How to get physical correct results

Hi Guys,

I am trying to achieve a correct and realistic image as much as possible.
Could you please explain me a relationship between different settings and elements of Maxwell?

Here is a list of things that a bit confusing.

1. I use HDRI for exterior render and for my lights inside the building use real world parameters.
To make more realistic result should I keep real values for Lights, make exposure for this lights and then adjust HDR multiplayer?

2. If I am using Maxwell Sun/Sky system and ies lights , should I do the same thing? Keep my camera exposure for the lights and then adjust Sun/Sky intensity?

Is it correct? Or you are using different approach?

3. And one more thing. Is it possible to get clouds on Maxwell Physical Sky?

Thanks

1. You should stay tied to the real emitter values and crank up/down the IBL intensity as needed.

2. As they are all physically correct, they should match without adjustment. If you still find one or another weaker or stronger then feel free to adjust any of them.

3. Physical sky doesn't have a cloud generator. You could try volumetrics...
