Hello! I’m trying to use UE5.7 for the first time and i see wierd lines everywhere, no idea why
Default light setup (they exist on None, Lumen and Screen space). Anyone has ever seen those or is it me just been blind and ue always had it?
They look pretty harmless until i try adding cel shading (green thing - cel shaded, defaul grid - usual shading, barely can see them)
Hello there @KonguKordan!
No, you not crazy, I can see it too. That looks like shadow acne, or a similar artifact glitch. What’s surprising is the fact that it shows up even in default maps/settings.
Considering that last part, we need to check your system’s status first. I would suggest a clean up of your current GPU drivers install, using DDU. After that, get the latest from your provided and install from scratch. If you are on nVidia, I recommend the Studio drivers, those are the most stable for engine work.
After that, the other out of engine test would forcing UE to open with a different DirectX. Use the -dx11 tag in your shortcut to force it on DX11, and check if the artifacts still appear. Now, engine wise, please test the following adjustments:
Open any map, and go to Project Settings > Engine > General Settings, look for “Near Clip Plane”. The default value should be at 5, play around with a few increases (10, 20, 40), and check if the artifacts dissapear.
You should also change your current shadow method. By default, UE starts with Virtual Shadow Maps, so go to Project Settings > Engine > Rendering, and switch it to classic Shadow Maps
Finally, you can test by fully disabling AA, by running console command “r.AntiAliasingMethod 0”
Hope these help, and good luck!
