HDRi skies for background, illumination and/or reflection
HDRi Skies are special images to represent skies which contain extra information about intensities of the colors.
HDRi (high dynamic range imaging)is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRi is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
IRender nXt offers support for HDRi Skies - used as visible skies, as sky reflections and for illumination from the Sky.
