9 MATERIALS REFERENCEOn metallic surfaces the roughness can vary against the surface direction. Especiallywhen the surface is finished. Due to this the roughness can be separatelyset in U and V direction.» Metal Type: The Metal Type attributes allows to choose between a wide rangeof metal material presets.» Reflectivity: Sets the BrushedMetalMaterial’s reflective intensity.» Clearcoat Settings Sets the clearcoat color. The clearcoat is a transparent,strongly reflective paint layer on the base metal layer.» Clearcoat Type: The Fresnel Term describes the intensity of a reflection basedon the viewing angle. Its intensity at normal incidence is set by the material’sreflectivity.• Off: Turns off the clearcoat.• Fast: Uses a fast but less accurate approximation to the Fresnel Term.• Accurate: Uses a physically accurate evaluation of the Fresnel Term.» Clearcoat color: Sets the clearcoat color.» Reflectivity: Sets the clearcoat reflective intensity.» Brush Orientation234» Brush Mapping: Allows to choose between a range of possible brush orientations,e.g. metal brushed in one direction or metal with radial brushes. For example,Brush Mapping ‘Radial XY’ simulates radial brushes within the xy-plane. The projectionplanes are defined relative to the object coordinate system of the objectthe material is assigned to.• Size U: Defines the brush’s size on the U-axis.• Size V: Defines the brush’s size on the V-axis.» The properties of the chosen Brush Mapping can be further modified.• Planar Mapping (Brush Mappings ‘Planar XY’, ‘Planar XZ’, ‘Planar YZ’)
