I don't know truthfully. I have never had an error with Bryce--altho' sometimes (especially when I add other things--for instance, just added Phil Hokusai's wings to several figures) they import 'grey'. HOWEVER, IF you follow Spike's tutorial, that works out fine. I'm so used to 'selecting' in Bryce and rematerializing (so to speak) that I don't even think about it. Hopefully someone else may be able to say more about the errors. You ARE saving as wave objects, right?? diane B
