What I meant by a 'reliable' exporter was simply this : one that gives you TRUE WYSIWYG between Max and Blitz.
The problem is that Max on it's own isn't giving you true WYSIWYG. Max hides the problem from you, and it's only when exporting ( properly ) that it shows up.
By means of an example : Create a simple object, convert to E-Poly. Mirror a copy of it. Now delete a couple of faces and put them back in. You know how you always have to build your faces/polys by going through the vertice in an anti-clockwise fashion? Surprise!! Now you have to go through them in a clockwise fashion. Because the mirrored section is now inverted. It just doesn't show that it's inverted until you reset XForm.
