I'm talking of stills of course, as you can't animate with Bryce Uhm, sorry, but yes you can. Animation has been part of Bryce since version 3. I use it extensively in my work. There's even a rather famous (within Bryce circles) film called "Interplanetary Traveller" that first demonstrated Bryce's animation capabilities.
