The VRayMtl2Sided material is a utility material provided with the V-Ray renderer. The material allows seeing the light on the backside of objects.

Use this material to simulate thin translucent surfaces like paper, cloth curtains, tree leaves etc.

Front – The material which is going to be used for front-side faces as defined by the object normals.

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

Use back material checkbox – When disabled, V-Ray will consider both sides assigned with the front material. When this is On, you can assign a different material from the front one.

Translucency – Determines which side (front or back) 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 be visible to the same degree. When this parameter is closer to 0.0, more of the material facing the camera is going be seen. When it is closer to 1.0, more of the back material is seen.

Multiply by front diffuse – When enabled, the translucency is multiplied by the diffuse of the front material. This option is not available when the renderer is set to GPU.

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