Caligula's Puss Reboots has exportable primitives that you could use to substitute for your Bryce primitives - it's a pain in the neck - you have to manually substitute her torus for each one of the shell's toruses using copy/paste matrix - but it's one way to get stuff out of Bryce and into other programs like Carrara. Let me know if you need the link to her site - they might even be in the Bryce Free stuff section here at Renderosity. Jade
