Why is their weird noise in my render lighing and why does my lighitng still look off? I followed the tutorial here by Ducky3D, and it turned out I needed to scale down my scene a lot as light keeps flickering every time I move around my scene and the final result still doesn't look that good.
Also when I rendered the image, there was weird noise around my scene because of my lighting.
It could be the default shadow settings for Eevee.  Try setting the cube size higher in this menu.
