spectral rendering

[justin2869]

I have read mixed things about mental ray's spectral rendering capacities. Is it possible? Do you have to write your own shaders?

I know it's possible, but I am not familiar with it. I haven't seen much info on it, so I would imagine it would be difficult to locate pre-written shaders out there.

Mental ray has some hidden shaders that can be un-locked as well as some workarounds that may get you closer.
