Bitmap rgb value as a Cd attibute ?

[Vorkosigan 3]

hello,

 

I am driving scale value through a Cd attribute to populate Geo along an object (the one having a ramp bitmap / ramp) and I basically need to get those bitmap / ramp RGB value in my Cd at the end of the pipe before my copy node.

I succeeded with a basic paint node but I am stuck with the bitmap / ramp approach.
So to make it simple, the Paint node doesn't do a clean enough job for me, too messy in the look it gives me.

Any tips and help would be more than welcome.

 

Thank you,
