Im' truly enjoying Bryce 6 and experimenting with HDRI and trying exporting boolean objects into other applications. I also will be going over AS web links to better understand Bryce's HDRI re quirements. As far as modelling, on parts of a model I made in 5.5 made it to the other apps partly because it's set up differently than what Bryce 6 requires, but it still works! The rendering is much faster, making Bryce 6 that much more enjoyable to use. I recently upgraded from a G3 to a G4 Dual Processor, 2 GIGs Ram.
