heyas; well, i don't consider morphable props to be posable... they're, well, morphable. :) of course, SOME poseable props are two parented props that rotate around their hinge points.... actually, a pp2 usually contains all the object geometry embedded in the file, while a cr2 usually just points to an outside obj file. depending on the size (# of polys) of the object, the pp2 can be larger. of course, figures are usually larger than props, so it might break even in a general comparison. also note that it is possible to point to an obj with a pp2, rather than embed it. if you got any freebie zygote props, some of them work like this.
