Light from windows too bright, how to turn down?


Does anyone know why the light coming in to this room from the windows is “off the charts” dazzling, whilst the light in the room itself is so dark?

I want to evenly light up the room, I’ve switched off the eye adaptation by setting min max fps camera autoexposure to 1.0, there is also a light source directional light with an intensity of 1.0?

Please help!
