The Octane Float Image Texture node converts an RGB image to grayscale. This can conserve RAM when using a color image as an input for bump or opacity channel of an Octane material. The Invert checkbox can be used to invert the image (useful for bump and opacity maps.) Figure 1 shows a red fractal texture used as a Float image texture connected to the Diffuse channel of an Octane shader. The result is a grayscale cloud texture that appears on the shader ball.

Controls the brightness of the image, lowering the value will cause the image to appear darker on the surface.
Controls the luminance of the input image and can be used to tune the image or color correct the image if needed.
Input accepts an Octane transform node which can be used to adjust the position of the image on the surface. These nodes are described in the Octane Transform node section of this guide
Sets the image number based on frame for animated sequences
A control to allow for time offset in animated textures.
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.
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.
