Parameters

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, are 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, multiplies the back side color by the cached diffuse color of the front BRDF.

Force Single-sided Sub-materials – When enabled (the default), the sub-materials render as one-sided materials. Turning this option off is not recommended.

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