They seem to be still operating under the assumption that Bryce is automatically the final destination where you will do all rendering and that everything will be Imported rather than Exported. For some (like me) that's actually true, as I will never be able to afford the higher priced programs, but for a lot of others it just 'ain't so. Even for me, though I expect Bryce will probably always be my final destination where I compose the scene and render, it would be nice to be able to export something that needs changing so I could make structural adjustments to it in say, Amapi & then re-import into Bryce. Oh well, maybe one of these centuries they'll get it all right.
