I am trying to make a hillshade of a terrain. The issue I am facing is that the model looks dull as like the default models available in blender. I am attaching the screenshot of my workspace and nodes.

The tutorial which I followed is https://somethingaboutmaps.wordpress.com/2017/11/16/creating-shaded-relief-in-blender/
