I've NEVER had a Poser figure come in at the correct scale no matter what I do if I export them (which is sometimes nice for instance with V4 and her bend feet)

I had some problems when I started with Hexagon I had some problems with importing DAZ-obj files, but I found something that worked: The way SSAfam1 describes is the way I do it, but when I import the obj-file in hexagon, I set the scale to 100 and textures Y-flipped.
After I made my clothes (or other objects) in hexagon, I export them with scale set to 0,01 (european) and texures Y-flipped.
I always got reasonable results this way.

The main problem with Poser obj-files and other modellers, is that Poser uses a ridiculous large scale for their standard units, so they are imported very small, I also had this problem with rhino.
No matter, what preference unit you use, Poser obj-files are always exported at poser-units scales. And how this scale is related to real-world units ( meters or feet, whatever) is a very old subject of discussion.

best regards,

Bopper.
