Post Process Material Problem

I am trying to create a bleach bypass effect using the similiar setup like this thanks to Oliver H.M for the source. Well this is my material setup. As soon as I insert it in blendables, screen turns black. What am I doing wrong?



You need to use PostProcessInput0, which is in fact the scene color.
PostProcessInput1 returns the separate translucency only.

On a side note, you can scratch all of the bottom nodes up to the ‘ratio’ parameter, simply replacing them with a Desaturation node. (Not sure what I was doing there back in the day…)

Here’s a more lightweight version of the material (make sure to set the post process blendable location to ‘After Tonemapping’)


It worked perfectly, Thank you :slight_smile:
