(mix color) bias amount based on a certain value?

Recommended Posts

I want to mix the color output of the ramp with the color output of another ramp based on a certain color range. For example, the second ramp should only mixed in if the Cd value of the first ramp is less than 0.1 (the whites only). So I thought it would be possible with the color mix node but I don't know what variable to put in into the bias amount. Or is there another way?

You can use the Luminance VOP and use your first Cd, and then plug the result into bias.
