High resolution screenshot has bad reflections

Hi unreal guys.
I am doing some archvis, which is working pretty ■■■■ good in ue4.
my screensize is 1920 x 1200 pixels if i take a screenshot from the maximized view [f11] i got the same result as on my screen.
if i use the high resolution screenshot tool, i am getting very noise and jagged reflections and some artifacts that shouldnt be there at all.
i really would love to get higher resolution screenshots with the same quality than the viewport.

is this a known issue [if, will it be fixed ?]
are there other ways [ a new monitor with higher resolution , etc. ] to get clean reflections in high resolution screenshots ?

kind regards

Hi guys, no help here ?

High-resolution screenshot doesn’t work with the temporal AA that UE4 uses. Reflections in UE4 look a lot worse without temporal AA. Therefore, a high resolution screenshot is going to have bad looking screen-space reflections unless you take it at an extremely high resolution. The easiest way to get a better quality screenshot in this case (to the best of my knowledge) is to just set the game resolution very high and take a normal screenshot.

thx for the answer !
will this be adressed in the future [otherwise i see no benefit of the high resolution screenshot-tool.
Can i run unreal engine in a higher resolution than my monitor is capabal off ?
is there a windowed mode ?
my monitor at this time only supports 1920x 1200 pixel, which is not enough for serious archviz …

kind regards

Yes. There are two ways. When you have the game running, execute the console command:

r.ScreenPercentage 200

And your game will run internally at 200% resolution, which works as a supersampling antialiasing technique. Obviously your framerate will be terrible, especially if you turn it up even higher than 200% :slight_smile:

You can also run the game in windowed mode, and then execute:

r.SetRes 2560x1440

or whatever resolution you want. You can combine those for higher quality, if your GPU can handle the frame buffer.

By the way, if the answer above helped you, mark it as answered/resolved so that it shows up for other people if they search for the same question. Thanks!

thx for helping.
this only works while game is running ?
could i use something in the editor for doing highres screenshots ?
in editor i can switch through cameras easily and make corrections to cameras etc. so i would really like to take the screenshots there.
