Hi tupu, some of the older FBX import translators had bugs in them though, so you may run into some problems particularly with n-gons if you cannot update from the stock FBX importer plugin.

But you may be able to avoid issues by using "Output:Quads & Triangles" when exporting from MoI.

They do have an archived plug-in available for Viz 2008 available here:

But I can't seem to find one for Viz 2007 though.
