7.1 Truelight Materials» Roughness Texture The Roughness texture allows you to control the material’sroughness. If the roughness texture is enabled the default roughness sliderloses his functionality. Instead, you can define a minimum and maximumroughness. The minimum roughness defines the roughness value that is mappedto the value 0 of the texture image. The maximum roughness defines theroughness value that is mapped to the value 1 of the texture image. ForIsotropic materials the red color channel will be interpreted. This allows theusage of a grayscale image. For anisotropic materials the red color channel willbe used for the roughness in U and the green color channel for the roughnessin V.» Use Texture: Loads an image texture for the bump color channel. Uses theimage as pattern on the surfaces.• Repeat Mode: Sets the repeat mode of the texture. There are four modes,which can be set:· Repeat: Repeats the texture in all directions. Repeat· Mirrored Repeat: Repeats and mirrors the texture on the x- and y-axiswith every repetition.· Decal: The texture will not be repeated.· Clamp: Repeats only the last pixel of the texture will be repeated.• Link Repeat Modes: Uses the same repeat mode for v-coordinates as forthe u-coordinates.• Anisotropy: Sets the texture filter quality for the image texture. 1 is lowestquality. 16 is highest quality.• Minimum Roughtness: Defines the roughness value that is mapped to thevalue 0.• Maximum Roughness: Defines the roughness value that is mapped to thevalue 1.» Bump Texture247
