First: I haven't checked your stuff yet.

But I do use Hexagon as my primary modeler, and I was thinking that it might be better if you simply offered the models as raw obj (scaled to V4/M4) - that way a Poser user could easily import them as obj with ALL THE IMPORT OPTIONS unchecked and still have a correct-sized model. It's easy then to save it as a Poser prop by simply clicking the + in the Props palette.

Oh and keep an eye out for Computer magazines that may have earlier Poser versions on their cover disks ;)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
