hello, I'm working with a vendor who's delivering their groom files back to me in maya.
  The file does not open without crashing but it supplies a few errors before crashing:
  \ephere\geometry\native\Matrix.h(280):
Assert failed: Ephere::NearEqual( directionLengthSquared, T( 1 ), T( 1e-4 ) ), Vector [-nan, -nan, -nan] has length squared -nan, which is not close enough to 1
  
and \Ephere\Geometry\Native\PolygonMeshQueryContext.cpp(19):
Assert failed: polygonIndex != -1
  
It could be a version issue but i'm not sure, My version is 3.2.0.27311 
the vendor is saying their version is Ornatrix-3.2.8.28851
  i'll also post this in the forum and hopefully i can get a response there as well.
  Thank you
