I was trying hard and i failed. It was simply impossible for me to export a mesh 1:1 from MAX to XSI.
When using the DotXSI pluging, the mesh was completly destoyed, trying the demo version of Deep Exploration gave me better results, but the mesh was not exactly the same.
I also tired the max to obj plugin (http://www.habware.at/duck4.htm)
The MAX scene can be downloaded for free at http://www.3dluvr.com/pepeland/Misc/ciceto1.htm
To get a low poly of the objects, mesh smooth and subdivision should be deleted.
I posted the mesh how it should be here (pic at bottom of page, sometimes takes long to load):
If you know how to do it properly, it would be GREAT if you could mail the transformed mesh to firstname.lastname@example.org
