I'll upgrade to Bryce 5. Sure, why not? THe renders from Bryce never dissapoint even if they are a bit slow. Also, the Tree genrator is a nice addition (but where's the GRASS!?! I need GRASS!) and the fact that there are metaballs included in B5 is just an added bonus. You can create your own alien type lifeforms or plantlife with those. Perhaps it's not the "Be all and End all" but it's still a fine program. Now if they could just include support for Poser files directly (anims and all).
