VRayCarpaintUberMtl

This page provides an overview of the VRayCarpaintUberMtl and its parameters.

Overview

VRayCarpaintUberMtl simulates metallic car paint. It is a complex material with two layers: a base layer and a clear coat layer. The material allows the adjustment of each of these layers separately.

VRayCarpaintUberMtl Parameters

Specifies the properties of the base layer for the car paint.

• SolidColor – Specifies the diffuse color of the base layer.
• FlipFlop – Enables a flip-flop or chameleon effect for the base layer.
• PearlescentColor – Specifies the color at the Fresnel reflections. Note that this color also depends on the MetallicAmount parameter.
• PearlescentBIas – Controls the Fresnel amount of the PearlescentColor.
• MetallicAmount – Specifies the metallicness of the base layer.
• MetallicGossiness – Controls the sharpness of reflections. A value of 1.0 means perfect mirror-like reflection; lower values produce blurry, or glossy, reflections.

SolidColor=0.05,0.05,0.6; MetallicGlossines=1; CoatStrength=0

SolidColor=0.05,0.05,0.6; MetallicAmount=1; CoatStrength=0

SolidColor=0.05,0.05,0.6; FlipFlop=On; PearlescentColor=0.9,0.7,0.1; MetallicGlossines=1; CoatStrength=0

Specifies the properties of the top coat layer of the car paint with additional reflection and bump properties.

• CoatStrength – Specifies the strength of the Clear Coat layer.
• CoatGlossiness – Controls the sharpness of reflections of the Clear Coat layer. A value of 1.0 means perfect mirror-like reflection; lower values produce blurry, or glossy, reflections.
• UseBumpTex – Enables the use of Texture for Bump of the Clear Coat layer.
• BumpTex – Specifies the Bump Texture for Clear Coat layer when UseBumpTex is enabled.
• BumpTexAmount – Specifies the bump amount of the Clear Coat layer.
• BumpTex_Channel – Specifies the UV channel index for the BumpTex of the Clear Coat layer.
• BumpTex_OffsetU – Specifies the horizontal offset of the BumpTex of the Clear Coat layer.
• BumpTex_OffsetV – Specifies the vertical offset of the BumpTex of the Clear Coat layer.
• BumpTex_TileU – Specifies the horizontal repetition of the BumpTex of the Clear Coat layer.
• BumpTex_TileV – Specifies the vertical repetition of the BumpTex of the Clear Coat layer.
• BumpTex_Triplanar – Enables triplanar mapping for the BumpTex of the Clear Coat layer.
• BumpTex_TriplanarBlend – Specifies the blend amount between the different Texture projections. Lower values produce sharper transitions between projections.
• BumpTex_TriplanarScale – Adjusts the scale of the BumpTex of the Clear Coat layer when BumpTex_Triplanar is enabled.
