I’ve been using UE5 for a few months now and I’ve noticed this issue since day one. At first I thought it was just an editor optimization or something but it seems to just get worse the more detailed my project gets.
Essentially, there is this odd warping of textures or distortion when the camera moves. I’ve tried using all different Anti Aliasing methods, and I’ve completely disabled Motion Blur, none of which made a difference.
It’s a bit hard to see in an empty scene but I wanted to illustrate that I can reproduce this by simply creating a new level, dropping the Third Person Character BP in and running. (You can see it best around the leg area here).
Does anyone know what this is? When I first noticed this, it looked more like a weird pixellation/white fuzziness around the edges of geometry as the camera panned around them, but now it looks more like stretching.
Interesting, I turned off Lumen and it certainly does remove the stretching artifacts. However this puts me back at the first issue I noticed where it’s sort of pixelated/white on the edges of geometry as I turn the camera. Is this all GI related? (I’ve got it set to None at the moment). Bit worrying as GI is a bit of a must have for my current project.
Not sure what the white edges are related to there, but the previous problem was Lumen. You basically can’t have a lot of sudden movements, because it can’t keep up.
You might try the various anti-alias methods to see if it fixes this one…
those are most likely motion vector artefacts. temporal stability is not there. the movement is too harsh. you clobber the algorithm. hence why it “breaks”.
