Well, now that the initial hype about HDRI actually being supported by bryce 6 seems to be an official fact I think its time for me to ask some questions about it....

If I understand correctly Bryce6 accepts HDRI reflections as well as IBL. Other programs that render with HDRI have both the reflections and IBL also and it's not unusual to control these seperately. Obviously a high res HDRI will create nice crisp detailed HDRI reflections, but apparently in bryce 6 higher resolutions also increases rendertime.

In other programs high-res HDRI can create rather unappealing lighting situations so it's prefered to use low res and/or heavily blurred HDRI for IBL because it gives a softer lighting setup.

To get the best of both worlds in other programs its not unusual to use a high-res map for reflections and a low-res map for the IBL. Does Bryce 6 allow for this also? Do blurred or non-blurred HDRI's affect the look of the IBL? Does the resolution of the HDRI affect the results in terms of lighting? Can seperate HDRI's be used for HDRI reflection and IBL?

Also, there's already been some other tool in bryce since version 5 that can be used for realistic lighting, known as True Ambience. Does the HDRI and IBL support work well (or at all) in combination with TA? And on the performance side, does TA seem to be faster in B6 compared to B5 and 5.5? and how does IBL affect TA performance?
