I have been playing with the new exporter for Blender 2.6x, and I have to say it's quite nice, and will allow me to retire the older version of Blender. I was able to make the old export engine export to most all the blueprint formats I needed, save one: viewer-facing flora. I went through extensive testing at the time, and tracked it to a single parameter in the IGS stream regarding the viewer facing value, which can be one of three things: none, viewer, upright viewer. In my case, it's the TrainUprightViewFacingFlora.fx, and the exporter automatically sets the viewer facing value to 2 = upright viewer facing.
This causes the blueprint editor to crash with the attached error. If I change the shader in slot 1 to something basic, like Tex, the export works, but the resulting geometry is then incorrect. I am testing a single plane mesh with an image texture in slot 2. The plane is centered at 0,0,0 and faces the positive Y axis.
Any advice would be deeply appreciated!
