I will explain from second part:injacphi wrote:What do you mean when you say:
Power in Area Light, for example Power 2.0, or for LEM light.
Sun Power I suggest leave 3.0 - it gives more warm in room.
how do you change that light setup?
- Sun Photons need to be a bit stronger the usually it means when photons from Sun hit dark floor you lose power of photons
here without Power: here with Power 5: You can add Power for all sources of light. But I suggest use maximum value 3.0 no more.
For Area Lights/LEM in windows better is to keep default 1.0 but if you have difficulty to bright up interiors you can use Power for all lights.
btw. in this example I turned OFF all lights except Sun Light (to vivid effect)
And here all lights ON:
- Sphere GI outside (actually it gives not so much photons but this is for reflection effect)
- Area Lights in Windows (default)
- Sun Light with Power 3.0
This system is used everywhere. Only what is missing: good surfacing
One more render: beautiful spectrum of interpolated photons
