This question already has an answer here:

How do I vary the amount of a bump mapping effect on an object in cycles? I wanted to make a planet with a volcano using the both displacement method, but the effect displaced my volcano more than I wanted, as you can see.

  • $\begingroup$ Add a math node before the displacement, set it to multiply and by changing the values you can control how pronounced the displacement will be. $\endgroup$ – cegaton Feb 27 '18 at 20:01
  • $\begingroup$ I did that and also added a mapping node and that solved it. $\endgroup$ – FloppyJowl Feb 27 '18 at 20:40
