Front – The material used for front-side faces as defined by the object normals. Back material –The material used for back side faces as defined by their normals. Use back material checkbox – When disabled, V-Ray considers both sides assigned with the front material. When enabled, 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 render as one-sided materials. Disabling this option is not recommended. |
