When a new 2D Animation file was created, I noticed that unlike general workspace, the whole background looks bright white. Meanwhile, there was no light source in collection. The way I understand it is that essentially, we need light source while rendering, or we won't see jack. Yet in 2D animation, the world is lit without an obvious light source in the collection, and I can render my animation without worrying about light problems.
I wanna know what makes 2D animation special? Was it some sort of settings that I don't know about?
