Overview


The V-Ray 2-Sided Material is a utility material provided with the V-Ray renderer. The material shows light through the backside of the objects. Use this material to simulate thin translucent surfaces like paper, cloth curtains, tree leaves, etc. The translucency can be controlled by either a texture in the Translucency texture channel or by using the specified color.

Parameters



 

 

Front material – Defines the material to be used for front-side faces as defined by the object normals.

Back material – Defines the material V-Ray will use for back side faces as defined by their normals.

Translucency texture – Determines which side (Front or Back Material) relative to the camera is more visible in the rendering process. By default this value is 0.5, which means that both the side facing the camera, and the one facing away from it, will both be equally visible. When this parameter is closer to 0.0, more of the material facing the camera will be seen. When it is closer to 1.0, more of the back material is seen. 

Force single-sided sub-materials – When enabled (the default), the sub-materials will render as one-sided materials. Disabling this option is not recommended.

Multiply by front diffuse – When enabled, the translucency is multiplied by the diffuse of the front material.

Example: Translucency texture

 

The translucency can be controlled by either a texture in the Translucency texture channel or by using the color of the Translucency texture channel. The examples below show both controlling the translucency by color and also by use of textures (in this case V-Ray procedural textures).

 

 


Translucency texture 0.61, 0.61, 0.6

 


Translucency texture 0.25, 0.25, 0.25

 

 

 


Translucency texture 0.75, 0.75, 0.75

 


Translucency texture 0.9, 0.9, 0.9
