Glossiness – Controls the sharpness of refractions. Scenes with lots of reflective and refractive surfaces may require higher values to look correct. Max depth – Specifies the number of times a ray can be reflected. Reflect – If a ray has reached its maximum reflection depth, this color is returned without tracing the ray further. Useful when the ramp offset texture has values in range but the user wants values in range instead. Output Offset – Specifies an amount used to offset the ramp position by a static value. Ramp Offset – Specifies a grayscale texture used to offset the ramp position for the respective shaded point. Position 0.0 maps to light intensity 0.0, position 1.0 maps to light intensity 1.0 and above. The Diffuse Ramp controls the diffuse color based on the amount of light received.
