If you could give me some advice why it could be that would be great [ATTACH=CONFIG]38015[/ATTACH][ATTACH=CONFIG]38016[/ATTACH][ATTACH=CONFIG]38018[/ATTACH][ATTACH=CONFIG]38019[/ATTACH][ATTACH=CONFIG]38017[/ATTACH]
    Hihi,

    Do you have a directional lightsource? What is its indirect light intensity? Usually i tweak it to 7-8. LIghtmap resolutions of the walls and ceilings i usually set it to 1024.

      Yeah, I have a directional lightsource. The Lightmap resolution for the floor is 1024, the walls are 512. The inderect lightning intensity is just 1. My biggest problem is that the kitchen furniture appears too dark and I don´t know why. It seams even though I have enough light in the rest of the apartement when I put the furniture inside the whole kitchen appears dark. Any suggestions?

        In the last screenshot I see a lot of shiny stuff, but no reflection capture probe.
        Maybe that would brighten things up a little?

          Here is some of my setup. The Lightmap resolution of the furniture is 256. I hope this helps to solve the problem. Also it is very weird that the light is coming from outside is soo bright at the windows it also looks unnatural Click image for larger version

            What if you just import your assets in the Koola's Lightroom scene and use its setup the way it is? Maybe you'll be able to find out what exactly is causing you trouble experimenting this method.

              I just did that exactly in this scene. I am using his lights, ini,reflection capture, world settings, wall material.... everything. That is why I don´t know what I made wrong

                I can't think of any other potential reason for those light problems that hasn't been pointed out by someone in this thread already... I could dig around the scene and try to find the issue by myself if you want help with that. Just upload the project somewhere and send me the link.

                  the same thing that I thought, upload the scene somewhere and see what others can brings out from it

                    Crank those lightmass settings man! indirect quality = 10, bounces = 100, lighting level scale I use .6 or lower, smoothness .6 or lower. Prepare for long lighting build but it's going to improve quality by a lot. I've tweaked Koola's settings in his demo with those and I got even better results than him!!! and I use default production ini, not the tweaked one by koola (anyway he already stated he used completely random values).

                      Forgive me Futurerave for being so "direct" but, for my opinion, your approach in learning Archvitz lighting/rendering in Unreal is totally wrong (and maybe the metod you use in lighting a scene is wrong too): copying and pasting a whole "structure" of a good project into an empty one, won't let you understand how the things works inside Unreal, and you can't think, even if the project comes out good, to have learnt something; and even conitinue adding lights into a scene when the ones that are already there aren't tuned-up yet, it's a sort of "non sense". So, what are you going to do?
                      Come on Futurerave!, re start all from scratch (without import other-made "structures") and think to one thing at time: Place just one light (directional, sky, spot...) and see how it affects your scene...tweak some parameter (but just one at time) and see what comes out and don't move from that light till it looks ok for your needs, then you can add another light (if needed) and "stay" there till these both works good together...I know that it's a long tedious job, but I think that this is the only way (maybe someone else could suggest a different one)
                      ...you can post here every single step made and the technique adopted for it....it would be lot helpful for us too
                      Cheers,
                      Paolo

                        I tried to do it from sratch but against all the things I read on the websites and forums I could not achieve the same thing. That is why I asked this question in the forum so maybe one of you could help me with to solve the problems. I don´t intend to copy other poeple I just want to understad everythings. As you said earlier it is also hard for you to achieve it so why not help each other. If I will know what was the problem I will gladly share it with you guys.

                        Anyway here is the link for the project. Maybe one of you can look at it and solve the problem:

                              ..I'm downloading your scene, maybe this evening I'll give it a look.

                              Cheers,

                                Found your 1st flaw. Walls are made from brushes and resolution is 512. A brush's lightmap resolution works the other way. The lower the value, the better the lightmap quality wi;l be. Default is 32. Trying with a value of 2. (or try 16, 8, 4, 2)

                                You have over 50 brushes with very high lightmap values. That's most likely your problem :-) Also removed the yellowish tint on some lights!

                                Also, you still had the Koola's scene and yours side by side in the same ''map'', it's going to raise build time for no reason.

                                I'm rebuilding with higher settings and proper lightmap resolution. I'll post results
