How can I do the Screen layer effect of Photoshop in the Material Editor? I have two nodes I need to combine, but I need to set my top node to screen over my bottom node. Any ideas on how to recreate the screen effect? Thanks!
No. Add isn't overlay. If 0.5 is halfway between white and black, Overlay seems to take everything over 0.5 and adds it, and anything below 0.5 and subtracts it. The way the math nodes work is with basic math :P You add a pixel of 0.15 brightness to another with 0.35, you end up with a mid-grey pixel of 0.5. Multiply,…
Some of the notes I made for the nodes just to refer to them in a photoshop-ish way for me to understand :) Add = Screen Multiply = Multiply (doh) OneMinus = Invert Power = Contrast Clamp = Limit Dark/Light Min/Max value
Lerp which takes the inputs of your two nodes or textures and a constant one vector with a value of 0.5 should do the trick. You can modify the constant one vector for how much you want to screen A value of 1 means that A is now 100% transparent/opaque and a value of 0 is B 100% opaque.
