the only real problem with pants is that the standard poser zero pose is unsuited for modelling anything with seams in the crotch -- if you use the "da vinci" pose instead, the one with legs spread, it becomes a lot easier; you can use the same techniques you use otherwise (i see the latest DAZ hexagon tutorial uses lofting; that should work just fine). this is no issue for dynamic clothes, since you can wrap them around a figure in any kind of pose. but you'll possibly have more of an issue conforming the new model -- since i've never yet done that, i don't know what's involved.
