This page provides some details on the settings available for the Translucent Two-Sided Material in V-Ray.

Page Contents ×


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 material – 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.

Translucency tex – 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 the more of the material facing the camera is going to be seen. When it is closer to 1.0, the more of the back material is seen.

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

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.



  • This material will give best results when assigned to singleside objects (non-shelled) objects like planes, extruded splines etc. Otherwise it can lead to extremely longer render times.
