9.1 Truelight Materials» Roughness Texture The Roughness texture allows you to control the material’sroughness. If the roughness texture is enabled the default roughness slider loseshis functionality. Instead, you can define a minimum and maximum roughness.The minimum roughness defines the roughness value that is mapped to the value0 of the texture image. The maximum roughness defines the roughness valuethat is mapped to the value 1 of the texture image. For Isotropic materials thered color channel will be interpreted. This allows the usage of a grayscale image.For anisotropic materials the red color channel will be used for the roughness inU and the green color channel for the roughness in V.» Use Texture: Loads an image texture for the bump color channel. Uses the imageas 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 Texture» Use Texture: Loads an image texture for the bump color channel. Uses the imageas pattern on the surfaces.299
