RGB Image (Color Image)

RGB Image texture is used to connect an external image file to any material parameters that accept a texture map (Figure 1).

Figure 1: The RGB Image node is being used to import a PNG image into the DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. pin of a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters..


To create an icon of the image click on the eyeball icon in the upper right. The drawer icon is used to replace the image, the circular arrow reloads the image and the filmstrip icon allows you to load an animated sequence.


The RGB Image texture will convert all images to three channels including images that are greyscale. To use memory resource efficiently only use the RGB Image texture for color inputs. For greyscale channels such as bump use the Greyscale Image texture.




Controls the brightness of the image, lowering the value will cause the image to appear darker on the surface.


GammaThe function or attribute used to code or decode luminance for common displays. The computer graphics industry has set a standard gamma setting of 2.2 making it the most common default for 3D modelling and rendering applications.
Controls the luminance of the input image and can be used to tune the image or color correct the image if needed.


These settings can be used to position, rotation, and scale the texture on the surface.


Inverts the color values of the image.


Input accepts an Octane projection node. If nothing is connected to this input the image texture will use the surface’s UV texture coordinates by default. Projection nodes are described in the Octane Projection node section of this manual.


Border Mode
Sets the behavior of the space around the image if the image does not cover the entire geometry. The default behavior is Wrap around, which means that the image is repeated in the areas outside of the images coverage. If set to white or black, the area outside the image will be white or black respectively.
