RGB Image


RGB Image textures connect an external image file to any material parameters that accept a Texture map.

The RGB Image texture converts all images to three-channel images, including greyscale images. To use memory resources efficiently, use the RGB Image texture for color inputs. For greyscale channels such as Bump, use the Greyscale Image texture.

Use the Import settings button (Figure 2) to indicate the preferred channel format for loading the image. This is ignored for 8-bit images. You can also use this for selecting the texture bit-depth of High Dynamic Resolution images in Environment textures.
