I've seen a very limited success of Poser 5 hair exported to other 3D apps (with not so great results), my question is will it be possible, some day, to export the Poser 5 hair correctly? Is it physically possible to do this and they just haven't gotten around to a plugin, or is this not possible with the type of software we have today?

heyas; the p5 hair exports lines instead of facets. if your 3d app can read, dispay, and/or render lines in an obj format, you should be fine. otherwise, you need to convert the lines to facets, which means each hair becomes a closed polygon with its end connected to its root. which can be somewhat of a mess. hmmm... i can't remember at last count if the exported hair had all its hairs, or only the guidehairs. anyway, lines are apparently legal obj 'things,' so....
