Light is too dark on 3D models

I've already tried. Nothing changes. I think I will never solve this problem

When I make a dark scene I always have this problem with lights and reflection probs. Because they cross the doors and illuminate the next room. Should I use realtime or baked reflection probs? How can I solve these problems? Please help me and if there are tutorials on YouTube send me the links.

To me it seems that there isn't enough light to bounce from outside to all corners of the room. I have a couple of ideas what settings might solve this, but I'm not that good in lighting.

First, try setting the lightmapper to Progressive (ins$$anonymous$$d of Enlighten) - this was introduced sometime around Unity 5.6, and can produce better results than Enlighten. Next, if you have a directional light that serves as the sun/moon, set it at the top into "Sun source" - this might help.
After that, you might try increasing the intensity of the light that comes from outside, although this can create where washed out colors. So you can also try playing with "Indirect intensity" and "Albedo boost" settings.

Note that if you are going for a kinda realistic look, download and add the PostProcessing Stack V2 to your project (it's free). You can get really nice visuals with that, and it also helps if you increase the intensity of your main directional light (with Auto-exposure, Bloom, and Tone mapping effects).

Thanks for answering me. I tried to do everything you told me but it did not have any success. The room remains completely dark. Ambient light does not illuminate the room. I can not understand. I'm trying to add some images but do not let me add them. Please if anyone has another idea, write it down.
