Well if they're sensible about it, they'll make all material and environment parameters scriptable. If they do that, "automated" light-synthesis will be possible in Bryce. At the moment, it's possible (believe me), but it's far from being automated :-(

I hope the do include scripting, that one goes waaaaaaaaay up top, on my wish-list :-D
