It has two modes

• Day mode
• Night Mode

The bedroom scene contains 104 objects. In the bedroom scene there are multiple cameras with different angles as shown above. In the daylight mode fake indirect lightning is used to get faster renders, bright and less noisier image. If you want to remove fake indirect lightning you can remove it but you have to increase scene exposure and suffer with longer render times and noisier image.

In night mode there is a emission material on tube light (which is on by default) and point light on lamp (which is disabled by default). If you want to turn of tube light just change it's material to no light

Fake Indirect Lightning

In fake indirect lightning area lights are placed on the projection of the sunlight on wall, objects etc with the color of their projection this gives effect of indirect lightning, brightens the scene, reduce noise and faster render time
