I have this black and gold sort of paint melting cycles material. I would like to add depth to the texture using the Color ramp node. How can I create displacement using my current node setup?

My node layout:

Here are my nodes:

Here is my slightly Photoshopped test render:

  • $\begingroup$ have you tried to plug the output of your ColorRamp into the Height input of a Vector > Bump node, then plug the output of your Bump node into the Normal input of your two Principled BSDF? Is that what you want? $\endgroup$ – moonboots Jun 28 '18 at 14:19

You can use the texture as a bump map on the whole material

enter image description here

Or you can add a Vector>Bump node to add the bump map to one or more of the shaders you are using.

If you need real displacement, not just bump map, enable the experimental feature set and then change the displacement to True or Both in the material.
