    Thanks for all the support, guys!

    About the suggestions/questions:

    CharlestonS: I agree. I don't like plain textures for the grass, they are always going to kill the realism except for some special situations (very far from camera, right angle, etc...). I think using geometry for grass is always the best option for realism, even for the short grass. That's what I'm trying to use now. But thanks for the suggestion, I'll take a look at your libraries!

    viscorbel: Totally agree with you about the cartoonish look of the grass.. UE4 doesn't have special shaders for vegetation, so we need to play a little with the tools. That tall grass is an asset I was playing with to study grass creation, it doesn't have good textures for diffuse and normal, that is the reason for the plain look. I'm working on it though. I'll try the scale suggestion on that floor. Thanks

    cadviz: That wall is around 8 inches. The strange thin sensation on that image is because of the window frame, it's thin and it's hiding the outside edges of the wall. It's strange, I agree haha. The lighting settings are simple, just a lightsource and a skylight. For the post processing, I'm using a custom LUT I've made in Photoshop as instructed here: https://docs.unrealengine.com/latest...ing/index.html

    I'm attaching some parameters, hope it helps

          Thanks for your time & sharing your lighting settings...

          Before I try them; I have 2 questions through what I see in your posted images...
          01. In the outdoor images there were some clouds in the (background) sky... does this has any relation with the skylight you used...!!? OR it was a mesh (textured sphere)..?
          02. Did you use the same settings for the indoor production images?
          ------
          The new Grass pushed your production for more awesome reality
          BTW; I found a cool thread talking about creating grass... in case you hadn't see it before

          keep on
          My best wishes

            Great work. If only someone can use this: https://www.youtube.com/watch?v=kLVa0NOFdwM It would be perfect!

              cadviz: 1) Those clouds are generated by the Sky_Sphere. This comes with any template you select when creating a new project. Just play with the "Cloud Opacity" parameter there and you'll be able to get some nice results. 2)Yes, it's everything the same for indoor and outdoor. I've set the lightmass parameters in order to get nice and smooth results indoor. For outdoor that is overkill, you can reduce the quality if you are going to have only outdoor material without visual losses.

              PLASTICA-MAN: I've just seen this right before your post. NVIDIA is doing great things with their GameWorks, first VXGI and now this grass technology. I hope they make those stuff available for a good price...

                New grass, trees, lightning and colors for the first project. It's a 5x res screenshot with no anti aliasing filter.

                For the grass, unfortunately, foliage system doesn't support static shadows and dynamic shadow costs almost 20fps for that lawn. So I'm using all the instances without any kind of shadow (some work on the material to simulate some shadow on the bottom part of the grass). Then, I turn "cast inset shadow" on for the objects that will cast shadow over the grass. It works and costs little, but then I get some strange and totally dark shadows on some regions like on the side of the left wall.

                Another option is to paint some special instances of the grass over the areas that will receive shadow and activate dynamic shadows only for them, but it demands working on different materials for the no-shadow instances in order to match the visuals of the dynamic ones.

                  That grass looks amazing! Is it a painted mesh 'foliage' layer or a material?

                    Thanks!
                    It's painted mesh. I've tried plain textures and the "carpet" technique in order to get the visuals I wanted, with minor performance cost. But I wasn't able to get convincing results... Those meshes costs about 10 or 20 fps, but the scene still keeps more than 50fps, so I think it's an acceptable cost.

                      The new grass is great improvment over the last one, I still do think it's one of the strongest giveaways in an otherwise stunning viz, but it already looks stunning. Keep it up, mate!

                          And I shall not stop following that improvement!!
                          Keep on keeping on...
                          I have one comment (if you don't mind) about the (windows glass material)... In the last image (the sunrise one) I agree to make it transparent, because the indoor lights are stronger than outside one...
                          But (at day time) when the sun comes up, the window glass would be reflective more than transparent (concerning with your camera position); so it acts like a mirror... for that I suggest to change that material for the daylight images..

                          My Best wishes

                              Very nice... Congratulation
                              Are you intent on more improvement !!? I think this is fairly enough to say about UE4 realism

                                Thanks =)

                                I think it's already nice for the original purpose of those levels (part of an interactive project for master's degree in computer engineering). But it's so fun to spend some time trying to improve visuals... I'll keep trying to improve it...
