WEBVTT 00:00.180 --> 00:06.270 And this next series of lessons of this course, we're going to finish out this scene lighting, texturing 00:06.270 --> 00:11.430 and rendering, but basically the dynamics part of this course is pretty much over. 00:12.120 --> 00:19.740 But I wanted to show you how to take this image and scene to a final render, even though we've covered 00:19.740 --> 00:21.240 this in previous lessons. 00:21.510 --> 00:26.550 I wanted to do a little bit of a wrap up here and kind of combine everything we've learned throughout 00:26.550 --> 00:29.300 the course so that we can get a final image that we're proud of. 00:29.670 --> 00:36.600 So to begin with, I wanted to address one little issue I found with Bifrost caching. 00:36.960 --> 00:41.730 When you try to render a scene that doesn't have a cache on it. 00:41.730 --> 00:49.140 So let's say we go to the Bifrost Arrow and originally have already cast it a bit. 00:49.140 --> 00:52.140 But basically this cache started at frame 10 20. 00:52.740 --> 00:57.450 And so all the frames before 2010 20 would give an error. 00:57.900 --> 01:06.270 And so what I had to do was go back into the cache so properties and go back down to the cache. 01:06.540 --> 01:17.700 And I changed this to three, which was replace any encash frames or cache any uncashed frames and leave 01:17.700 --> 01:21.120 any already existing cache frames alone. 01:21.450 --> 01:30.360 So meaning if I played from one zero one, it would cache everything up until we had a cast here at 01:30.360 --> 01:30.950 10 20. 01:31.290 --> 01:37.050 So basically we needed to create a cache here from one to one to 10, 20 to get around this kind of 01:37.050 --> 01:38.280 bug in my ear. 01:38.280 --> 01:44.640 That wouldn't let you render an Arnold without having a cache on every frame. 01:45.240 --> 01:48.600 So we can set this back to one because already cache that out. 01:48.600 --> 01:49.890 But just wanted to talk about that. 01:50.130 --> 01:55.950 In this lesson, we're going to create some grass with the MASH network for the ground playing here. 01:56.280 --> 02:00.960 We can go ahead and hide this because we've already created that ground. 02:01.240 --> 02:02.520 We can hide this as well. 02:02.520 --> 02:10.080 And I do want to use this now as ground inside of the plane. 02:10.320 --> 02:13.620 So I'm going to duplicate it and then hide the original. 02:13.920 --> 02:21.390 So I'm going to say inside ground here and I'm just going to drag this up to the set. 02:21.390 --> 02:26.370 Someone a middle mouse, drag this all the way up to the set to try to keep this a little bit organized. 02:27.930 --> 02:29.730 There's a lot of things in the scene now. 02:29.730 --> 02:31.950 You can see how it gets kind of crazy. 02:33.030 --> 02:35.160 So let's select this. 02:35.190 --> 02:37.920 We're going to hide that one, which is the collider. 02:38.190 --> 02:43.230 So now we can take this inside ground and just kind of scale it down a little bit and basically just 02:43.230 --> 02:46.890 wanted something to be here for. 02:46.890 --> 02:55.080 When the ground gets blown away, like back in here and we can see through, we don't want the grass 02:55.080 --> 02:56.490 normal texture popping up here. 02:56.500 --> 02:57.630 We want something darker. 02:57.990 --> 03:00.780 So that's all that this is going to be used for. 03:01.110 --> 03:05.940 So I'm just going to scale this down so that we don't see the edges of it. 03:06.030 --> 03:10.650 And basically I'm looking at the corners here. 03:11.190 --> 03:13.350 And so now it's scale that we can't see it. 03:13.890 --> 03:18.620 And I'm going to turn on the ground plain here. 03:19.890 --> 03:24.120 So all I need to do is make sure that this inside ground is above that. 03:24.510 --> 03:26.220 So I'm just need to drag this up. 03:28.030 --> 03:38.230 So we could make this kind of more circular here and pull these vertices and this is just so there's 03:38.230 --> 03:45.850 not like hard edges here, but basically, yeah, this is just for. 03:47.410 --> 03:58.960 Kind of visual segue that we don't see the green grass through this once, it's, um, once it is blown 03:58.960 --> 04:04.690 up, so just making something. 04:07.190 --> 04:14.540 You know, reminiscent of ground here or mud or something, so we'll use that here later on. 04:14.870 --> 04:17.080 So for right now, I want to create some grass. 04:17.090 --> 04:26.330 So let's create a plane and we're going to create one blade and we're going to make it be used in every 04:26.690 --> 04:27.730 blade, basically. 04:27.740 --> 04:30.260 So we're going to use Mass to randomize it and whatnot. 04:30.530 --> 04:32.210 So get that to 90. 04:33.350 --> 04:37.320 Let's delete everything below the ground here. 04:37.320 --> 04:43.640 So let's turn on the ground plane so we can see that I'm just going to delete everything that is below 04:43.640 --> 04:47.150 that and I'm going to drag these over to kind of be in the center. 04:48.080 --> 04:50.810 Now, I already have my non-linear binda farmers up. 04:50.810 --> 04:54.650 You can get to those from modeling to form non-linear. 04:54.650 --> 04:59.360 And I just tore that off there because we're gonna use that a couple of times, some to select this 04:59.360 --> 04:59.930 object. 05:00.260 --> 05:06.680 I'm going to go to twist and I'm going to show all so we can see it. 05:07.250 --> 05:16.610 And then I'm going to rotate this up 90 degrees, I guess 180 really, and then I'm going to twist it. 05:16.820 --> 05:21.890 So this is basically just going to give our grass a little bit of a shape here that's not totally flat 05:22.520 --> 05:24.140 and move this over, just a touch. 05:24.140 --> 05:24.950 So it's in the middle. 05:25.310 --> 05:33.770 And then I'm going to select this again and go to bed and I'm going to rotate this up, turn on so I 05:33.770 --> 05:36.380 can see which direction this thing's trying to go in. 05:36.890 --> 05:48.440 So now I can say negative 90 and then just zero those other ones out and drag this to the bottom and. 05:53.140 --> 05:59.450 Turn off, turn the curvature up a little bit here, and it's looking pretty good. 05:59.470 --> 06:02.590 I need to get the bound all the way to the high. 06:02.590 --> 06:06.400 Bounces go further, and then I'm going to turn the curvature down. 06:06.520 --> 06:09.220 Not as far because we're going to have an Masche. 06:09.220 --> 06:18.100 We're going to have we're going to have to have some random rotation so we don't have to worry about 06:18.100 --> 06:18.490 that now. 06:18.760 --> 06:20.860 So I'm just going to scale the top in here. 06:20.860 --> 06:23.560 So it kind of feels like a grass blade. 06:24.220 --> 06:28.570 Maybe expand this one out and take off the. 06:31.810 --> 06:38.170 The soft selection there, so I can have a little more control and I'm just going to scale this whole 06:38.170 --> 06:43.130 thing down, just a touch to be more grass, like a little thinner. 06:43.870 --> 06:45.910 OK, so now we have our piece of grass. 06:46.210 --> 06:50.260 Let's delete the history on it so we can just have it by itself. 06:50.680 --> 06:53.910 And then let's go to the MASH at Under Animation. 06:54.340 --> 06:56.170 It's going to MASH, Create MASH network. 06:56.170 --> 06:57.670 And I want to make sure these are instances. 06:57.670 --> 06:59.020 I don't want a ton of geometry here. 06:59.350 --> 07:01.000 Someone hit applying clothes. 07:01.510 --> 07:06.430 Now it disappears because, you know, hides it by default and you created a massive network. 07:06.430 --> 07:09.930 You can see these blades of grass there. 07:10.720 --> 07:11.080 All right. 07:11.090 --> 07:16.800 So I want to go to the MASH Network and Ashbery, Ed, so I can actually see what's in it and under 07:16.870 --> 07:17.470 distribute. 07:17.470 --> 07:20.950 I want to add this ground as a form of distribution. 07:20.980 --> 07:22.630 So right now it's Liniers in a line. 07:23.020 --> 07:24.880 So want to change this to mesh. 07:25.330 --> 07:28.360 So then it says, give me a message down here, please connect the mesh. 07:28.660 --> 07:33.610 So I need to get to the ground and this middle mouse drag that into input mesh. 07:34.180 --> 07:40.450 So now what we have to do is increase the number of points by quite a bit. 07:41.110 --> 07:46.810 I a couple of zeros here and we can see that the grass is way too small as it is. 07:47.110 --> 07:50.170 So I'm going to grab that original one. 07:50.170 --> 07:54.850 Even though it's hidden, I can still affect it and I'm just going to scale it up so you can see the 07:54.850 --> 07:57.180 grass is starting to get bigger. 07:57.970 --> 07:59.620 So something like that. 08:01.550 --> 08:05.330 Feels kind of right and kind of play with that. 08:06.290 --> 08:12.830 All right, so then now what I want to do is before we get too far, I want to take that visibility 08:12.830 --> 08:21.680 thing and use it to our advantage out of visibility and then grab the render cam as a first drum filtering, 08:21.680 --> 08:23.030 which we've already talked about before. 08:23.330 --> 08:27.710 When I enable that, you'll see the grass get deleted. 08:28.250 --> 08:34.610 Now, we come out of this triangle based on the camera view so that when we increase the number of grass 08:34.610 --> 08:36.680 blades here, it's not going to totally explode. 08:36.680 --> 08:38.480 It is going to get quite a bit slower. 08:39.050 --> 08:45.110 So I'm gonna add another zero there, add another zero and cross my fingers. 08:45.500 --> 08:47.840 It's going to slow down, give me the spinning wheel. 08:48.320 --> 08:54.380 And now you can really see the camera view here and how important that front drum filtering thing is. 08:55.970 --> 08:56.930 So that's looking pretty good. 08:56.940 --> 09:00.530 Now, we just need to kind of vary this up a little bit. 09:00.750 --> 09:01.900 So let's go back to MASH. 09:01.910 --> 09:05.600 Let's go to random at a random node. 09:06.300 --> 09:13.520 It's going to slow down and I'm actually going to go back to distribute and take off a couple of zeros 09:13.520 --> 09:20.270 while we're randomising this so that it's not so slow while we're getting the randomisation stuff going. 09:20.780 --> 09:24.680 So I don't really care about, I mean, I guess position why we can mess with a little bit. 09:25.040 --> 09:29.080 Mainly I want to I want rotation, why I want to spin around. 09:29.090 --> 09:34.220 So now you can see they're all facing different directions and then just give it a little bit and these 09:34.220 --> 09:36.020 other rotation axes. 09:36.320 --> 09:44.840 And then I want to scale in y to be a little bit random, not a ton, just want some different heights 09:44.840 --> 09:45.260 there. 09:45.710 --> 09:49.390 And then I think that's it for that. 09:50.090 --> 09:56.600 So when we bring back up the distribution, add a couple of zeros here, it should look a lot more random 09:56.600 --> 10:00.420 and natural grass there. 10:00.800 --> 10:07.520 So another thing I want to do is let's add a follow up object. 10:07.650 --> 10:15.170 So let's go to the visibility tab here and we'll go to the following object and we'll say create and 10:15.410 --> 10:23.030 take a second and let's jump into the fall off object and nanospheres, OK, let's invert the fall off 10:23.030 --> 10:30.650 so it goes everywhere but the fall of Sfeir and let's create a cube. 10:31.070 --> 10:40.670 And what I'm looking at is to try to keep the grass off of this dirt section of the grave site here. 10:41.330 --> 10:42.710 Some just scale this up. 10:43.550 --> 10:48.110 And again, I think I want to go back to distribute because this is, this is going so slow right now 10:48.530 --> 10:49.220 it's hard to work. 10:49.220 --> 10:55.250 So I'm going to go back here and take a couple of zeros back off so now we can work a little faster 10:56.090 --> 11:07.370 and scale this up and just basically try to cover this grave area so that there's no grass kind of in 11:07.370 --> 11:08.450 this region. 11:08.900 --> 11:11.510 So it makes sense when the 11:14.060 --> 11:20.390 so that it makes sense when the grave busts open, that there's not like fresh grass under all this 11:20.390 --> 11:20.780 dirt. 11:22.530 --> 11:27.950 So I'm just going to increase that interior section so that it's for sure not going to have any grass 11:27.950 --> 11:28.370 in there. 11:28.790 --> 11:36.530 And then when I turn up distribute amount again, and then we should be able to see that this area is 11:36.530 --> 11:37.910 lacking grass here. 11:37.910 --> 11:41.180 So now we can see that is working pretty well. 11:41.670 --> 11:46.340 Might just increase the size of this a little bit again so that it is. 11:47.310 --> 11:48.120 Actually. 11:50.360 --> 11:52.130 Falling off the way I want it to have it. 11:55.870 --> 12:04.600 You know, I just always regret when I turned back up distribute because it's so slow with this many 12:04.600 --> 12:09.500 pieces, even as an instance, or it just gets really bogged down. 12:10.810 --> 12:12.730 So I'm liking where that set. 12:12.730 --> 12:14.350 So I'm going to turn this off for now. 12:14.350 --> 12:20.580 So I'm going to go to a mash mash Ed, and I'm just going to turn this off so that we can do other stuff. 12:20.950 --> 12:23.800 So now we have the grass and I want to create the ground. 12:24.100 --> 12:28.310 So it's texture that I've given you texture to use. 12:28.600 --> 12:31.150 So just click on the ground here and. 12:31.150 --> 12:31.390 Right. 12:31.390 --> 12:34.030 Click and go to assign new material. 12:34.870 --> 12:37.330 Let's use an Arnold standard surface shader. 12:38.050 --> 12:40.710 We'll use the color here. 12:40.720 --> 12:46.920 I'm going to file and then locate the the grass ground here. 12:46.960 --> 12:49.220 We're going to use the diffuse, which just means kind of color. 12:49.870 --> 12:53.410 So now it's six. 12:53.410 --> 12:54.300 It should pop up. 12:54.430 --> 12:58.180 You can see the grass and the scale of this is kind of wrong, right. 12:58.180 --> 12:59.740 Like it's way too big. 13:00.100 --> 13:06.970 So an easy way to deal with that is to go into the go into the file here. 13:06.970 --> 13:09.670 And then you can find a place to de texture node here. 13:09.970 --> 13:16.580 So we can actually just repeat this 10 times in the U and the V to make that a lot smaller. 13:17.230 --> 13:23.080 Now, when we go back into this shader, let's get back to it over here. 13:23.150 --> 13:29.770 The standard, we'll call this grass or we'll call it ground grass. 13:31.510 --> 13:33.820 Now, this also has a normal map. 13:33.820 --> 13:38.650 So let's go to geometry about mapping and hit the little texture thing here. 13:38.650 --> 13:39.760 Add a texture. 13:43.260 --> 13:52.950 And I need to go to file and pull up the normal map, and because we did the 10 by ten thing here, 13:53.220 --> 13:55.110 we need to do that here as well. 13:55.110 --> 13:56.850 So we need to repeat this ten by ten. 13:57.150 --> 14:00.600 So that matches how we did it before. 14:01.380 --> 14:02.420 So that's working. 14:02.880 --> 14:05.500 And then let's go back. 14:06.300 --> 14:12.890 So now we have the ground kind of done and we can look at that through the viewport. 14:12.900 --> 14:15.780 So let's go to Arnold Arnold Reinterview. 14:16.440 --> 14:19.080 And we have one directional light so far. 14:19.080 --> 14:22.200 It's just going to let us kind of see what we've made so far. 14:22.200 --> 14:24.900 We're not really worrying about lighting at this point. 14:26.580 --> 14:28.050 So it's pretty dark. 14:28.950 --> 14:37.170 One thing we could do is crank up the weight a little bit and we can also going to file. 14:37.890 --> 14:41.670 And I just wanted to kind of like a random texture here so that when we have the grass on top of it, 14:41.670 --> 14:45.330 the grass just kind of breaks up this all these little spotty things. 14:45.810 --> 14:53.820 So I'm just going to keep increasing the exposure on this image file until it's something that I like. 14:53.820 --> 14:55.290 I think that's a little too far. 14:56.790 --> 15:05.550 So I think something like that is working, so now we can turn back on the grass from the massive network. 15:06.350 --> 15:13.860 I'm just going to turn this off and then I'm going to I'm just going to save this as a whip just in 15:13.860 --> 15:14.460 case. 15:17.520 --> 15:19.590 And whip means work in progress. 15:19.830 --> 15:25.480 Just so you know, when I started working, there are all these acronyms I didn't understand. 15:26.340 --> 15:28.140 So we have Masche. 15:28.140 --> 15:29.100 Let's turn that on. 15:29.130 --> 15:30.050 This is our grass. 15:30.060 --> 15:36.330 If you remember, it's going to slow down and we need to apply Shater to that as well. 15:36.600 --> 15:38.130 It's going to turn off the wireframe. 15:39.030 --> 15:48.180 So because it's kind of obnoxious there and let's grab this grass, which we probably need to name that 15:51.060 --> 15:52.070 just so you remember it. 15:52.080 --> 15:58.530 And that might break the mesh network because depending on that name, it looks like it worked. 15:58.530 --> 15:59.500 OK, it's still there. 16:00.030 --> 16:03.330 So with that selected, we can add Shater to that. 16:03.330 --> 16:12.330 Someone say a the material, we're going to assign a standard surface and then make this some some kind 16:12.330 --> 16:18.420 of a green something and then let's render that under Arnold or interview. 16:20.850 --> 16:21.660 Let's turn it on. 16:29.750 --> 16:32.540 Let's go to the actual renter cam view. 16:34.890 --> 16:35.790 Make sure that's. 16:36.790 --> 16:41.140 Still looks like it's pulling the perspective's, let me get Narinder Cam and make sure no, no, it's 16:41.140 --> 16:41.680 pretty similar. 16:42.670 --> 16:43.270 All right. 16:45.220 --> 16:47.950 So I'm not really seeing the grass that well. 16:49.950 --> 16:53.310 What we can do is. 16:55.070 --> 16:56.000 Crank this up. 16:56.690 --> 16:57.320 There we go. 16:59.690 --> 17:06.350 There's our grass, so it's a little bright, but, you know, want to shade it in a way that you can 17:06.350 --> 17:09.470 actually see the stuff and. 17:13.130 --> 17:17.720 Ideally, I think I'd have a lot more grass in here, but it's just kind of pretty render intensive, 17:17.720 --> 17:21.740 to be honest, I'm trying to avoid adding a ton of grass. 17:24.930 --> 17:31.500 But yeah, General, all you have to do is go back to Masche and increase this number under distribute 17:31.510 --> 17:32.900 if you wanted more right here. 17:33.720 --> 17:37.050 But in this lesson, we've learned how to create grass. 17:37.050 --> 17:38.130 We've shaded the ground. 17:38.490 --> 17:46.380 And in the next lesson, we're going to continue to shade the banners, the mud of the ground tombstone 17:46.380 --> 17:46.680 here. 17:47.010 --> 17:47.870 We're going to do the tree. 17:47.880 --> 17:49.140 We're going to give it a background. 17:50.460 --> 17:50.810 Yeah. 17:50.820 --> 17:52.180 So I'll see you in the next lesson. 17:52.200 --> 17:52.890 Thanks for watching.
