1 00:00:04,220 --> 00:00:05,360 ‫Hello and welcome. 2 00:00:05,360 --> 00:00:11,930 ‫In this lecture, we're going to be making the inside of our dungeon completely pitch black by adding 3 00:00:11,930 --> 00:00:18,380 ‫some panels around the outside to essentially block out any light from bleeding in to the dungeon. 4 00:00:18,380 --> 00:00:23,390 ‫This is a preparatory step for the next one, which is going to be to actually light the dungeon. 5 00:00:23,390 --> 00:00:26,120 ‫So let's dive in and see how this works. 6 00:00:26,510 --> 00:00:32,390 ‫So when we were playing around with lighting in the last level, you may have seen that we instantly 7 00:00:32,390 --> 00:00:39,290 ‫got some updates to the lighting and if we brought in objects, we could instantly see the effects of 8 00:00:39,290 --> 00:00:39,890 ‫those lights. 9 00:00:39,890 --> 00:00:42,440 ‫And there's lots of scattered and soft bounce lighting. 10 00:00:42,530 --> 00:00:46,910 ‫And this is due to a new development in Unreal five called Lumen. 11 00:00:46,910 --> 00:00:53,900 ‫It's a real time global illumination light engine and because it's fairly new, there are still some 12 00:00:54,080 --> 00:00:59,930 ‫features that are not supported in Lumen and you can see this going on with this material on the wall. 13 00:00:59,960 --> 00:01:03,020 ‫You can see how it's kind of got this weird shadowing effect. 14 00:01:03,020 --> 00:01:08,750 ‫Well, this is because there are some features being used in its material that are not supported yet 15 00:01:08,750 --> 00:01:09,350 ‫by Lumen. 16 00:01:09,350 --> 00:01:15,950 ‫So what we need to do is we need to edit this material and we can find the material for this particular 17 00:01:15,950 --> 00:01:16,700 ‫segment. 18 00:01:16,700 --> 00:01:18,830 ‫Like, so click on the wall. 19 00:01:18,830 --> 00:01:22,610 ‫Let's go down to the area where it says materials. 20 00:01:23,330 --> 00:01:28,640 ‫And under the materials you can see we've got this stone wall insert. 21 00:01:29,240 --> 00:01:35,150 ‫If we select that in the content browser and we scroll down to the stone wall what it means by insert, 22 00:01:35,150 --> 00:01:38,270 ‫what does it mean by having that underscore insert at the end? 23 00:01:38,270 --> 00:01:42,140 ‫Basically what it's saying is this is not actually the material itself. 24 00:01:42,140 --> 00:01:44,060 ‫It doesn't tell it how to render the material. 25 00:01:44,060 --> 00:01:51,500 ‫It's just essentially like a blueprint of the material that tells it which textures to use and other 26 00:01:51,500 --> 00:01:52,250 ‫settings. 27 00:01:52,250 --> 00:01:57,860 ‫So what we need to do is right click on it and click Find Parent. 28 00:01:57,860 --> 00:02:00,710 ‫And if we click Find Parent, then open the content draw again. 29 00:02:00,710 --> 00:02:04,010 ‫You can see we've got this m tiling master hovering over. 30 00:02:04,010 --> 00:02:09,860 ‫That does show us that this is indeed a material this is the master material that the other materials 31 00:02:09,860 --> 00:02:10,850 ‫are made from. 32 00:02:10,850 --> 00:02:15,530 ‫So we can click this to open it up and we now get the material. 33 00:02:15,530 --> 00:02:19,250 ‫Editor It's very much like a blueprint editor. 34 00:02:19,250 --> 00:02:22,970 ‫You can see there's all these nodes here except we don't have an execution pin. 35 00:02:23,000 --> 00:02:24,710 ‫These are all just data pins. 36 00:02:24,740 --> 00:02:27,950 ‫It doesn't really matter as to how this works. 37 00:02:27,950 --> 00:02:29,150 ‫Exactly. 38 00:02:29,150 --> 00:02:32,930 ‫The important thing is that all the output data is going into this node at the end. 39 00:02:32,930 --> 00:02:38,600 ‫And one of the things that isn't supported in Lumen is this pixel depth offset. 40 00:02:38,600 --> 00:02:44,420 ‫We basically can't use that, so we need to disconnect it and we can do that by clicking on the pin. 41 00:02:44,450 --> 00:02:45,470 ‫It can go away. 42 00:02:45,470 --> 00:02:53,150 ‫Then we go to the toolbar and hit Apply and it's going to go ahead and recompile the material code, 43 00:02:53,150 --> 00:02:56,480 ‫recompile the shaders and have that available in our level. 44 00:02:56,480 --> 00:03:02,060 ‫Now if we go over into the dungeon, you can see that weird shadow effect has gone away and we've got 45 00:03:02,060 --> 00:03:03,560 ‫a better looking level. 46 00:03:03,560 --> 00:03:07,040 ‫So now it's time to start lighting the interior of our level. 47 00:03:07,040 --> 00:03:13,250 ‫You can see there's a lot of light bleeding in to this interior of the level and that is because actually 48 00:03:13,250 --> 00:03:21,410 ‫our ceiling is a one sided mesh and so light's kind of coming through in to the room and we'd see this 49 00:03:21,410 --> 00:03:27,260 ‫even more if we do the following, because Lumen is a real time system. 50 00:03:27,290 --> 00:03:31,400 ‫It really works best when we use real time lights. 51 00:03:31,400 --> 00:03:32,660 ‫And what do I mean by that? 52 00:03:32,660 --> 00:03:38,990 ‫Well, if we go to our global folder and select the directional light and have a look in the details 53 00:03:38,990 --> 00:03:46,190 ‫pane, you can see that there is a mobility setting here and this basically tells Unreal whether we 54 00:03:46,190 --> 00:03:50,750 ‫intend to move or modify this object when the game is playing. 55 00:03:50,750 --> 00:03:57,050 ‫So static means know nothing is going to change about this object full stop and that allows unreal to 56 00:03:57,050 --> 00:04:01,100 ‫bake in a lot of things like lighting settings before you play the game. 57 00:04:01,100 --> 00:04:06,740 ‫There's stationary which says you can't move it, but you can change things like the brightness and 58 00:04:06,740 --> 00:04:09,620 ‫then there's movable, which basically means anything could change. 59 00:04:09,860 --> 00:04:16,310 ‫Now, funnily enough, Lumen, the new unreal lighting system works best when your lights are set to 60 00:04:16,310 --> 00:04:17,120 ‫be movable. 61 00:04:17,120 --> 00:04:22,460 ‫So if we switch our directional light to movable, you can instantly see the problem here that essentially 62 00:04:22,460 --> 00:04:27,830 ‫the light is just coming straight through the ceiling panels because from the lights point of view, 63 00:04:27,830 --> 00:04:30,020 ‫they aren't there, they are one sided. 64 00:04:30,020 --> 00:04:36,050 ‫And so it doesn't actually create any shadow in here and we can do the same thing, sets the other light 65 00:04:36,050 --> 00:04:38,750 ‫in our scene to move ball, which is the skylight. 66 00:04:38,750 --> 00:04:41,870 ‫And that's just going to compute all of our lights in real time. 67 00:04:41,910 --> 00:04:45,170 ‫That's much easier to deal with lighting. 68 00:04:45,170 --> 00:04:47,990 ‫When we're doing everything in real time, we're using lumen. 69 00:04:47,990 --> 00:04:52,520 ‫So let's start having a look at how we can block out the light here. 70 00:04:52,520 --> 00:04:58,700 ‫I think one of the easiest ways to do this is actually just to take the floor meshes and lift them up 71 00:04:58,700 --> 00:05:02,270 ‫to be a roof over the top of our dungeon. 72 00:05:02,270 --> 00:05:03,200 ‫That's certainly one way we. 73 00:05:03,330 --> 00:05:03,820 ‫Into it. 74 00:05:03,830 --> 00:05:11,240 ‫So I'm going to go ahead and search the outline of the floor and then look in the dungeon folder and 75 00:05:11,240 --> 00:05:13,510 ‫just select the dungeon floor elements. 76 00:05:13,520 --> 00:05:23,660 ‫Then I'm going to go to the four pane view and I'm going to pull the floor up while clicking to duplicate 77 00:05:23,660 --> 00:05:28,010 ‫it and bring it up to a level where it can be as ceiling. 78 00:05:28,010 --> 00:05:34,880 ‫Here, if we go inside, I just want to check that it is indeed blocking out the light effectively and 79 00:05:34,880 --> 00:05:36,110 ‫it seems like it is. 80 00:05:36,110 --> 00:05:41,120 ‫If you bring it too close, then you can get some light bleeding in. 81 00:05:41,270 --> 00:05:44,930 ‫So we don't want it to close, but we do want it just close enough. 82 00:05:44,930 --> 00:05:50,840 ‫Like so perhaps so they would go and knock out any light bleeding into this room except from these corners. 83 00:05:50,840 --> 00:05:55,820 ‫And if you pop out, you can see why the edges are not quite meeting the top here. 84 00:05:55,850 --> 00:06:02,090 ‫So what we need to do there is put some of that edging meshes around there. 85 00:06:02,090 --> 00:06:06,740 ‫So if we look for Edge in our medieval dungeon, we've got the edge stones. 86 00:06:06,740 --> 00:06:15,110 ‫Let's drag those in and place them next to these objects and duplicate it along. 87 00:06:15,140 --> 00:06:22,400 ‫Maybe changing the grid, snap setting to be one meter and we'll duplicate and duplicate again. 88 00:06:22,790 --> 00:06:27,200 ‫And we've got ourselves hopefully the light being blocked inside our dungeon. 89 00:06:27,200 --> 00:06:27,500 ‫Yep. 90 00:06:27,510 --> 00:06:30,170 ‫Looks like it's being blocked quite effectively. 91 00:06:30,170 --> 00:06:36,350 ‫And just for completeness sake, I'm going to take these three edge stones, select them and duplicate 92 00:06:36,350 --> 00:06:44,720 ‫them over to the other side like so, and then rotate them 90 degrees with a duplicate and then duplicate 93 00:06:44,720 --> 00:06:46,820 ‫it on over here as well. 94 00:06:46,820 --> 00:06:48,350 ‫So you can see that inside. 95 00:06:48,350 --> 00:06:51,050 ‫Now we've got a very, very dark dungeon. 96 00:06:51,050 --> 00:06:54,830 ‫And if you wanted to check that, we can indeed illuminate it at all. 97 00:06:54,830 --> 00:07:02,390 ‫Then we could just go to our quickly add go to lights and drag in a point light to see the effect of 98 00:07:02,390 --> 00:07:03,950 ‫illuminating the dungeon. 99 00:07:03,950 --> 00:07:06,620 ‫So I'd like to challenge you to block out the light. 100 00:07:06,620 --> 00:07:08,240 ‫So you've seen how I've been doing it. 101 00:07:08,240 --> 00:07:12,140 ‫Add floor and edge stones around the whole of your corridors. 102 00:07:12,140 --> 00:07:18,770 ‫You may need to rotate them so that you can cover some of the rounded areas, for example, around that 103 00:07:18,770 --> 00:07:19,610 ‫mausoleum. 104 00:07:19,700 --> 00:07:24,260 ‫And you might also want to check that all your corridors are dark once you've finished and there's no 105 00:07:24,260 --> 00:07:28,880 ‫light bleeding in from any places, you need to cover them all up, make it all dark. 106 00:07:28,880 --> 00:07:35,420 ‫So pause the video and have a go and remember that you can use the unlit mode to move around when things 107 00:07:35,420 --> 00:07:36,080 ‫are dark. 108 00:07:36,080 --> 00:07:37,610 ‫So pause a video and have a go. 109 00:07:40,770 --> 00:07:40,980 ‫Okay. 110 00:07:41,070 --> 00:07:41,770 ‫Welcome back. 111 00:07:41,790 --> 00:07:46,610 ‫So let's remove this light from our scene because we don't need it. 112 00:07:46,620 --> 00:07:49,800 ‫We just want to see whether we're making everything nice and dark. 113 00:07:49,920 --> 00:07:54,720 ‫So what I'm noticing here is we've got the edge stone here that we don't really need because the edge 114 00:07:54,720 --> 00:07:57,390 ‫is actually over here at the end of the staircase. 115 00:07:57,390 --> 00:07:58,740 ‫It's a bit of a funny shape. 116 00:07:58,830 --> 00:08:03,830 ‫So let's go ahead and move that edge along. 117 00:08:03,840 --> 00:08:10,770 ‫Then I'm going to copy a couple of edge stones from the already built section and duplicate them to 118 00:08:10,770 --> 00:08:17,490 ‫the other side of this corridor and select a couple of floor panels and move those along to. 119 00:08:17,520 --> 00:08:22,470 ‫Now, switching into unlit mode, let's go and position ourselves so we can see the staircase. 120 00:08:22,470 --> 00:08:28,260 ‫Then switch back to lit and you can see that the staircase is looking pretty dark in here. 121 00:08:28,260 --> 00:08:32,880 ‫We just need to cover up the crypt area now. 122 00:08:32,880 --> 00:08:36,090 ‫So we're going to select all of that crypt flooring. 123 00:08:36,090 --> 00:08:40,860 ‫So I'm doing that by searching the outline of a crypt floor and then selecting all of it. 124 00:08:40,890 --> 00:08:46,890 ‫And I think I just need to be careful to deselect these two bits of floor at the start of the staircase. 125 00:08:46,890 --> 00:08:51,360 ‫And it looks like there's this crypt floor wall trim to deselect as well. 126 00:08:51,390 --> 00:08:58,320 ‫Then when I'm confident it's all at the same level, I'm going to alt and drag it up to make a duplicate. 127 00:08:58,350 --> 00:09:05,490 ‫Looks like I may need to change the grid snapping b 50 because of the height of the ceiling. 128 00:09:05,520 --> 00:09:07,500 ‫Then I can bring it up one level more. 129 00:09:07,530 --> 00:09:13,560 ‫Now if I switch to unlit mode, I can position myself inside the corridor to have a little look go to 130 00:09:13,560 --> 00:09:17,460 ‫lit and I can see that it's starting to look quite dark. 131 00:09:17,460 --> 00:09:24,690 ‫These architraves have got a bit of light bleeding, so I think I just need to position them a probably 132 00:09:24,690 --> 00:09:30,030 ‫ten centimetres higher altogether so there's not any light bleeding from those architraves and then 133 00:09:30,030 --> 00:09:33,390 ‫any of the edge that doesn't quite match up here. 134 00:09:33,750 --> 00:09:38,130 ‫We're going to have to put some edging stone around that. 135 00:09:38,130 --> 00:09:45,780 ‫So let me just go and check that we've got a little bit of an issue here where light's being let in 136 00:09:45,780 --> 00:09:52,710 ‫from the back side of this decorative wall and also from the back side of these mausoleum meshes. 137 00:09:52,710 --> 00:10:01,470 ‫So let's try and fix that by duplicating some roof and maybe rotating it down to cover this piece that 138 00:10:01,470 --> 00:10:03,300 ‫was bleeding light. 139 00:10:03,300 --> 00:10:08,400 ‫And if we want to be safe and have some margin for error, we could actually copy two of them across 140 00:10:08,400 --> 00:10:12,120 ‫here so that there is absolutely no way light's coming in there. 141 00:10:12,120 --> 00:10:17,040 ‫And we probably want to do roughly about the same thing with our mausoleum. 142 00:10:17,040 --> 00:10:24,900 ‫Duplicate some wall down here, rotate it about 90 degrees, and then I'm actually going to duplicate 143 00:10:24,900 --> 00:10:27,660 ‫it to be higher as well. 144 00:10:27,660 --> 00:10:33,960 ‫And the flooring does need to be higher up on the mausoleum to let the whole roof fit. 145 00:10:33,960 --> 00:10:40,110 ‫And I think these walls need to be a smidge further out to not include some of this mesh. 146 00:10:40,160 --> 00:10:45,450 ‫Looks like we've still got some light coming in from somewhere, so I'm just going to duplicate a couple 147 00:10:45,450 --> 00:10:47,940 ‫more panels like so. 148 00:10:47,940 --> 00:10:54,330 ‫And along the top to switch to unlit, let's go inside the mausoleum and have a little look around back 149 00:10:54,330 --> 00:10:55,140 ‫to lit. 150 00:10:55,140 --> 00:10:55,560 ‫Okay. 151 00:10:55,560 --> 00:10:58,110 ‫Looks like it's just the edging stones to do now. 152 00:10:58,110 --> 00:11:02,610 ‫Or actually because this area is not going to be visible from the exterior, it doesn't matter how it 153 00:11:02,610 --> 00:11:03,030 ‫looks. 154 00:11:03,030 --> 00:11:09,120 ‫So we can just add some extra flooring like this and just make it extra wide. 155 00:11:09,160 --> 00:11:12,480 ‫Then inside you can see that there's no bleeding going on. 156 00:11:12,480 --> 00:11:18,930 ‫So we can do that same procedure with the rest of the corridor, move some of it slightly across, and 157 00:11:18,930 --> 00:11:22,460 ‫then the rest over to the right switch to unlit check. 158 00:11:22,470 --> 00:11:29,310 ‫I'm inside the corridor and then back to lit and everywhere, apart from that door is looking completely 159 00:11:29,310 --> 00:11:30,120 ‫pitch black. 160 00:11:30,120 --> 00:11:31,230 ‫Is that true? 161 00:11:31,260 --> 00:11:34,110 ‫Even when I'm looking up the staircase, I wonder. 162 00:11:34,110 --> 00:11:36,450 ‫Let's have a look at the staircase. 163 00:11:37,170 --> 00:11:38,670 ‫Hit lit. 164 00:11:39,390 --> 00:11:39,670 ‫Yeah. 165 00:11:39,690 --> 00:11:41,550 ‫It's looking pretty dark in here. 166 00:11:41,550 --> 00:11:42,990 ‫Very, very dark indeed. 167 00:11:42,990 --> 00:11:43,620 ‫So there we go. 168 00:11:43,620 --> 00:11:50,160 ‫We've effectively blocked out any light bleed that we were getting inside our dungeon, which will set 169 00:11:50,160 --> 00:11:54,240 ‫the stage for lighting it properly in the next video. 170 00:11:54,240 --> 00:11:55,080 ‫I'll see you there.
