For VR indoor lighting, my method is 120 flat houses, and some windows in the living room corridor are 15 or so, and the lights are reduced downwards on 2, 3, 2 and 3, 15 or 30. There is no need to shoot the lights. Different optical networks have different parameters. Finally, fill the light. Try bit by bit from 5.

VR rendering material can have a standard rote memorization, but lighting is not. This needs to be tested.

It will be helpful to see more photo-level rendering.

Observe the changes of light and shadow in life.

The materials should be matched, otherwise the lighting will be no good.
