Wow! - thats excellent! - you could be the Picasso of the Bryce community! :D ..sorry, couldnt resist it! (regains composure) - other than this being a wind-up!? - I am perplexed by this based on what you have said, but I have had a strange glitch which messes up the meshes when any animation keyframes have been used in objects in a scene. I have previously copied an object from one scene to another etc. and then hit the play button only to see my beuatiful constructions fly apart/shrink/explode in some insane manner. I assume you are using a 'clean' document each time!? - with no keyframe remnants etc in it!? - its a possibility! - If you can easily do so, ditch the preferences file for Bryce or even re-install it as well.
