Getting Different Results in Blender 2.8

Excellent tutorial.  Followed along with this in Blender 2.8 and got different results with both Eevee and Cycles though.  I'm not using the supplied file, I just tried it with a geosphere.  I tried your file and it works in 2.8.  Can someone tell me what setup I need to get this look from scratch?
