I got 3 dynamic point lights, one near the glass on the left, the second near the table and the last one in front of the elevator doors.

These point lights helped me to get a nice dynamic specular that I can’t have with the baked one on the objects.

I put the major spot baked lights near the doors, It was hard at the beginning to have the same look, and approximately the same intensity, bounce and other light settings for the same feel as the photo, the main difficulty was to keep some zone dark and other bright without moving the spot or adding one because this can make a big difference comparing with the main reference.

Unity’s Advancements

Since the 5.4 Unity added the “Denoising” for the final gather which smartly reduces any noise produced by the static lights. I always use it when I do my final bake, take care when you activate the Final gather it costs more time to calculate.
