Maya 2012 mental ray rendering crash

Maya was crashing when I tried to render on the school workstations. After way too much troubleshooting, I happened on this blog at Autodesk, indicating that Maya 2012 will crash when rendering with Mental Ray when encountering a luminance node linked to a bump node.

As you can see from the image, I had an offending luminance node in the bump for the rust part of the layered rust image of a rusty metal shader network from Maya 2012

The good part of this is that the troubleshooting led me to clean up and rename parts of my shader network.

I really appreciate Autodesk’s online documentation of this bug – without that, it would have taken me significantly more time to isolate.
