N and K values

Is it possible to have the N and K values in Maya, as shown in the Metal material scripted node:

http://render.otoy.com/forum/viewtopic.php?f=73&t=43973

'For metals you may also find an IOR, for instance you may find Gold has an IOR of 0.47. This number alone is useless, as metals have a complex index of refraction. You should get two values, called N and K. These are the real and imaginary parts of the IOR. For gold these values are around 0.47 and 2.25.'

cheers.

Just wondering if there is any news on this.
So I know whether I need to take projects in to Standalone.

cheers.

yeah, this would be nice. right now it's just a crap shoot getting the materials setup correctly.

Real world N K would be a nice feature. More realistic metals is something I'm interested in.

Hi Jim,

I might need this feature in an up coming project.
Can you at least indicate whether this is possible in Maya.
Same goes for the displacement from procedurals (seriously thinking of hopping over to C4D, if not).

cheers.
