When I export a scene that utilizes Out of Core memory to an ORBX from Lightwave, I get these weird glitches. I can't exactly tell what the problem is, but in the past it looked like textures were turned off and on, although it doesn't look like that in this case. The ORBX export is extremely slow as well, while according to Lino Grandi, it should be very vast like it does in Blender.
