At least I know someone would be interested in the tutorial I'm working on, hehe. Actually Bryce does have some good uses which always keeps it in my toolkit, even though I render the majority of my stuff in Carrara. I will be sure to post a link to the tut. No worries about using an older version of Bryce.
I'm using Bryce 5.5 to do this, 'cause I believe material and terrain animation was broken in Bryce ver. 6. Hopefully they've fixed it by now.
Cheers, Edmund
