I seem to recall that my first cr2 prop (a gun with working slide or something) I used the Poser4 fish as a base. I did have some problems with one of the propagating channels until I removed it, tho. I like PhilC's idea, tho...especially the implied suggestion of making a mock-up character from primitives (using the Heirarchy Editor's functions) and saving that cr2 to use as a base.
