base color – Specifies the diffuse color or map for the base layer.
base reflection – Specifies the reflectivity value or map for of the base layer. The reflection color itself is the same as the base color.
base glossiness – Specifies reflection glossiness value or map for the base layer.
base trace reflections – When disabled, the base layer only produces specular highlights, but no (glossy) reflections.
flake color – Specifies the color or map of the metal flakes.
flake glossiness – Specifies the glossiness value or map of the metal flakes. It is not recommended to set this above 0.9 as it may produce artifacts.
flake orientation – Specifies Controls the orientation value or map of the metal flakes . The orientation of the flakes is relative to the surface normal. When set to 0.0, all flakes are perfectly aligned with the surface. When set to 1.0, the flakes are rotated completely randomly with respect to the normal. Values above 0.5 are not recommended as they can produce artifacts.
flake density – Specifies the density (number of flakes) for a certain area. Lower values produce less flakes and higher values produce more flakes. Set this to 0.0 to produce a material without flakes. For more information, see The Flake Density Parameter example below.
coat color – Specifies the color or map of the coat layer.
coat strength – Specifies the strength value or map of the coat reflections when the surface is viewed directly from the front.
coat glossiness – Specifies the glossiness value or map of the coat reflections.
coat trace reflections – When disabled, the clear coat will only produce specular highlights, but no actual reflections.
environment priority – Specifies the environment priority for the environment override texture for this material. See the VRayMtl material for more information on this parameter.
This rollout provides additional control to contains the different texture maps for the various parameters of the material. Some maps are only exposed here and are not accessible from the parameters section.
base bump – Specifies the bump map for the base layer.
coat bump – Specifies the bump map for the coat layer.
environment override – Specifies a map for environment override. displacement –
Specifies a map for displacement.
