I just went through the CarraraP7 thread. Interesting. Since I have Poser 4 through 7, 
I shouldn't have a problem. I did load a complex scene into Carrara and it imported just
fine, and rendered VERY well indeed. I was just checking to see how it imported, and it
has no problems. You are right though. The best way to see how this will work is to import
a poser figure, load in the Siren's hull, size it and export. Then load into Poser and see if it's
the right size. SIGH. Sometimes I wonder why the scales are always different. :) BTW, I checked
the help and located the manual. PLEASE tell me the manual is useful. Poser and Bryce 
manuals are prime examples of how NOT to do it. :) Poser 7 might have a better one, I haven't
checked it yet but my faith in 3d manuals has not been very good since most of the ones I have
are terrible.
