A remake of a scene [link]
made in 2007 and rendered in Bryce 6 using many conventional radial lights.
This scene updated today, rendered with three TA optimised gel lights driven by a spherically mapped ( Spherical Mapper
) capture of the HDRI backdrop and one blocking gel to isolate the TA rendering from the IBL backdrop which drives the reflections. Bryce sun provides specular only to drive material specular response. In essence the same approach as taken in this video Bryce 20 minute scene lighting project - Using IBL with boost light and TA gels - by David Brinnen
