I am trying to make a plain white room in Unity. I used six planes for the walls, but I can't figure out how to get the lighting to not look so harsh and uneven. The top picture is my best attempt using two directional lights, and the bottom picture is the look that I am trying to replicate. It is from a demo scene in the Google VR SDK 1.50 for Unity. It uses only a single point light, but when I turn it off in the scene view, it doesn't change the appearance of the room at all. How can I make my room look more like the Google VR demo?
EDIT: I made a big improvement by changing all my walls to be static so that they receive indirect lighting, and adding a single point light above the roof.
