1 00:00:00,000 --> 00:00:01,680 Our particles are using 2 00:00:01,680 --> 00:00:04,310 the same texture that we have for the ground floor. 3 00:00:04,305 --> 00:00:05,585 That means it's going to be using 4 00:00:05,580 --> 00:00:06,600 the dirt texture and 5 00:00:06,600 --> 00:00:07,980 that's not going to look good at all. 6 00:00:07,980 --> 00:00:09,690 It's going to look like dead grass. 7 00:00:09,690 --> 00:00:11,460 So let's create a new material 8 00:00:11,460 --> 00:00:13,520 so the grass actually is green. 9 00:00:13,515 --> 00:00:15,695 We're gonna do this by coming over to the top 10 00:00:15,690 --> 00:00:17,580 right and splitting this view and 11 00:00:17,580 --> 00:00:20,010 switching it over to the shader editor 12 00:00:20,010 --> 00:00:21,840 over in the material tab, 13 00:00:21,840 --> 00:00:23,040 we're going to hit that plus 14 00:00:23,040 --> 00:00:24,770 sign to create a new material. 15 00:00:24,765 --> 00:00:26,255 Then click on New. 16 00:00:26,250 --> 00:00:28,700 And remember, we're going to need to name our materials. 17 00:00:28,695 --> 00:00:31,065 So we're going to call this one grass. 18 00:00:31,060 --> 00:00:32,780 I'm going to press N to close up 19 00:00:32,780 --> 00:00:34,810 that panel because we don't really need it. 20 00:00:34,805 --> 00:00:38,035 So the first node that I'm going to add is a hair info. 21 00:00:38,030 --> 00:00:39,500 Note, if we press Shift a, 22 00:00:39,500 --> 00:00:42,410 we can go underneath input and then add in the hair info. 23 00:00:42,410 --> 00:00:46,450 Node B is intercept option is the one that we want. 24 00:00:46,445 --> 00:00:48,565 This, this allows us to set where 25 00:00:48,560 --> 00:00:50,990 the color is on the bottom and the top. 26 00:00:50,990 --> 00:00:52,850 We can do this with a color ramp. 27 00:00:52,850 --> 00:00:54,370 So press Shift a and add in 28 00:00:54,365 --> 00:00:57,335 a converter colorRamp and place it here. 29 00:00:57,335 --> 00:01:00,455 We'll take the intercept and plug it into the factor 30 00:01:00,455 --> 00:01:01,615 than the color into 31 00:01:01,610 --> 00:01:04,360 the base color of the principled shader. 32 00:01:04,355 --> 00:01:07,345 To see what we're doing, we can open up the preview. 33 00:01:07,340 --> 00:01:09,620 And instead of using the circle, 34 00:01:09,620 --> 00:01:12,790 we're going to use the strands right here. 35 00:01:12,785 --> 00:01:14,795 As you can see, this is actually working. 36 00:01:14,795 --> 00:01:15,865 It starts out dark on 37 00:01:15,860 --> 00:01:18,190 the bottom and then it becomes white. 38 00:01:18,185 --> 00:01:20,095 So now what we're gonna do is hit that 39 00:01:20,090 --> 00:01:22,310 plus sign to add in a new handle. 40 00:01:22,310 --> 00:01:25,360 And this handle is going to be a nicer green color. 41 00:01:25,355 --> 00:01:28,615 So bring it over to a green and drag it down. 42 00:01:28,610 --> 00:01:31,040 Then we're going to hit that plus sign one more time. 43 00:01:31,040 --> 00:01:32,960 And this time we're going to bring it over here. 44 00:01:32,960 --> 00:01:36,520 And I'm going to switch this one over to a lighter green. 45 00:01:36,515 --> 00:01:38,485 And I think I might drag this one actually to 46 00:01:38,480 --> 00:01:41,800 a darker green, something like that. 47 00:01:41,795 --> 00:01:43,825 And drag it this way. 48 00:01:43,820 --> 00:01:45,980 I'm also leaving a little bit of white at 49 00:01:45,980 --> 00:01:47,240 the very top because that is 50 00:01:47,240 --> 00:01:48,580 what actual grass looks like. 51 00:01:48,575 --> 00:01:49,765 There's a little bit of white at 52 00:01:49,760 --> 00:01:51,800 the very top of the grass. 53 00:01:51,800 --> 00:01:53,630 The next thing that we're going to add is 54 00:01:53,630 --> 00:01:55,430 a little bit of translucency. 55 00:01:55,430 --> 00:01:57,910 This will allow light to pass through the grass. 56 00:01:57,905 --> 00:02:00,395 Because if you take a look at grants one more time, 57 00:02:00,395 --> 00:02:01,885 you can see there is a little bit 58 00:02:01,880 --> 00:02:03,550 of light that can go through it. 59 00:02:03,545 --> 00:02:05,945 To add this in, we're going to press Shift a and add an, 60 00:02:05,945 --> 00:02:08,785 a shader and then a mix shader and place it here. 61 00:02:08,780 --> 00:02:10,580 We're then going to press Shift a and add 62 00:02:10,580 --> 00:02:12,920 in a translucent shader. 63 00:02:12,920 --> 00:02:16,420 We're gonna take the BSD f and plug it into the shader. 64 00:02:16,415 --> 00:02:18,305 And then you can see here in the preview 65 00:02:18,305 --> 00:02:20,215 that light is actually passing through it. 66 00:02:20,210 --> 00:02:21,860 Now, you can control 67 00:02:21,860 --> 00:02:24,760 how much light is by setting the factor value. 68 00:02:24,755 --> 00:02:29,045 We're going to set this a little bit lower, 2.25 n Enter. 69 00:02:29,045 --> 00:02:30,545 And then for the color, 70 00:02:30,545 --> 00:02:33,755 we're going to drag it down just slightly. 71 00:02:33,790 --> 00:02:35,630 And there we go. 72 00:02:35,630 --> 00:02:37,820 That is our result. 73 00:02:37,820 --> 00:02:40,040 To actually see this in action, 74 00:02:40,040 --> 00:02:42,080 we're going to drag this window out a little 75 00:02:42,080 --> 00:02:46,440 bit and then press Z and go into rendered view. 76 00:02:46,930 --> 00:02:49,370 At the moment you won't see anything. 77 00:02:49,370 --> 00:02:51,440 And that's because we need to actually assign 78 00:02:51,440 --> 00:02:53,750 those particles do have that material. 79 00:02:53,750 --> 00:02:55,130 And to do that, we can go over 80 00:02:55,130 --> 00:02:56,990 to the particle system tab, 81 00:02:56,990 --> 00:02:59,840 scroll down until we see the render panel. 82 00:02:59,840 --> 00:03:00,620 You can see them. 83 00:03:00,620 --> 00:03:02,540 It's current material is set to dirt and 84 00:03:02,540 --> 00:03:04,820 we need to set it over two graphs. 85 00:03:04,820 --> 00:03:06,350 So switch it over to grass. 86 00:03:06,350 --> 00:03:08,710 And then there is the effect that we have. 87 00:03:08,705 --> 00:03:11,515 I'm going to press Control B and box selected 88 00:03:11,510 --> 00:03:13,310 just a small portion of the grass and then 89 00:03:13,310 --> 00:03:15,910 zoom in on it to see what it looks like. 90 00:03:15,905 --> 00:03:17,755 We also have a problem over 91 00:03:17,750 --> 00:03:19,430 here about some of the particles 92 00:03:19,430 --> 00:03:22,550 are actually going through the ground right here. 93 00:03:22,550 --> 00:03:24,470 And the reason that's happened is because 94 00:03:24,470 --> 00:03:26,680 we extended the walkway. 95 00:03:26,675 --> 00:03:28,495 So let's go ahead and fix that by going into 96 00:03:28,490 --> 00:03:31,400 edit mode and just selecting that part. 97 00:03:31,400 --> 00:03:33,140 So I'll just click on those vertices. 98 00:03:33,140 --> 00:03:36,400 I'll press C for circle select and draw a box around. 99 00:03:36,395 --> 00:03:39,575 All of those will go along the back here, 100 00:03:39,575 --> 00:03:42,355 then press X and just delete them. 101 00:03:42,350 --> 00:03:43,960 Now if we go out of edit mode, 102 00:03:43,955 --> 00:03:46,165 that should fix the issue. 103 00:03:46,160 --> 00:03:47,450 There we go. 104 00:03:47,450 --> 00:03:49,670 So now if we go back into camera view Z 105 00:03:49,670 --> 00:03:51,080 and go into rendered view, 106 00:03:51,080 --> 00:03:52,850 there are no particles peeking 107 00:03:52,850 --> 00:03:55,280 through and that looks pretty good. 108 00:03:55,280 --> 00:03:57,410 Let's take a look at the entire thing 109 00:03:57,410 --> 00:03:58,520 by closing this window, 110 00:03:58,520 --> 00:04:00,640 by clicking in the top right, closing that. 111 00:04:00,635 --> 00:04:02,455 And then press Control B and draw 112 00:04:02,450 --> 00:04:04,840 box outside the camera view. 113 00:04:04,835 --> 00:04:06,955 And there we go, Look at that. 114 00:04:06,950 --> 00:04:08,510 We now have grass in our scene 115 00:04:08,510 --> 00:04:10,610 in and is looking pretty good. 116 00:04:10,610 --> 00:04:12,680 The reason you can't really see a lot of 117 00:04:12,680 --> 00:04:15,040 the strands is because of the de-noising. 118 00:04:15,035 --> 00:04:16,705 Once we do a final render is 119 00:04:16,700 --> 00:04:18,470 going to look a lot better because we're going 120 00:04:18,470 --> 00:04:20,180 to add more samples and 121 00:04:20,180 --> 00:04:21,590 the shadows and everything and 122 00:04:21,590 --> 00:04:23,090 some other render settings. 123 00:04:23,090 --> 00:04:25,480 We will cover all that in a later video. 124 00:04:25,475 --> 00:04:28,375 For now though, we've completed this section. 125 00:04:28,370 --> 00:04:31,310 The next section after this is the final section 126 00:04:31,310 --> 00:04:32,690 where we're actually going to be jumping 127 00:04:32,690 --> 00:04:34,010 into the Render Settings, 128 00:04:34,010 --> 00:04:35,210 learning how to render in 129 00:04:35,210 --> 00:04:38,490 cycles and making it look really good.
