maxxxmodelz, not everyone who uses Bryce has a 'purist' approach. And it's only a fun thing, anyway.

It probably started as a response to the dreadful 3D snobbery Bryce users suffered at the hands of people who regarded themselves as 'serious 3D artists' (mostly users of pirate copies of 3D Studio Max). A sort of sport developed in being able to do amazing things with this supposedly 'toy' program.

There are different types of 'purism', too. Brycers like draculaz and Ornlu have a fairly deep preference for doing everything themselves, rather than using the work of other people. They don't mind non-Bryce stuff, so as they created it. Bloody slackers, mind you, for using a program somebody else wrote. ;-)

My little purism sadness is to do as much as possible in the Bryce render, rather than post-edit in another program. There's no sense to this at all. It's just for fun.
