Thanks for looking at this. I have HD 2024 so dont have the exposure settings. It's strange using dusk sunlight it doesn't accurately let light in through the windows. It automatically overlights the room when you enter, and you can see the light is dramatically brighter than outside (magical lighting). I have turned off the automatic light settings and added a lamp to override but it still automatically lights up the room, and seems no way to override this to use natural outside sunlight. It seems it's designed to be on or off in some generic way, designed first and foremost for best illustrative lighting conditions but not realism.
The best way I have found to get close to the lighting conditions of my real life house is to use street lights outside but this is giving strange light paths across the floor not through windows.
