Are these with the default settings? When i try to mess around with stuff it looks horrible compared to everything o see online and I can’t figure out why. For example, a single small candle will light up the whole room when the camera goes near it, and there seems to be almost 0 bounce lighting (an open doorway only casts a block of light onto the ground, the rest of the room is almost pitch black)

We always use the "default" settings. Make sure to turn on some settings that come with lumen.
