Actually,..........I know it as HDRI(High Dynamic Range Imaging), wherein you use a specially processed image(HDRI or HDR) to provide a light source for your scene. Higher end apps can make use of this process, 3D Studio Max, C4D and others. See attached link for more info. You can fake HDRI in Bryce(do a forum search for "Fake HDRI") but you cannot do true HDRI. Vue 5 I does have an HDRI option but as to whether it's true HDRI, I have no knowledge. Hope that helps.
