Sci Fi Hull Materials
I can only get the displacement feature to work in cycles and not Eevee...
...this displacement feature is currently only supported in cycles unfortunately :(
I can't get the cycles displacement effect working. How do I do this?
Under the Material Properties tab, go to Settings -> Surface. Once there, you will see a drop-down box called Displacement. Change this to Displacement Only or Displacement and Bump and you should start seeing displacement in the viewport.
I'd like to change the effect slightly. How do I get inside the node group to do this?
With the node selected in Blender, press the tab key. This will open up the node group for inspection and editing.
Is there a way to convert the texture to a normal map that could be used in Unreal Engine or in Blender's displacement modifier to change the actual mesh?
There is a video tutorial here that may be useful:

This should produce a displacement map that you can then use to be imported into other projects.
