-----> Octane Float Image Texture

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.
