V-Ray for Sketch-Up Two-Sided Material
The V-Ray for Sketch-Up Two-Sided Material, or VraySkp2SidedMtl as it appears in V-Ray for 
SketchUp, is simply a material that allows for the front faces of a material to have a separate 
material than the back faces. It can be very useful when creating very quick conceptual renders 
when trying to convey ideas with minimal modeling. This tool developed out of Sketch-Up users’ 
desire to create a V-Ray material that would act with different materials as the standard Sketch-
Up material does.
First we will need to add the Sketch-Up Two sided material. Open the material editor and right-
click on Scene materials and select VraySkp2SdMtl which is the last option.
The Sketch-Up Two-Sided material looks very similar to the V-Ray Two-Sided material. It has two 
slots; one for the front material, and another for the back material. As with the V-Ray Two-Sided 
material the materials cannot be created from within the Two-Sided material, but must be 
already created in order to be added to either the front or the back material. Although it Is 
possible to utilize much of the features of the standard V-Ray material within the Sketch-Up Two-
Sided material, it is not recommended to use any refraction layers within materials used for the 
Two-Sided material. Unlike the V-Ray Two-Sided Material, which needs a material for each side, 
the Sketch-Up Two-Sided Material will work just fine without a material defined for each side.
For whichever side does not have a material assigned, that side will not be rendered. This can be 
very useful for architectural visualization, and can be used to look inside rooms with the 
appearance of the wall still affecting the illumination of the enclosed environment.
