No Luminance – No luminance is calculated. Direct Light – Calculates – Calculates luminance from direct lighting. It creates a grayscale mask over the points of objects lit by direct lighting. Diffuse Light – Calculates luminance from indirect lighting (GI). It creates a grayscale mask over the points of objects lit by indirect lighting. Direct+Diffuse Light – Calculates luminance from direct and indirect lighting. This creates a grayscale mask over the points of objects by direct and indirect lighting.
Samples – Specifies samples for diffuse lightning.
ContributetoGI – When – When enabled, the direct light contributes to the GI calculations. The effect is visible only when the texture is used for diffuse calculation with either the Diffuse Only or the Direct+Diffuse mode.
