This is QUITE interesting to me. I missed the upgrade price that DAZ had from Bryce 5 to Bryce 5.5 (thinking surely Bryce 6 was soon to come!). Just now looking I see that I do only have version 5; not even 5.1. How could I get the upgrade to 5.1? And on the original topic... WHAT EXACTLY does version 5.5 have that 5.1 does not have?
