1 00:00:06,000 --> 00:00:12,130 All right now let's take a look at lighting our scene and the different options that we have for lighting 2 00:00:12,130 --> 00:00:13,430 our scene. 3 00:00:13,680 --> 00:00:18,310 Now we already went over the emitter but we're going to go over that a little bit more. 4 00:00:18,490 --> 00:00:28,000 So first things first let's actually go to the rendered mode so we can see how it looks in real time. 5 00:00:28,000 --> 00:00:32,950 And you can see the armiger object is one way to light up a scene. 6 00:00:33,070 --> 00:00:34,250 We're going to leave this for now. 7 00:00:34,270 --> 00:00:39,710 And let's start with the very basics of how to light the seams. 8 00:00:39,740 --> 00:00:51,100 Now at the very basic basic way is to hit shift day add mesh and add a lamp points lamp over here. 9 00:00:51,290 --> 00:00:56,650 I'm going to hit Z to go back into solid mode and you could see that this right here is our point lamp. 10 00:00:56,850 --> 00:01:02,760 And over here if we go to the options panel you can see that we have the different options for this 11 00:01:02,760 --> 00:01:04,450 point lamp that we have here. 12 00:01:04,530 --> 00:01:08,010 We could obviously change what kind of lamp it is as well. 13 00:01:08,010 --> 00:01:14,190 So instead of hitting shift day add lamp sunspot Hemmy or area you could change it here if you want 14 00:01:14,190 --> 00:01:15,400 to do so. 15 00:01:15,660 --> 00:01:17,990 Right here we have the name of the lamp. 16 00:01:18,030 --> 00:01:25,260 We have some custom custom properties and here's a little preview of the light and how strong it is 17 00:01:25,260 --> 00:01:26,740 or how dark it is. 18 00:01:26,940 --> 00:01:33,140 And it gives you kind of a rough preview or draft of how it's going to look like. 19 00:01:33,500 --> 00:01:35,030 Now right here are your main options. 20 00:01:35,030 --> 00:01:39,250 Again you could choose which kind of lamp you want you can choose the size. 21 00:01:39,260 --> 00:01:44,380 So let's go ahead and actually see what this does in our scene. 22 00:01:44,380 --> 00:01:46,810 It's got to rendered. 23 00:01:47,030 --> 00:01:50,650 And you can see that right now we grab our lamp. 24 00:01:51,510 --> 00:01:53,700 Let's actually split the viewport right here. 25 00:01:55,760 --> 00:01:57,110 And you can see the our lamp. 26 00:01:57,110 --> 00:01:58,390 We have it selected. 27 00:01:58,580 --> 00:02:04,830 And if we increase the strength of it it will actually add more light or less light. 28 00:02:04,930 --> 00:02:09,190 And for some reason actually right now it's not working. 29 00:02:09,190 --> 00:02:18,620 So there seems to be a glitch with it when you go ahead and delete it hit shift day add lamp points. 30 00:02:18,780 --> 00:02:20,010 And there we go. 31 00:02:20,160 --> 00:02:24,990 Not to sure what was happening with that one I might have touched a button by accident but I don't believe 32 00:02:24,990 --> 00:02:25,590 so. 33 00:02:25,830 --> 00:02:31,920 So right here again you could change the strength so that it's stronger. 34 00:02:32,190 --> 00:02:34,480 You see right here it's getting brighter and brighter. 35 00:02:34,570 --> 00:02:35,300 If we put it. 36 00:02:35,300 --> 00:02:40,610 Crank it up to a thousand and see that's very very bright. 37 00:02:40,620 --> 00:02:45,330 And again the strength determines the brightness of the light. 38 00:02:45,600 --> 00:02:50,960 Now of course the color as the name implies changes the color of the lighting. 39 00:02:51,420 --> 00:02:54,330 And right here we have the size. 40 00:02:54,510 --> 00:03:01,840 Now the size is basically for the shadows in order to see this putter. 41 00:03:01,840 --> 00:03:04,080 Let's go ahead and add a plane in. 42 00:03:04,120 --> 00:03:09,340 So shift day and mesh plane we're going to add a ground floor. 43 00:03:09,340 --> 00:03:16,300 So scale this up over your whole scene and hit GZ and bring it down under your house. 44 00:03:19,460 --> 00:03:23,780 Like so make sure it's under the house 45 00:03:28,280 --> 00:03:29,460 like so. 46 00:03:29,510 --> 00:03:31,120 So now we have a floor on there. 47 00:03:31,130 --> 00:03:37,700 And if I go back to my lamp by selecting it right mouse clicking I can see that the size is basically 48 00:03:37,700 --> 00:03:45,460 for the shadow sampling which means how many how detailed those shadows will be. 49 00:03:45,460 --> 00:03:54,490 So if we go to shadow over here for example this one if I put the size to point 1 I believe it actually 50 00:03:54,730 --> 00:03:57,550 makes it so that more diffused the less you put it. 51 00:03:57,550 --> 00:04:01,210 So if I put 0 you can see that's a very very sharp. 52 00:04:01,570 --> 00:04:09,600 If I put three I can see that it makes it diffused or it kind of makes the shadow not so sharp. 53 00:04:09,600 --> 00:04:17,170 It it it bounces it more across the objects and makes it so that it's not a straight black line which 54 00:04:17,170 --> 00:04:19,060 is for the most part shadows. 55 00:04:19,060 --> 00:04:26,050 If you look at them the closer you are for example if you project your hand your shadow on a wall the 56 00:04:26,050 --> 00:04:30,430 closer you hand is to the light the more precise the shadow will be. 57 00:04:30,520 --> 00:04:36,550 But the further away your hand is from the lights it will start to diffuse just like this. 58 00:04:36,550 --> 00:04:37,890 So again zero. 59 00:04:38,080 --> 00:04:42,440 It's completely you know completely straight line of a shadow. 60 00:04:42,580 --> 00:04:49,840 And the more you increase this the more it will diffuse across the plane or whatever the shadow is falling 61 00:04:49,840 --> 00:04:50,470 upon. 62 00:04:50,470 --> 00:04:57,130 So I'm going to leave it at one and then right here the bounces is basically the number of light bounces 63 00:04:57,130 --> 00:04:59,280 that are occurring in the render. 64 00:04:59,410 --> 00:05:08,180 If I put this to zero you can see that it has a certain particular effect and if I put this to 3000 65 00:05:10,260 --> 00:05:12,740 You can see that it changes it slightly. 66 00:05:12,750 --> 00:05:17,420 Now again the max bounces actually only goes to 1024. 67 00:05:17,460 --> 00:05:19,100 So you can see them at 3000. 68 00:05:19,230 --> 00:05:26,880 But for the most part I just leave it at the default of 1024 and the size again the size you want to 69 00:05:26,880 --> 00:05:34,080 play around with because 0 is usually unrealistic and you kind of want to add a little bit of fuzziness 70 00:05:34,080 --> 00:05:35,050 to your shadow. 71 00:05:36,220 --> 00:05:40,740 Now the surface light that we have here is emission it's an emission lamp. 72 00:05:40,780 --> 00:05:44,660 And again we went over the color and the strength already. 73 00:05:44,680 --> 00:05:45,920 Now this is a point lamp. 74 00:05:45,940 --> 00:05:54,130 It would be great for something such as a lamp a bedside table a lamp in the street you know as the 75 00:05:54,130 --> 00:06:02,920 name implies it just emits from this little particular spot and it emits from there and shoots out. 76 00:06:02,920 --> 00:06:05,780 Now the sun lamp is drastically different. 77 00:06:05,830 --> 00:06:11,890 Let's put the brightness way down on the sun lamp let's put it to 100 maybe even that's too much let's 78 00:06:11,890 --> 00:06:18,700 put it to turn or one maybe was put it to three. 79 00:06:18,910 --> 00:06:27,610 So the Sunland as you can see it doesn't really have a point of origin that it goes from a kind of no 80 00:06:27,610 --> 00:06:31,480 matter how far the light is for example with the point. 81 00:06:31,480 --> 00:06:35,790 The closer it is the more it illuminates. 82 00:06:35,810 --> 00:06:39,150 You can see right there on the floor if it's right next to Flora will illuminate the floor. 83 00:06:39,170 --> 00:06:45,890 And the further away the more the light dissipates the sun lamp doesn't agree to any of those rules 84 00:06:45,890 --> 00:06:49,350 or terms a sun lamp just goes on pretty much forever. 85 00:06:49,460 --> 00:06:57,310 Doesn't matter really where you place it in the scene now does matter how it's rotated or position. 86 00:06:57,500 --> 00:07:04,280 You can see that if I rotate it like so right now I'm hitting our wants to rotate and then our once 87 00:07:04,280 --> 00:07:11,960 again to tumble it could see that if I place it like this we can get pretty cool shadow of our house 88 00:07:12,470 --> 00:07:13,760 like so. 89 00:07:14,180 --> 00:07:20,890 So it does cast a shadow but the lighting as far as the distance doesn't really get applied. 90 00:07:21,140 --> 00:07:22,890 Now again the size. 91 00:07:23,420 --> 00:07:27,380 So once again the sharpness of the shadow 0 is very sharp. 92 00:07:27,380 --> 00:07:28,760 You can see it has a pretty cool feel. 93 00:07:28,760 --> 00:07:32,130 I mean you can have a cartoon that has these kinds of shadows. 94 00:07:32,390 --> 00:07:38,570 And the higher you go the more diffused the shadow will be on the floor. 95 00:07:38,570 --> 00:07:43,580 Again we have the max bounces and we can select if it casts a shadow at all or not. 96 00:07:43,580 --> 00:07:47,290 And this one right here like the name implies. 97 00:07:47,300 --> 00:07:53,750 I've actually never used this one quite honestly but apparently reduces noise for area laughs and sharp 98 00:07:53,750 --> 00:07:55,140 glossy materials. 99 00:07:55,190 --> 00:07:57,060 So that would be on an aerial lamp. 100 00:07:57,200 --> 00:08:04,130 And if you have glossy materials the noise the noise if you don't know is all these little pixels when 101 00:08:04,130 --> 00:08:10,070 you move all the little dots and pixels those are the noise that's the noise of the image. 102 00:08:10,130 --> 00:08:15,560 As you can see right here sampling is at 10 11 12 13. 103 00:08:15,620 --> 00:08:20,140 The higher it goes the less noise or the less grainy it will be. 104 00:08:20,300 --> 00:08:26,350 So this basically as an air implies it reduces the noise for area lamps and sharp glossy materials. 105 00:08:26,600 --> 00:08:34,460 So as regarding to this lamp I don't believe it does much as it's four area lamps and shiny materials. 106 00:08:34,460 --> 00:08:36,140 Now again we have our color. 107 00:08:36,200 --> 00:08:41,530 We can change our color that affects the sun lamp for sure and the strength. 108 00:08:41,740 --> 00:08:44,620 The next light is the spotlight. 109 00:08:44,660 --> 00:08:46,150 This one is pretty cool. 110 00:08:46,160 --> 00:08:48,430 This is kind of like the sun lamp. 111 00:08:48,720 --> 00:08:51,900 And the point lamp mixed together. 112 00:08:52,130 --> 00:09:00,770 So I'm going to hit Allt are to clear the Loek the rotation and bring it down here and move it up as 113 00:09:00,770 --> 00:09:01,640 well. 114 00:09:01,640 --> 00:09:12,140 Now I'm going to increase the strength to 50 and you will see that if I bring this up more increase 115 00:09:12,140 --> 00:09:13,610 the strength even more 116 00:09:16,600 --> 00:09:23,720 you will see that for some reason is not actually shining. 117 00:09:23,720 --> 00:09:27,870 I'm curious to know why. 118 00:09:27,970 --> 00:09:29,200 There we go. 119 00:09:29,590 --> 00:09:33,220 Let me change the color of it and make it a little bit harder to see. 120 00:09:35,130 --> 00:09:39,880 All right so if I increase the strength even more you can start to see right here. 121 00:09:40,110 --> 00:09:46,200 We have a big spot on the floor and actually if we turn down the size we'll see it even better because 122 00:09:46,590 --> 00:09:48,650 it's going to be sharper on the edges. 123 00:09:48,960 --> 00:09:53,850 And let's increase the strength to 2000. 124 00:09:53,850 --> 00:10:00,420 And now you can see that the spot lamp is basically as the name implies it. 125 00:10:00,750 --> 00:10:08,100 It's kind of like you would probably use this and you know those scenes with the actors and you know 126 00:10:08,100 --> 00:10:14,730 behind the scenes or the the rock and roll concert you know spotlights or a street light. 127 00:10:14,740 --> 00:10:19,770 You could use this as a street light as well it's very useful for that because it creates this spot 128 00:10:19,770 --> 00:10:21,420 lamp on the floor. 129 00:10:21,420 --> 00:10:29,060 Again the size is the the the diffuse or the Nonda fuse of the shadow you could see a higher number 130 00:10:29,070 --> 00:10:31,970 it's very diffuse and at zero. 131 00:10:32,040 --> 00:10:35,130 It's very clear crisp and clear. 132 00:10:35,190 --> 00:10:43,080 You could also put Show Coan which will show you the cone right here of how the light where the light 133 00:10:43,170 --> 00:10:48,750 is within the scene so you can see if you have objects within this light there are going to be lit up 134 00:10:49,110 --> 00:10:53,390 from this lamp or this spotlight. 135 00:10:53,610 --> 00:10:55,380 Also you could change the size of it. 136 00:10:55,380 --> 00:10:57,870 This is the angle of the spotlight. 137 00:10:57,870 --> 00:11:05,800 So by changing it you're actually making a thinner or thicker or bigger and then the blend right here. 138 00:11:05,880 --> 00:11:12,540 This is basically as the name implies it softens the spotlight edge which kind of does the same thing 139 00:11:12,750 --> 00:11:14,540 as the size up there. 140 00:11:14,700 --> 00:11:20,580 But we have an extra option here and you could see you could even get an even crisper feel to it. 141 00:11:20,760 --> 00:11:26,190 And this is dictated by this second circle within the circle here. 142 00:11:26,190 --> 00:11:34,830 So the further in the second circle the more diffused it is the further out or closer to this main circle 143 00:11:35,100 --> 00:11:38,460 the more it's going to be crisp and sharp. 144 00:11:38,460 --> 00:11:41,040 So that's pretty much the spotlight. 145 00:11:41,040 --> 00:11:42,830 It's really awesome light to use. 146 00:11:42,930 --> 00:11:46,880 And of course you can change the color of it as any other lamp.
