Adding user data to Corona Materials?

[caspian]

Is there a way to add user data to Corona materials?
I've been watching this tutorial that makes use of Scene Nodes at the point linked below he links a black and white noise material to a Redshift 'Display Colour' so the colour matches the bw noise (I think I've butchered that explanation!) Is there a way of achieving a similar thing in Corona so the colour is mapped to the noise?

This is as far as I have got but I'm scratching my head as to what to do to with Corona material: https://www.dropbox.com/s/fa1k9mqoxxcwq1z/Torus%20nodes%20clones%201.c4d?dl=0

Hi Caspian,

What specifically did you want to add to a Corona material in terms of user data? In this in regards to Cinema node system at all?

you can use the c4d colorize shader to map any colors to an bw noise or gradient etc.

you and also use the display color shader in c4d to rebnder the c4d display color, which can again be driven by something else (scene data).
in most cases this renders also fine in Corona due the great interal c4d shader support Corona offers.
