(autokey!!)ok. you're on the right track. now seperate out the sugguestions because as you can see everyone has a different way of doing this. second decide if you want to physically rotate the object or just rotate the material texture. you should now have enough information to be able to do this either way. start a new bryce file that concentrates on just the rotation problem. go back to the previos sugguestions remembering the autokey setting that you used and experiment.
