Here's the settings I used too, if you want to check them out?

First is the object after I had exported it out as a 3DS (Max) format and then imported that object right 
back into Poser and THEN exported it out again but this time as the OBJ (Wavefront) format.

And finally, you can see the results in the Ivy Gen program :)

Hope this clears things up and actually, I am totally glad you brought this subject up, 
cuz other wize I might never have thought about it, since I have several 3D programs 
I work with, it wouldn't be an issue for me, and it never occured to me that some 
people might only have one kind of 3D program, be it Poser or what ever 
else and they would have these problems then, so thanx!
