How to generate colorful glass with refraction layer in vray sketchup
This is a useful presentation from MasterTuts that shows the users some tricks to generate a material in v-ray for sketchup by applying refraction layer.
Refraction indicates the modification of direction of a ray of light in moving at an angle from one medium to another. In V-Ray the refraction layer is applied to generate glass or translucent materials.
Generally the refraction layer is located beneath the Diffuse layer and the diffuse layer obstructs the effect of the Refraction layer. To view the refraction effect, Just apply transparency in the diffuse layer.
