I'm trying to use a plane with an image texture to render a topographic map of the US. When I add a subdivision modifier and use a bump only surface displacement, I have a fine looking map: enter image description here

When I try to use displacement only, however, I get this much less fun looking thing:

Is there a reason for this, and if so, what can I do to avoid it?

p.s. I'm very new to blender, so please forgive anything egregious in the wording!

edit: here's my set of settings for reference:

You have the Strength property on the Displace modifier turned up too high. Turn it down to 0.1 (or lower).

  • $\begingroup$ I'm not seeing a strength property under the Displacement modifier. I've edited the main post to include the settings I'm seeing. Can you let me know where I should be looking? $\endgroup$ – scrollex Aug 25 at 22:12
  • $\begingroup$ @scrollex Add a "Math" node in between Color and Displacement, and adjust the value until it's correct. $\endgroup$ – chirpywiz711 Aug 26 at 23:12
