Ramp
What is it about?
This page covers the Ramp node of the Redshift renderer in Cinema 4D. It maps an input coordinate onto a color gradient — driving color transitions from UVs, positions or any scalar; for pure values the Scalar Ramp is the counterpart.
This shader node maps an input coordinate to a color gradient. If you only want to output a floating point value, you should look at the Scalar Ramp instead.
