Reflectancy

SHADER TYPE: Plastic

Plastic is a reflectivity type that creates a shiny, plastic-type reflection. This reflectivity type is especially suitable for shiny, polished materials, such as plastic and lacquered surfaces. As a reflectivity type, Plastic is similar to Phong.

Parameter: Explanation: Default value: Possible values and comments:
Ambient Factor Reflectivity factor of ambient light 1
Diffuse Factor Reflectivity factor of diffuse light 0.75
Specular Factor Specular factor 0.5
Roughness Reflection sharpness factor 0.1 The larger the factor, the sharper the reflection. High values like 10 make the surface more mirror-like.
Specular Colour Colour of the reflection (255,255,255) All RGB values
