7 MATERIALS REFERENCE• Solid: Renders the Shadow white by default.» Sort key: Sets the render priority of the Shadow. Only supported in OpenGLmode.Reflection Settings:» Reflection Mode: Offers three different reflection modes:• Diffuse only: Shows only the diffuse reflections.• Glossy only: Shows only the glossy reflections.• Diffuse + Glossy: Shows the diffuse and glossy reflections.» Diffuse Color: Sets the shader’s diffuse reflection color. This is the color theshader takes on, when the light reflection of the surface is spread to manydirections.» Glossy Color: Sets the shader’s colour for glossy reflections.Glossy reflections result from irregularities of a surface at a microscopic level.Reflection behavior is described by the law of reflection which states that thedirection of incoming light (incident ray) and the direction of outgoing light reflected(reflected ray) form the same angle with respect to the surface normal,thus the angle of incidence equals the angle of reflection. Since a surface is usuallynot perfectly smooth, the orientation of the normals varies, thus creatinga glossy reflection.» Reflectivity: Sets the material’s reflectivity intensity.» Roughness: The roughness parameter defines the amount of diffuse reflectionand its complement specular reflection. The higher the roughness value, themore diffuse reflections will be renderedFor further information on the Raytracing settings please refer to the ”General TruelightMaterial Settings” section at the beginning of the chapter.230
