Can’t you use two different Post-Process Volumes with the respective EV settings? It’s a little more work, since we can’t assign actual EV values like in the viewport, but all the proper settings are there to match what EV is based on.
For simplicity, since I don’t think it has any effect other than offsetting the necessary shutter speed/f-stop right now, you can just leave it at the default ISO of 100. For instance, EV16 at ISO 100 would require f/16 and a shutter speed of 1/100 or 1/125.
Edit: If you want automatic exposure, I’m a big fan of the change to the Basic method where it automatically adjusts for a particular gray(default is 16%, cameras typically go for 12% to 18%). If you use physical values for your lights, you’ll need to increase the Max Range to around 10,000. You could also enable Pre-Exposure to improve the quality of the exposure adjustment and fix any artifacts from the high values, but that will break the reading in the Pixel Inspector. Any other adjustments needed for particular areas can be done with the exposure compensation per Post-Process Volume.
We have approximately 80 houses within just 1x1 Km area, we can’t really use one PPV per house for correcting the interior exposure. Other issue with that method is that if I want to make a change to interior PPV, for the sake of consistency I’d have to do it for every other PPV as well (and our actual game world contains hundreds of interiors).
