I am having an issue where I am trying to transfer my weapon from blender to Poser 10 and I get weird shapes in poser that don't match the figure in Blender.

Blender with weapon:

Then I make it an object using wavefront.

Poser 10 with the weapon imported from Blender, as you can see it does not match the blender image.

Why is Poser 10 doing that?
