Scene full of noise :-(

Hello, I have a question why when rendering a scene full of noise

    It's a largely enclosed space - if you are lighting it with the default HDR or other "external" lights (distant lights, Sun and Sky, HDRs) then it relies on light paths bouncing their way in through the openings - of which there appear to be few. The same applies to using a limited number of local lights. In general, for a nose-free render, you want as much of the scene as possible tor eceive direct light from a source - you can then use the Tone Mapping properties in the Editor tab of Render Settings to adjust the final look.

    Recommend me some lighting solution.  The headlight is not ideal.  Any invisible light panel on the ceiling?

    There is the ghost lights product (although I recently heard you could also turn a spotlight into a meshlight) to add some ambient lighting here and there. In movie making sometimes they also use extra lights that aren't really there in the scene.

    According to the blurb in the shop it has lighting settings.

    • Lights off
    • Lights on blue
    • Lights on white
    • Lights on yellow

    Yes it has lights, but they don't work very well

    In what way? You may have to change the Tone Mapping settings to get more light. Depending on the lights you can also try changing the Lumen settings for them.

    I lowered the iso to 50, set the aperture to about 3, and did exposure compensation.  Render takes 6 hours and still quite a lot of noise.  I render to 8000x4000 px and then I shrink

    May I also recommend running your finished render through blender's built in denoiser? I've recently begun using it over the one Daz includes,it works amazingly well and takes less time to do it's job over the one Daz uses.

    Looking at the Promo images I would say all those white lights along the ceiling are Emissive surfaces, which is the same as mesh lights although I have never used the product, and they can be changed in the Surface Tab to increase the light setting.

    Here the result after turning on all the lights in the materials and the whole ceiling I put Ghost light. I attach thumbnails from the settings
