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?
Recreating "Overlay" blendmode in /mat nodegraph?

The ‘photoshop’ blending modes are of limited use in shader building. Blend modes such as overlay only work correctly in gamma space, with 0-1 image data, whereas shading in mantra is in linear space, with possibly unbounded values. If you feel that you may still get some use from them, the w3c has code and examples for all the common blending modes in the SVG documentation.
Edit:
I'll try to see if I can find it again, later.
