Recreating "Overlay" blendmode in /mat nodegraph?

Recommended Posts

A simple question perhaps - I am getting my head around the nodes representing "blend modes" in a shader:

One of the most useful blend modes in Photoshop, Mari etc. is Overlay.

How do you guys recreate "Overlay" in a node graph where you only have Add, Subtract, Multiply or Divide?

One übershader I built quite some time ago had the major photoshop blend modes between layers. At some point I extracted the combine block for someone, I'm not in front of Houdini but it should be in the attached file ;)
