Info

Image below shows the influence of Refraction Glossiness material to objects behind it. Objects further away become very blurry. Shadows of refractive materials There is an Affect Shadow option to the right hand bottom corner of the Refraction dialog box, default is unchecked. When checked, the color of the transparent object will affect its shadow and it's not black anymore. The shadow also becomes more depth as well. It is recommended to always have Affect Shadows checked, as it produces a more realistic effect Images below show the difference with and without the Affect Shadows checked. 36 V-Ray for Rhino
Double-sided material Under Options of each material, you will find this Double-sided selection. Default setting is checked. This option is particularly important for transparent material. When this option is unchecked, light enter to the inside surfaces will not be rendered and show up black. The reason to have this option is that sometimes you may want to uncheck this option when render object with translucent material (See next page) in order to get the right texture. Unless you want to create some special effects, please have this option checked The double sided option will not have any affect on the shadows of the object Translucent material We've talked about changing the Diffuse color to get the degree of transparency we want to create before. White means 100% transparent, black means 100% opaque. You can create translucent materials with colors anywhere between white and black. But now we want to introduce a different translucent material. It is related to special light absorption materials. Open file: Translucency.3dm and render it, you will get image like below on the left. You will see that colors where partitions meet the outside box and at the base of the box are darker. This is because the thickness of the object changes and the light travel distance changes also. So the degree of light absorption varies. To create this kind of material, you have to check the Translucency option under the Refraction. Image on the right is the rendered result for Layer 02. V-Ray for Rhino 37
