I would like to learn how to use part of an image texture and convert it into a material in cycles ( not sure that is even possible).
So my example is the following:
I have an image texture which is a white marble with black veins applied to a sphere.
I have used the same texture as a displacement to create the ridges in the sphere.
Now, I would like to convert the black veins/ridges which is an image texture, into a gold procedural material.
How could I achieve that?
Could someone be so kind to teach me the node set up?
Thank you very much!
