One of the things that's going on is that you're losing some or all of
the normals in the conversion process. If you convert the model directly
from the 3DS file using PoseRay, you'll preserve the normals and get
smoother shapes.

There's something else going on as well. The geometry I get via PoseRay
just looks like a smoothed version of what you get. It's not the same as
the geometry of the comparison image.
