Open your Blender 3D and remove the default cube and add a plane.
You can use the default cube if you want.
Go to the main menu and select the Shading tab.
Using the keys Shift+A and Search option add these nodes to your 3D object (plane or cube).
Link with the mouse by drag and drop each node and change values like in my screenshot.
Don't forget to save the blender file with the keys Ctr+S.
