Lighting not changing

Hi team, I'm using an environment set called Snug Living Room by Goriav and no matter what I do with the lights I've added, the render is always the same. Changing light values does nothing, even turning them off altogether until the viewport is black! I have the environment set to scene only and the camera lights off. I thought maybe there is a built in lighting system on the set but nothing in the tree to show lights or adjustment of. Any ideas?

Thanks

    Here's what I mean, pic attached. As you can see no lights on, viewport black but when rendering it's bright.

    There are probably a lot of emissive surfaces - surfaces with a non-black Emission colour.

    It looks from the shadows on the shelves that the lighting is above so have you switched off the emissives on the embedded ceiling lights?

    EDIT: I don't have the product but the file list shows:

    • /Props/Goriav/Snug Living Room/Room/Materials/SLR Ceiling LEDs OFF.duf

    That item should switch them all off for you.

    I do have that set. Yes, and theya re quite bright - the table lamp is set to 6,000W, most of the other surfaces are 6,000 cd/cm^2. The Tone Mapping is default, which is suitable for a bright day outside - any realistic local lights you add will most likely be swamped. I would suggest radically dialing the emission values down and adjusting the Tone mapping to soemthing suitaable for a well-lit room, then add your own lights (and if desired zero the emissive surfaces entirely).

    Thanks guys. Turning the ceiling lights off didn't make any difference so I'm guessing it's the other things.

    Excuse my ignorance but I'm not sure what you mean by the emission values or how I adjust them, the emission colours on the surfaces are all black. As for the tone mapping in render settings, well, there's rather a lot of dials there, where do I start? Presumably it's exposure and shutter speed?

    Thanks again

    Apologies guys, it was the ceiling lights causing the issue. I thought I had turned them off but I hadn't. I only discovered this after a lot of faffing about but at least I got there.

    Thanks for the advice

    Select the surface of a luight emitter, then the emission settings are in the Editor ab of the Surfaces pane.

    Yes, just use the Exposure setting unless you know camera settings and prefer to use those.
