I have been using the xsi crosswalk to get models transfered from 3ds max to XSI mod tool

however it seems like some models will lose their UV coorindinates. the mesh transfers properly into XSI otherwise and will export to sins except for the UV coordinates being blank (I can assign a new uv unwrap and it will work, but it is not possible for me to remap ships in XSI in any sane amount of time) It is only a few models that I have this problem on, a larger percentage come over with no problem. No amount of adding and removing UV modifiers on the max side seems to fix it.

has anyone else had this problem with the crosswalk?

I can't use .obj because max mangles texture coordinates, fbx is broken, 3ds has no binormals. Any suggestions on how to consistantly get models converted?
