EverPaint
I don't know how to plug in the nodes.

The float effect doesn't work in Evee.
Just make sure to switch on "alpha hashed" for Blend and Shadow in the Settings of your Material Properties.
How do I get started?
After opening the EverPaint.blend you will see the demo object. For this object I made several example materials. Just check them out, to get some ideas of this powerful shader.
