There are plenty of freebie large scale sci fi ships that could easily be converted to poser. I can't really think of many I haven't got sitting here on my HD already. ;) Since most large scale ships have no moving parts, it's more a matter of seeing how any image maps were applied, and if they can be applied properly in Poser. UV maps of course wouldn;t present a problem, but I know some of the trek ships use planar and cylindrical mapping. I think scale is sort of a moot point for larger items anyway, because you have a scale dial in poser anyway. Just scale it up or down as wanted for the shot. Imagine trying to find a vicky3 model, with a galactica full scale in the scene!

Way too many people take way too many things way too seriously.
