Monitor Shader

The RTT Monitor shader simulates the appearance of a flat screen display where saturation decreases at grazing angles of view. Therefore, the shown color texture blends into the diffuse color of the material. In addition, a reflection from the surrounding (from a cube map) is added, increasing in strength towards more acute angles of view.


Note: This plug-in is located in: Built Ins -> Shader -> RTTAdvancedMaterials

Monitor Shader Properties


  • Saturation/Reflection/Color Gradient: Defines to which amount the material’s diffuse color is mixed into the resulting color at grazing angles.

  • 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.

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

  • Technique: Shows a list of available techniques.

    • Saturation_and_Reflection_Gradient: Is a technique to influence saturation and reflection appearance alike.

    • Reflection_Gradient: Is a technique to influence only the reflection appearance.

Monitor 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. For this shader, a background image should be selected as the basic texture to achieve a highly realistic monitor effect. 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.
