Try this Calico . After Poseray as you see!
I think the polygons with more then 4 vertices causes problems (Ngons? They are problematic most of the time).
You can tripple the model in LW as the basic way but it creates sometimes very bad made objects (from a polygon workflow) .
You can-must cleanup the model after. There are other ways too maybe.
I like Poseray it is sometimes a life saver
Edit: I only used "Recalculate normals" in the "Groups" tabs in Poseray. Crease angle (deg) was 10 (don't know if this is the default or one that i put in there).
