Wasn't this another patent thing? Mental Images (and now nVidia) hold this strange array of patents on somewhat odd things. I know that MentalRay's edge-rounding shader is patented.
I've worked with assets from one studio coming to us converting from Max to Softime for Arnold. Edge creasing was horrible because it didn't carry over in the models. Obviously if you have end-to-end control of the pipeline it's not too bad but any transfer between packages (Zbrush, 3DCoat, Mari) gives me the heebie jeebies.
