It is good for Bryce but really for Bryce only. (maybe soem other landscape programs)If you could export them to another program you would have a very high poly mesh that would be difficult to render. So what is good for Bryce is not always good for another program. Generally they woudl be fine for other Brycers to use as well. But outside of Bryce not so useful.
