I am still testing the OV dome light, your Analytics sound good to me. I just bumped to a new problem when rendering animation.

I do not want to increase the amount of the blue fog in the train interior, since too much is too much. I know this is kind of a k… "So if I raise the camera ISO to 800 and have overall quite normal settings for other camera values as well, then I can have much less intensive lights.
