The Multilight feature removes the need to re-render images when light changes are required; instead you can simply adjust the lights in real time. Multilight™ allows the user to change intensities of individual lights and multiple scene emitters during and after the rendering process, eliminating the need to run various renders to tweak the lighting set up. This gives you infinite possibilities and you can save numerous different lighting versions of the same scene without rendering it over and over again. It is also possible to make a Multilight video with the lighting conditions changing over time.

This feature is the first of its kind in a commercial render engine and it is extremely powerful.
