Lacquered Surfaces Shader

The RTT Lacquered Surface shader simulates smooth lacquered surfaces lit by a highlight. On the clear coat layer, the surrounding is reflected (from a cube map). The reflection blurriness can be controlled to create the appearance of a rougher surface.

Lacquered Surfaces Shader Properties

  • Environment Reflectivity: Manipulates the influence of the reflection color from the environment map on the resulting color.

  • Reflection Multiplier/Exposure: Affects the exposure of the environment map. This is especially helpful when working with HDR images.

  • Gamma of EnvMaps: Controls the gamma correction of the environment map. This is once again particularly helpful when working with HDR images.

  • Blur Reflection: States how much the environment reflection is blurred to create the impression of a rougher surface.

  • Fresnel Minimum, Fresnel Scale and Fresnel Exponent: Affects the Fresnel effect upon the reflection.

  • Environment Map: Is a cube map that describes the environmental surrounding used to calculate reflections.

  • Technique: Shows a list of available techniques.

    • PixelShading: Is a technique to be used for finer details on the surface.

    • VertexShading: Is a technique to be used for objects in the distance or for highly tessellated objects.

Lacquered Surfaces Shader Best Practices

Apart from the parameters in the plug-in container, it is necessary to assign a material and a texture as a color/basic texture. Do not forget to adjust material parameters in addition, such as ambient, diffuse, specular color and shininess, to achieve the required look for your surface.
