Wow...awesome feedback. I'm glad to hear most feel FireFly (at the expense of render time) is detectably capable of more subtle shadows/reflections (whatever the backend antialiasing or sampling rationale). I also am hearing confirmation of: 1) render quality being largely about general lighting skill, and 2) a perhaps cumilative and expected effect of various factors on render quality(use of features like displacement, highest quality models such as V3/M3 rather than V2/M2, higher resolution image maps and the aforementioned attention to lighting, among any number of others). Again, wasn't sure the question had a fair answer, but your many responses have been pretty illuminating (bad pun). P.S. I orininally asked the question because I saw an online ad offering Bryce 5 (full) for like $69. I've been impressed with the realism achieved with the newer Bryce, kinda for how it handles light/shadow, and it got me thinking about whether it made sense to keep aiming toward P5 (I know, I know all very different features/functionality in Bryce). Thanks Again All, pdog
