They were pretty useful (or 'are' if you sometimes use MR)

You could 'transmit' different versions of settings like colors, toggles, levels, that drive existing shader paramaters  in different 'channels' (hence the name)
going to receptors where other nodes are plugged-in those receptors anywhere in the scene, outputting the result of whatever you plugged in as if that something else in the scene using a given channel had different settings.
say if you wanted less light samplig for your fog volume,

And very good for ray stwitching where you could have entirly different settings for what was seen by secondary rays and such.

The applications were very wide varying.

I have the sources for MR/Arnold somewhere on an old HD.

Your'e saying Stefano also made an Arnold version?

I don't think that would exist for another platform. We used those years ago and were, if I remember correctly, some shaders created by a Softimage dev.

Anyone out there have this or one called sj_station? The link on rray doesn't seem too work? I'm working on porting assets too maya and this shader is missing.

Any chance this same one exists for maya/mental ray?
