Somehow ended up with this shot, lit by just a few spotlights. I`m now re-rendering one with sunlight falling in as well.

Last one, lit by 7 IES lights..rendered overnight in about 9 hours on 2x GTX1060
A lot of noise still, I think I have a few random glass objects that`s causing it.

And letting one render out after 13 hours overnight with daylight, straight out of the viewport:

Cooked after 11 hours till 10000s/px, changed the overall look, lights and floor. Floor is a mix-material with
OSL
This might be interesting, I re-rendered the same scene but without the very glossy standing lamps and table lamps turned on, and the rendertimes went down to about 45 minutes instead of 11 hours..
I did adjust adaptive sampling when difficult areas were cleaning up, but still, big difference

Changed the shape of emitters (left image -> table and standing lamps) from actual high poly bulb shape to simple low poly plane emitters and the rendertime decreased drastically to 4 hours instead of around 11. .IES lights and sampling rate to 10k.

Finally got to test out my new 3080, it`s blazing fast and makes iterating on lighting so much faster. For the HDRI of the scene I used the ACES 2065-1 colorspace option instead of *Linear + srgb*. This overrides the gamma option. Not sure if that`s correct, but the lighting is superb. I`m on OR 2021.1 XB1. Some 16-bit colour correction in Photoshop.
- Does anyone know what White spectrum to use? For this render I used D65 with *old pipeline*, but I don`t really see much difference as I build up the scene from scratch.
- The file is used is an .orbx from the 3dsmax plug-in in Standalone, and I noticed that the camera is skewed. Is that common?

Thanks elska! Funny I always just set SR to 10k, but tweaking might help.
I did notice some colour difference in the passes. I think I read somewhere that`s a bug, but not sure.
The main pass differs in colour from the denoised pass.
