There is one way to modify the UV size of textures in V-Ray in a relative way regardless of the UVs used. It serves as an indicator of the suggested UV size that needs to be manually set: This is why despite the peculiar way SketchUp's texture projection works V-Ray materials cannot store the data of UVs from SketchUp.įurthermore, you may notice some of the V-Ray library materials have a dimension at the end of their names. UVs are part of the object properties, not materials'.

The default texture size in SketchUp is 10' or ~0.25m Using any of those options allows adjusting the UV size based on the SketchUp texture size. I have exported the files with my design set as just a design, as Sketchup saving the item as a component, and as Sketchup saving the file as a Group item in all above formats.-I exported the Sketchup file as a 2D and dxf file. There, you can either select a custom Bitmap texture or use the generic 'Texture Helper'. Open the SketchUp file by clicking File > Open. This means UVs are only available when the material in SketchUp uses a texture (corresponding to the V-Ray Diffuse texture slot).įor nested and procedural textures or when a material lacks a Diffuse texture a couple of options are offered in the 'Binding' section of the V-Ray material settings.

V-Ray assumes object UVs in SketchUp from the texture projected on each object face in SketchUp. In the illustrations below I've only used a procedural V-Ray Checker texture in the Reflection slot to simplify the example: This is the size a V-Ray material's textures will assume if no object UVs are set. SketchUp's internal scale is always set to 1'.
