    Best soft lighting for housing x-sections?

    I'm hoping for an easy/quickish rendering solution for lighting a home with the roof and several levels pulled apart.

    DPs infinite light looks good and gives nice soft shadows, as does the DP dome (albeit slower to render) - but both of these start to break down when you have a roof and/or tall walls casting too many shadows. I can play games with making some layers not cast shadows, or have their own lights and other lights excluded....

    I would love to just have a simple solution that more or less light everything with softish shadow occlusion in the corners, and doesn't care much about the "reality" of shadows blocking hidden corners from seeing much light.

    Thoughts?

    Are you rendering items as separate pieces or that's just how the object is constructed? If separate, you might just want to set up a "Limbo" environment light using a Grad. Posting a shot never hurts.

    I do a lot of sets and even though they won't contribute much for many interiors, I always start with a good general HDR. That'll get windows, skylights, etc. & some flooring. Radiosity won't carry all that far but gives a good overall feel for time of day.

    Inside, I'll then lay in Area lights, which is probably what your after. I mostly use them as work lights using the various room ceilings from a Top view as a guide. Create the light but then immediately Rotate it -90 on P, then scale & position. Raise it up to be near the ceiling, above any hanging lamps, etc. I turn off normalize & set to 1 lx typically. Area lights are single sided so if you need to see the ceiling too, just dupe that one, flip to +90 P, then parent in Place to the first.

    With that base lighting in place, I then can see where start putting in motivated lighting like table lamps, overheads, sconces, etc.

    It's changed a lot since this, and is still changing.

    I'm not really looking for mood lighting, just quick to render, easy to setup soft-ish light everywhere...

    Thanks, that looks about right, though I'm still not sure it's gonna get inside things and lite up the interior? Guess I wont know as I am running an older version of LW. Any other ideas folks?

    For versions prior to LW2018 without the Environment light, maybe just bump up the Ambient Light?
