I'm currently experiencing an issue I can't find an answer to anywhere, It seems like something is casting a shadow in my scene that any lights I place can't overwrite. And the area it covers changes based on where I look at it from. It also effects the lights making them cast light favoured to one side. Here are some example images, I have no clue what's going on.
PS. It's not some invisible object I tried booting up a new blender scene and just used a plane and the issue still showed up.
Edit: Someone asked if I was using a normal map, yes I am. everything was working perfectly for a while then idk when but this lighting just started happening out of nowhere.
