Parameters Values

This section provides you with the most frequent parameters you can get and their effects. They appear in the Rendering Properties dialog box when modifying an External Shader:

Category Type Name Comment
Color Specular Specular Strength Should be high to give a shiny effect to the material
  Specular Strength Should be high to give a shiny effect to the material (100 and above)
Paint mapping Texture Name Impact Paint 2D map with mipmaps
  Diffuse Gives a basic material color to the material, it must be impacted, except for specific effects
  Specular Gives more importance to environment reflections than direct lightning reflections when combined with Car Paint for example
Reflection mapping Texture name Reflection Cube map with mipmaps
  Impact Fresnel Fresnel
Reflection Impact Ambient Fresnel reflection is on the entire surface
BRDF effect Impact Diffuse Must be impacted
  Specular Should be impacted
Environment Parameters Environment Contrast Useful to boost reflections (modifies the contrast of the reflection map)
    Environment saturation Useful to set colors to Black and White (dark materials reflection is usually desaturated)
