Hey, thanks for confirming that!
I've been meaning to get around to installing 2012 but I've been caught up in other things. This is going to be some fun debugging, I'm sure...
One query; is this with pre-triangulated meshes, or meshes with quads/ngons? I'll be the first to admit that my code is possibly not working entirely as expected but to the best of my knowledge I just list mesh data exactly as provided. There is, however, an exception to this: I do
perform a rough triangulation pass using the FBX SDK if a mesh isn't already triangulated. I would assume this uses a similar algorithm to whatever CryMaxExport does to handle quads, but it's worth me investigating.
