9.1 Truelight Materialsequals the angle of reflection. Since a surface is usually not perfectly smooth, theorientation of the normals varies, thus creating a glossy reflection.» Roughness: The roughness parameter defines the microscopic roughness of asurface. The higher the roughness value, the more diffuse the glossy reflectionswill be rendered.» Diffuse Backscattering: Defines the roughness of the material’s diffuse component.A value of 0.0 means smooth (Lambertian surface), a value of 1.0 meansvery rough (e.g. concrete).» Diffuse Texture» Use Texture: Loads an image texture for the diffuse color channel. Uses theimage as pattern on the surfaces.• Use Alpha: Uses an alpha channel of the image texture if it has an alphachannel embedded.• Repeat Mode UV: Sets the repeat mode of the texture. There are fourmodes, which can be set:· Repeat: Repeats the texture in all directions. Repeat· Mirror: Repeats and mirrors the texture on the x- and y-axis with everyrepetition.· Decal: The texture will not be repeated.· Clamp: Repeats only the last pixel of the texture will be repeated.• Repeat UV: Sets the number of repetitions for the UVs.• Offset UV: Sets the offset for the UVs.• Rotate: Rotates the UVs.• Anisotropy: Sets the texture filter quality for the image texture. 1 is lowestquality. 16 is highest quality.• Input Gamma: Sets the texture image gamma correction.265
