I tried so many ways to fix the noise (white lines) between the floor and the wall but it is always there and I am new to unreal engine what should I do?
welcome to the community.
looks like ambient occlusion.
if it looks noisy it’s because of how the gi and ambient occlusion works. you can try changing it on the project settings.
thank you for replying, it only appears when I press the play button and what is GI stands for?
GI = global illumination; real-time, volumetric lighting vs pre-computed (baked) lighting.
You would likely refer to it as ‘dynamic lighting’, which it is, in that it’s calc’d at runtime, but it’s global for all lighting in the scene, not just one light in particular
