Radius - specify a radius (in world units) for the round edges effect. Since the actual geometry is not being changed and only the normals of the faces are affected large values here may produce undesirable effects.

Round Edges
Single
Image AddedThis node is the default material node. It requires that a BRDF node is connected to its input.
Double Sided - if this is checked, V-Ray will flip the normal for back-facing surfaces with this material. Otherwise, the lighting on the "outer" side of the material will be computed always. You can use this to achieve a fake translucent effect for thin objects like paper.
Allow Negative Colors - if this is checked the user can use negative values in the color swatches of the connected BRDF.

Two Sided
Image AddedThis is a utility node 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 - this is the material which is going to be used for front-side faces as defined by the object normals.
Back - this is the material V-Ray will use for back side faces as defined by their normals.
Translucency - this 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.
Force single-sided sub-materials - when is is on (the default), the sub-materials will render as one-sided materials. Turning this option off is not recommended.

VRmat
Image AddedThis node allows you to load a material from a .vrmat, .vismat or a .vrscene file
File - a slot for the .vrmat or .vismat file
Name - a slot for the .vrscene file

Wrapper
Image AddedThis node can be used to specify additional surface properties per material.
Base Material - this is the actual surface material.
Alpha contribution Tex - determines the appearance of the object in the alpha channel of the rendered image. A value of 1.0 means the alpha channel will be derived from the transparency of the base material. A value of 0.0 means the object will not appear in the alpha channel at all and will show the alpha of the objects behind it. A value of -1.0 means that the transparency of the base material will cut out from the alpha of the objects behind. Matte objects are typically given an alpha contribution of -1.0. Note that this option is independent of the Matte surface option (i.e. a surface can have an alpha contribution of -1.0 without being a matte surface)
