Smooth Pixel Perfect Camera prototype - Unreal Engine

I'm working on a method to get Smooth Pixel Perfect on 3d rendering for unreal engine.

On the left you can see a normal pixel art effect, achieved by rendering the scene in low resolution and then upsampling without any anti-aliasing.
On the right the result after applying Smooth Pixel Perfect to erase the flickering pixels and get sprite looking assets.

This is impressive, I read on reddit that you are planning on releasing this later on epic, I would like to ask for explanation on how it works but regardless I'm really looking forward to it :D

Do you have a tutorial on how to create the pixel graphics? really cool look

[KramGamesOfficial]

Still planning on releasing this? Love it!

There is still no solution for shadows with an orthographic camera in Unreal Engine right?

How do you achieve both smooth world and the smooth follow of an object? so far ive only figured how to make the world smooth

[МихаилВерьет]

I'm looking forward. Are you still planning to post this method in the store?

amazing! I tried to get it working in my game but it doesnt seem to allow rendering of sprites/flipbooks. also no matter what i did i couldnt get it working on my own character. is it possible youd be willing to make a how to integrate it into your own game with different assets?

Are there any project settings you had to turn off for this to work? I turned off AA and motion blur but I still feel like something in the engine is fighting me.

How to remove noise when moving? its fine when I move up and down, but not when I move left and right, or camera moves
