Hello everyone !
I know this can seems simple, but I’m really struggling with something.
I want to make some trippy effects, and for that I need to have “Post Process windows”.
What I mean by that is a plane like this :
Through which we can see, but applying a post process effect on everything behind.
Let’s say I want to make a windows making everything behind it negative.
I tried different things :
- Doing it with localized postprocess :
But the solution seems not very practical, I need to be able to move the window easily. And it’s just inversing the colors of the textures, the sky doesn’t appear negative when you look through the area or when you’re in it.
- I tried to use Custom Stencil :
But all I could do was to inverse the color of the window itself, and not what’s behind it. I also tried to make the window transparent, then applying the post process effect but I that don’t work.
- I finally tried to use Translucent Material, which seemed to be the closest to the solution. That allowed me to access to the diffuse color.
But it’s not the same as PostProcessInput0, and if I try to inverse that the result is just disapointing.
I would LOVE to have access to PostProcessInput0 right there :
But that’s only working for a post process material, and the solutions I found with post process were not as close as this one.
If anyone have any idea for a new lead, I would gladly take it.
I really though making that effect would be very simple, but I’m struggling with that for some time now …
