I have this issue, when my door opens it kinda glitches through the wall, and make some kind of blurry trail…
I tried with other materials, with only texture to base, and nothing more, but the issue still persist.
I also disabled motion blur in the project settings, and tried changing the bound scale, but nothing helped…
I’m pretty lost to be honest, and tried googling a lot, but couldn’t find anything…
In the video you’ll see, that when I’m close enough it goes away, but as soon as the camera goes further away, it starts again.
I thing you are searching for Anti-Aliasing. You can change the scalability level
You can find a lot of details about these things, in the official documentation here:
