It might be the default post processing. try adding an infinite bounds post process volume to the level and see if it has any settings that can control that filtering effect. No idea. Maybe there is a rendering setting for it too. I didnt even know you coukd reduce the resolution like that. Thats cool!
Can you do it only on the camera viewport and not on the UI? I want to be able to have it not affect the UI
Hello. I want to make a PS1 inspired game and with that comes low resolutions. I want to use the command r.screenpercentage but when I go to a value of 10 and disable all AA, it uses a filter on the screen. Is there any way to disable this effect?
Hello dscottwilson,
I made some assumptions and would like to direct you to this article of the ue4 documentation:
The command you’re looking for is probably: ‘r.Upscale.Quality’.
I would recommend you to read the article though.
Here are my results with the following commands:
Hope that helps.

Vecherka
I’m pretty sure that there is a console command to disable the filtering. All forms of AA have been disabled using commands.
If you want to get the effect I have, use “r.screenpercentage 10” and “sg.AntiAliasingQuality 0”
Does this affect only the G buffer rendering to viewport or does it also affect HUD layer? I want to get this kind of low res rasterization on the Camera without it affecting the HUD
This worked great. Thanks!
Hello mightyenigma,
the spatial upscale pass does proceed the user interface pass, so it won’t affect any screen space UI elements.
Okay so it does not affect the UI sounds like. Good
