...REALLY NICE!

Yes, it may well be that Bryce needs a further revision of its rendering engine to take full advantage of this type of lighting. That's one of the reasons why I would HOPE that Carrara 6 will be able to host Bryce scenes...and why maybe Bryce 7 will basically need to add the same render engine that Carrara uses...

I know that Vue has had its render engine revised at least 5 times- its a big effort... least with Bryce under the wing of the DAZ Eovia programmers, they should be able to get Bryce 7's render engine fully up to speed... in the meantime, mult-pass rendering might be a good solution to use...
