If you don't have a Directional Light created in the scene, you can go to Create -> Lights -> Directional Light. This is and the lighting which is this directional light and skylight I have currently in my scene and the last thing is the camera we have and the post process. Okay, so the directional light that we have, I'm going to click on this so I can see the details that I can change for it. And the first thing I want to do when I do the lighting is adjust these shadows, so how the shadows are. And when you click on the directional light, you can select the rotate tool and you can try to rotate the sun to get interesting shadows. So for example, for example, this is cool and try to adjust it this way too. This is pretty cool, maybe a bit less like this. I want to use these shadows. The next thing is, you can see these shadows are very dark. We don't want these two dark shadows, it's not looking realistic or good, we want them to be softer. So before we do this, let's add a sky here. And the sky you don't find here because it's a blueprint. And the way you find it is if you go into the settings here to the right and click on show engine content. And inside of the engine content, try to search for sky and you find the BP sky sphere. This one you can drag into the level and you can see you now have a sky. So this sky I am going to place inside of my lighting folder and in the details panel you can change the Sun height so it's not a sunset but the Sun is up all the way. So now we have a sky to look at like this. You can try to play with the Sunlight, see what you like for your scene, if you want sunset or not. But I'm going to leave it like this for now. And the next thing is we want to adjust the shadows. So inside of the skylight, you can increase the intensity of the skylight. You can see here, if I increase the intensity to 2 the shadows become a lot more soft and if I put back to 1 it will go back to the very dark shadows. Okay so now it has calculated the shadows and this is because we have now added a sky so now it knows that it's not fully dark. So before we adjust the lighting to there's a small trick and it is let me find it inside of lights and if you press this small arrow here you will see something called lower hemisphere and this is actually the lower part of the models. Right now it's set to dark so for example if I put the color to red you can see that the lower part of the models become red I put it to blue they become blue they become green and so on so this is very important because we want this guy to reflect correct colors onto the models so right now we actually want this sand color to be reflected because the sun is coming down casting the light and we want this this color to be cast on the models. So we want this color and the way we do it just like before, click on lit and in the buffer visualization go to base color and now you can click on the color picker for the lower hemisphere on the skylight and you can choose this light brown sand color. So now we can go back to the lit mode and it's actually casting the correct sand color. I'm going to press File and Save All. Now let's go back to the skylight and let's adjust the shadows until we are satisfied. So if we put it to 0.5 it goes back to like before. If we put it to 2 maybe this is 2 light shadows or maybe this is fine. So this is all about trying out and seeing what's working for your scene and what doesn't. I think this is too dark. So maybe 1.5 is cool for the scene. Actually, let me go to the camera actor and pilot this. And from this I can go back to the highlight and try to see what it looks like. Okay, I think 1.2 is fine for my scene. So if I maximize it you can see now we can actually see what's beneath these shadows and they are not too dark. So this is looking great for now and we can always adjust it later on. And actually before I light more things I want to go inside of my post process and I want to disable some things so I can view the image more clear so inside of the post process image effects I want to go into the vignette and write zero because now I'm viewing the scene without the vignette if you have the vignette enabled you might mess up with your lighting because this is going to make it darker. So make the vignette zero. You can also go down to... let's find the bloom up here and make the bloom zero too. And let's see if we have other things we can turn off. Translucency. We have some ambient occlusion we can play with later. And I think this is fine. So and and we can change the light direction This is like a sun with a lot of clouds on a cloudy day. And let's see. Maybe this is what we're going for, like a more cold color. So now this is with the sun fully up. And I actually like the more coldish style. So let me like with the more more more clouds on the sky so Reducing the color. Okay, so I think I'll go with the intensity to one. So this is a more more sky within like with a lot of clouds or a bit of a colder sky So the sky box doesn't fit too well because it would be better if there were sky Very good. I think it's called... I don't remember what it's called actually, but if you search for sky that you can view all of the different skies in there. And let me see if we can change some settings to make it look better. Actually cloud opacity 0.7 was fine. Yeah, there isn't a... There isn't a parameter we can change to increase the amount of clouds, but this is a very basic sky right from the engine. What I would do, I would go inside of the marketplace. I have a very good one that I use and it is also the highest rated one in the marketplace. You can take a look at it. You'll probably find it easily, but this is fine for now. This is good. This will do and this is looking good so far. So what we can do now now we have the Directional light and we have the skylight and this is actually it for the outside lighting Because you don't really need a point light. This is for indoors and we don't have a spotlight or rec light So this is this is looking fine so far what we can do to make it a bit more interesting is we can add some fog. So if you go inside of here, you can either find the fog or you can try to search for it. I think you can, yeah, if you write fog, you can search for it. And let's add a exponential height fog. So drag it into the scene. And you can see we have added it into the scene so in here you can click on the fog and you can change the fog density and you can also change the falloff of the fog and you can change the start distance of the fog and the cutoff distance so I'm trying to change the fog density try try to change it to 0.5. You can see it's very large or you can change it back to 0.1. So right now I'm just trying to adjust the fog and seeing like making a more interesting look from my scene. Okay, I think the 0.1 would be very good for me and you can adjust the opacity if you want, you can adjust the falloffoff you want. I think this is looking fine so far. So you can also change the color if you want to change it a little bit. I'm going to change it just a little so it's not too blue just like this maybe and you can toggle off and on the fog to see what it looks like with and without. So I'm going to maximize my scene and I take a look at it. Looking fine so far. And what you can do now is you can go inside of the direction of light and you can change the temperature if you want. If you want a more warm beach or if you want a colder scene. And actually I'm going to remove this because I want to edit this inside of the post process But I think I'll go with a more cold look of the scene because this is war and something happened Let's go back to the post process Okay, so inside of the post process I want to change the color so down here in the white balance. I'm going to tick these I'm going to decrease it to give the scene a more colder look. So maybe 6000. See this is before and this is with it. So very subtle change and you can add a tint for a more red color. So just slightly, so 0.02. So it tints the scene a little bit and maybe it goes to 0.01. Just like that. Okay, so you can also play with the saturation. So if you think this is too desaturated, you can increase the saturation. I think 1.2 This is looking more interesting and you can always play with the contrast with the gamma and the gain And I think I think this is cool so the gamma we want to stay on the same and the gain We can stay on the same too you can always change the offset too but I think this is looking fine so far and what we want to do now is inside of the bloom I can change the intensity of the bloom to give it a more dreamish look or something like this and obviously if you're playing this is for a game you don't really want to put bloom people hate bloom You can always add an option in the settings to turn on and off the bloom But I think this is too much Let me see what the other default value is 0.6 But not much is happening 0.8 I think this is a good value and the last thing is the vignette. So I want to turn it up again to make a more interesting scene. So 0.4 is the default. Okay, so this is our scene so far. It's looking more interesting than previously where it was fully dark. And I think you can increase the sun just slightly the intensity. Now it's looking a little bit too dark. So inside the intensity maybe 1.5 or 1.2 and we can go back to this full screen. Okay so this is looking pretty cool so far. I think we can go to the next lesson and we will add the blood decals on the sandbags and we will also try to add some wind on the grass so we give more life to the scene.",
