rtg format in Maya

Did someone try to load stuff from the rtg format. It’s pretty cool, because it’s ASCII and contains all the matrices for pivots and other transformation stuff. My biggest Problem is : The geometry seems destroyed when i load the format. There are some Problems with the Normals it seems. The Faces also don’t look right.
I compared the faces to the obj format i used recently and i found out, that the faces have totaly different indexes. What’s about this format ? Is it damaged ? And why can’t i export the lights ?
Hope some1 here used the rtg format.

I suggest you go to a Maya-specific forum. Your question has nothing to do with OpenGL, so you’re unlikely to find good help here.
