I'm a bit dubious Karl. The wire frames posted on his other vids don't show any signs of volumetrics, and when you look at the backgrounds they are far too detailed as in Nebulas to be created in Bryce alone. So far he hasn't argued the case as there is a thread on Daz which he posted. People questioned the ability to create the whole animation in Bryce alone and he hsan't answered or given any details as yet. Still nice animation whatever the outcome,
