Let there be.......

Continuing to look at how a scene can be developed, I have just the one source here, a central atria, which illuminates the central kitchen/laundry area.

The light is from a HDRI painted onto a 'surface' under the atria dome.

Have you thought about making the under surface of the artistic an emitter?

I have tried this numerous times in the past, it is never worth it. Directing the HDRI is a much more effective solution do far.

Does TwiLight support high dynamic range emission from geometry? HDRIs need to be global lighting to flood scene. Maybe I'm reading your text wrong?

It's a good idea to test the lighting using a clay render first. Just to see what needs to be changed to 'bring' more light into the scene.

Two types of sky portal, one where you see the hdri image and a second which just directs the light values for the hdri minus the image.

I sometimes use clay as you describe, it depends on how the mood takes me. Right now my pain levels are on the high side so I tend more to the experimental side and this series is adding one elements at a time a little bit more extreme than I usually do. I have a LOT of time to kill.
