How do you create procedural bubbles on a surface? I'm trying to achieve the answer in How to create procedurally generated surface bubbles on a liquid I'm unsure on how to do this in 2.9.
Here's a setup for both large and tiny bubbles :-)

Create a plane or a subdivided circle
Enable Adaptive Subdivision to use microdisplacement
Set Material Displacement &gt; Displacement (only works in Cycles)
