modes. Also, this is only happening on a few objects in their scene not all. Also no amount of changing the mapping properties can change the mapping in the render. They are applying mapping to each object through the objects properties and it's looking great in the viewport, however it then renders out differently to what they are seeing. At least 10 - 15 of them (out of 80) are having a weird issue with the mapping. My students are having some issues that I can't figure out.
