Material Id Enabled – Enables the use of Material ID.
Material ID – – The color used by the "Material ID" render element. You can also use a shader here.
Multimatte ID – The integer ID of the material to be used by the "Multimatte" render element.
Round Edges Enabled – Enables the round edges effect which uses bump mapping to smooth out the edges of the geometry during render time.
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.
Consider Same Object Only – When enabled, the rounded corners are produced only along edges that belong to the same object which has the attribute applied. When disabled, rounded corners are produced along edges formed when the object with the attribute intersects other objects in the scene.
Corners – Choose which edges are considered in the calculation. Possible options are:
Covex and Concave – Considers all edges. Convex Only – Only applies Round Edges effect to edges with convex angles. Concave Only – Only applies Round Edges effect to edges with concave angles.
Cutoff – A threshold below which reflections/refractions are not be traced. V-Ray tries to estimate the contribution of reflections/refractions to the image, and if it is below this threshold, these effects are not computed. Do not set this to 0.0 as it may cause excessively long render times in some cases.
Double-sided – When enabled, V-Ray also shades calculates separately the shading for the back -facing faces of surfaces with this material. Otherwise, only the front-facing surfaces are shadedWhen disabled, the back faces are shaded the same as the front faces.
Fix Dark Edges – When enabled, fixes dark edges that some times appear on objects with glossy materials.
