I’m not too sure how easy what I want to achieve here is, or how possible it is (though I assume it must be as most things in UE4 are!).
I have a scene which I have applied a post-processing effect to with a LUT to make it all appear black and white.
Within in the scene I have a big glass object (essentially a large looking glass).
When the player looks at/through this glass object, everything the other side of it appears in glorious bright colour, while the world around it appears in B&W still.
I thought I might have been able to achieve this with multiple post-processing volumes, but it appears only one works at a time and can’t be applied to just a single object/part of the scene.
Is there a way to achieve what I want here and how?
