WEBVTT 00:00.890 --> 00:05.330 Welcome to the introduction to the node editor in this video. 00:05.360 --> 00:10.440 You will open up the node editor create some basic materials. 00:10.640 --> 00:17.920 Apply these materials to our model and see how adjustments in the node editor affect our model. 00:18.320 --> 00:21.180 So let's hop straight on over into a blender. 00:22.610 --> 00:25.480 Right over in glendive there's a couple of things we'll need to do. 00:25.480 --> 00:29.350 First of all I'm going to turn my back drop back on. 00:29.510 --> 00:32.620 I'm going to turn out the camera doesn't matter at this point in time. 00:32.660 --> 00:33.340 The cone. 00:33.390 --> 00:37.900 Well that was a positional cone and now makes no sense to have anymore. 00:37.920 --> 00:38.890 I'm going to delete. 00:38.900 --> 00:40.770 That's from our scene. 00:40.820 --> 00:46.490 Looking down the list here I've got the lamp that was there and the plane a want to turn both of those 00:46.490 --> 00:52.130 on so our light sources are in the ceiling because the node Ed is all to do with cycles render. 00:52.580 --> 00:56.120 So and further down here I think that's all we need to turn on. 00:56.120 --> 00:58.340 Don't need to see the rig for this next bet. 00:58.520 --> 01:00.660 Now we need to add the node editor. 01:00.860 --> 01:06.210 So I'm going to go to the splitter widget on the 3d Ed header and just pull that down. 01:06.440 --> 01:12.320 And probably about 50/50 for me with my resolution here. 01:12.680 --> 01:12.950 Okay. 01:12.960 --> 01:18.080 And I'm going to change this bottom one to node editor which is just here so we're changing the window 01:18.080 --> 01:19.830 type to the node editor. 01:20.180 --> 01:22.790 And it just looks like this space here at the moment. 01:22.790 --> 01:23.600 Great. 01:23.630 --> 01:27.600 I'm also going to just pan up here. 01:27.770 --> 01:32.750 I'm going to start focussing on the base of our lamp to speed up render times. 01:32.750 --> 01:40.670 I'm going to use control and B and just draw a box around our the bottom of the lamp basically so we 01:40.670 --> 01:41.420 can see what's going on. 01:41.420 --> 01:46.090 In fact I'm going to zoom in a little more so that's filling up the screen. 01:46.100 --> 01:51.410 Then I'm just going to draw another border that's just slightly bigger than when I switch on cycles 01:51.710 --> 01:55.170 render at the top here which it is and go to rendered view. 01:55.220 --> 02:00.530 It will only render this area here and I can see that there's light coming in from our plane and everything 02:00.530 --> 02:02.260 else great. 02:02.300 --> 02:10.230 So I'm actually going to create our new material straight away over in the materials tab over here. 02:13.570 --> 02:19.740 So I'm going to create a new material and you can see two things straightaway appeared in the node editor. 02:19.930 --> 02:25.960 And for now I'm just going to push this away to one side so we can see what's going on in the screen 02:25.960 --> 02:27.040 in front of us. 02:27.040 --> 02:31.450 I'm going to zoom in here because I can't read that at the moment so you definitely can't. 02:31.690 --> 02:34.590 And we've got two items in front of us. 02:34.600 --> 02:39.930 These are nodes now nodes cans consist of different types. 02:39.940 --> 02:47.320 If we go down to add on the header we can see there are lots of different types of nodes that we can 02:47.320 --> 02:54.930 have for the moment we're going to be dealing with shaders which is what a diffuse node is. 02:55.090 --> 03:02.200 And the material output that's what we'll actually see and we're connected here with two lines so we 03:02.200 --> 03:07.180 got the output here going all the way to the surface material here. 03:07.180 --> 03:12.870 If I click and drag that our way from there it literally disappears. 03:12.880 --> 03:18.640 But because it's the same as the default material at the moment it looks no different if I was to change 03:18.640 --> 03:22.130 this colour here to something else. 03:22.180 --> 03:22.670 There you go. 03:22.660 --> 03:24.120 I'm going to make it bright red. 03:25.910 --> 03:27.410 Try make it bright red. 03:29.430 --> 03:32.380 I can see a great cast in our scene. 03:32.400 --> 03:37.180 And I've I think we've coloured in something else yes we have. 03:37.320 --> 03:41.340 So let's select our base first. 03:41.520 --> 03:42.630 I didn't select the base. 03:42.630 --> 03:48.900 Silly me and I'm literally going to select from the materials here material and I'm going to name that 03:48.900 --> 03:50.810 material whilst I'm here. 03:50.970 --> 03:57.720 Red Lamp paint you can choose a different colour if you like I just like the colour red. 03:57.750 --> 03:59.040 In this instance. 03:59.190 --> 04:05.670 Okay so we've got a red lamp and if I pull the surface connector out it goes black it's got no material 04:05.670 --> 04:06.570 assigned to it. 04:06.720 --> 04:08.860 So let's connect those back up again. 04:09.280 --> 04:10.950 Now unlike. 04:11.550 --> 04:17.700 Blend a render way you can add the two things together over in the side you can't do that with this 04:17.700 --> 04:19.840 materials property on the right hand side. 04:19.840 --> 04:22.260 Some just going to make that disappear. 04:22.260 --> 04:27.690 Now what we need to do here and I'm just going to squish it up a bit further to give myself a bit more 04:27.690 --> 04:32.270 space and I'm going to zoom out here hopefully you can still read what's going on. 04:32.430 --> 04:35.450 I need to add another shade up. 04:35.670 --> 04:41.910 So like anything else in blender you can either go down to the admen you hear I'm going to use the shortcut 04:41.910 --> 04:43.970 key shift and a. 04:49.280 --> 04:52.570 So shift and a will bring up the ADD menu. 04:52.760 --> 04:55.410 Now I'm going to be looking for the shade. 04:55.700 --> 05:00.980 There is a mix shader which is at the top but there's a very quick way if you know what you're looking 05:00.980 --> 05:07.030 for in this case a mic shader I'm going to type in honour of click on search and type in Mc shater. 05:07.030 --> 05:09.540 Looks like that was the last one I was indeed looking for. 05:09.710 --> 05:12.200 And that will add a mix schade a node in. 05:12.200 --> 05:19.460 Now if you hover a node over the top of a connector it will automatically join them together for us. 05:19.760 --> 05:21.260 So that's that done there. 05:21.260 --> 05:27.730 So we've now got a 50 percent that's got this factor here means of diffuse shader. 05:27.800 --> 05:33.660 So it looks all mapped going to our material output which is what we see on the screen. 05:33.770 --> 05:38.260 Now I want to give it a bit of secularity a bit of reflection. 05:38.330 --> 05:44.510 So in order to do that I need to add what's called a glossy shader So I'm going to go down to shaders 05:44.510 --> 05:48.400 and just have a quick look down here and there we go glossy. 05:48.830 --> 05:54.340 If I add that I'm going to place it next to here you can place these wherever you like. 05:54.350 --> 06:00.890 But for organizational purposes I like to keep these things together and the outputs here I'm going 06:00.890 --> 06:06.700 to plug into this second shader area and you can see we're starting to get in. 06:06.710 --> 06:07.890 Interesting. 06:10.080 --> 06:11.240 Render at the top. 06:12.790 --> 06:13.220 Right. 06:13.240 --> 06:15.300 So let's play about with these a little more. 06:15.310 --> 06:20.950 I don't like what's come out there so I'm going to move this to the left or the right and see if we 06:20.950 --> 06:23.910 can get what I think is a better mix. 06:23.990 --> 06:27.870 This will be around a 20 percent mix that does look a lot better. 06:28.300 --> 06:34.960 Now with the glossy shader there is a series of selections you can go for. 06:35.020 --> 06:39.970 The only one that really makes a difference that I can see is sharp in our particular model. 06:39.970 --> 06:43.720 It just produces a sharp reflection full stop. 06:43.870 --> 06:48.370 If I pick any of the others they all look relatively similar. 06:48.670 --> 06:53.440 Now whilst this is rendering a way at the top here is only 10 samples. 06:53.470 --> 06:56.710 So what I'm going to quickly do is pull this out on the side. 06:56.710 --> 07:03.850 I'm going to go to the render properties and scroll down to where we have the sampling and I'm going 07:03.850 --> 07:07.650 to turn the number of samples up in our preview too. 07:07.770 --> 07:09.000 I'm going to do a hundred. 07:09.000 --> 07:10.840 You don't have to go that high. 07:11.200 --> 07:15.260 And so it will get better and better as I wait. 07:15.280 --> 07:18.690 Every time I change something you will have to start zero again. 07:18.790 --> 07:23.030 But that's not a big deal for me at the moment because we're only rendering a small area in fact something 07:23.050 --> 07:25.880 to make the render area just slightly smaller again. 07:26.750 --> 07:27.320 X. 07:27.610 --> 07:30.710 So I'm still not a great fan of what's going on here. 07:30.790 --> 07:32.160 This rough from the slide. 07:32.180 --> 07:34.500 Well that is very useful when it comes to the glossier. 07:34.500 --> 07:36.740 We turn it all the way up to 100 percent. 07:36.790 --> 07:38.480 It just looks like Matt. 07:42.400 --> 07:43.860 It just looks matter again. 07:44.020 --> 07:49.840 If we lower it all the way down to nothing it goes super glossy as if we had just selected sharp here 07:49.840 --> 07:51.340 on the distribution. 07:51.790 --> 07:53.970 However after playing with oh look at that. 07:54.100 --> 08:00.100 If we zoom in a little here we can actually see it's reflecting the rest of the lamp up the top. 08:00.100 --> 08:00.920 That's brilliant. 08:00.940 --> 08:04.800 So I want to keep some of that reflection in our model. 08:05.440 --> 08:07.260 So I'm going to play with this roughan set. 08:07.270 --> 08:11.050 I'm going to start with point so and see if that is high enough. 08:11.080 --> 08:13.120 Let's zoom in a little. 08:13.150 --> 08:14.700 No I want something a bit lower. 08:14.700 --> 08:15.830 I'm going to try point one. 08:15.910 --> 08:17.920 And a lot of this is about experimentation. 08:17.920 --> 08:20.180 I can see the reflection is there. 08:20.260 --> 08:24.210 It's not really well defined but it is there and that's what I want. 08:24.220 --> 08:26.550 So this is going to pull out a little here. 08:26.890 --> 08:29.270 Okay that's starting to look really good. 08:29.290 --> 08:35.650 Unlike in the output here this factor here again if I moved all the way to one side you just see the 08:35.650 --> 08:41.800 shiny parts of it and it looks like we've got some weird artefacts going around the base here so be 08:41.800 --> 08:49.100 worthwhile trying to clean that up in a few moments and we can bring in the rest of our culture which 08:49.110 --> 08:52.210 is are diffuse over here into a scene. 08:52.210 --> 08:58.310 In fact I quite like the setting I've managed to get there which is about 30 percent coming through 08:58.450 --> 09:00.570 that's glossy right. 09:00.580 --> 09:04.310 Let's see if we can quickly and bring up the. 09:05.920 --> 09:07.400 Head a bar over here. 09:07.420 --> 09:16.180 And just to see whether we can go in and edit this and puts another loop cut in just around here. 09:16.180 --> 09:22.480 And I'm going to bring it out ever so slightly to give it more of a base and see how that affects our 09:22.540 --> 09:23.770 renderer itself. 09:23.770 --> 09:30.860 To see if that makes a difference that gives a much more defined edge and doesn't look so nasty anymore. 09:31.000 --> 09:35.780 So you can see by applying the render soon on in the model of we've actually gone through and rendered 09:35.830 --> 09:40.100 this a little bit earlier would have been able to correct that geometry as we were going. 09:40.450 --> 09:41.270 That's brilliant. 09:41.410 --> 09:42.840 I think it's Challenge time. 09:45.260 --> 09:49.120 I would like you to add material to the rest of the scene. 09:49.990 --> 09:52.170 Play with the materials in the node editor. 09:52.180 --> 09:58.080 Have fun with it create at least two different materials by using the node editor. 09:58.420 --> 10:04.960 Remember you have a material on the back drop to see you can add a different type of material to that 10:05.320 --> 10:10.540 and make sure you assign your new materials to the rest of the lab so that nothing is left with the 10:10.540 --> 10:15.360 default material pulls the video now and give that a go. 10:16.820 --> 10:17.680 Okay guys. 10:17.810 --> 10:18.710 Welcome back. 10:18.890 --> 10:21.200 Let's hop straight over into blender. 10:22.620 --> 10:22.890 Right. 10:22.890 --> 10:24.380 So back over in bland. 10:24.390 --> 10:29.770 I'm just going to pull this down a little so I can see what's going on. 10:29.850 --> 10:32.510 Let's have a look at what we've got so far. 10:32.670 --> 10:36.650 So there are a couple of other bits of our model to apply materials to. 10:36.720 --> 10:41.170 I think I'm going to keep my ball joints just a separate colour for the moment. 10:41.340 --> 10:43.380 And this one down the bottom here. 10:43.410 --> 10:45.780 I've gone behind my scene by the looks of things. 10:45.810 --> 10:52.170 So this stem I think we've called it so let's have a look at the stem now and I'm going to call this 10:52.560 --> 10:54.360 metal again. 10:54.420 --> 10:57.710 I'm just going to play with how this turns out. 10:57.960 --> 11:00.230 Let's pull that up. 11:01.030 --> 11:02.660 Let's pull that up there. 11:02.750 --> 11:05.960 And this is actually rendering quite a large area. 11:05.970 --> 11:07.740 So I'm going to. 11:09.040 --> 11:13.090 Draw a new area around here so you can just watch it and about. 11:13.120 --> 11:20.190 I'm going to add a nother one and it's going to be shader loss. 11:21.610 --> 11:23.350 Only worked with those at the moment. 11:23.350 --> 11:29.380 I also want to add a mix shader which is oh I've run out of screen space there for that. 11:29.590 --> 11:32.100 I would go over top of that the whole add it in. 11:32.100 --> 11:33.840 And I'm going to add another one. 11:34.180 --> 11:40.790 Okay so metals a little shinier than paint in general and it tends to be kind of greying calories. 11:40.810 --> 11:47.950 So some are going to make it a dark grey and I'm going to go more towards that dark grey Oh no increase 11:48.910 --> 11:51.550 or decrease the amount of roughness. 11:51.550 --> 11:54.440 Not completely about there. 11:55.970 --> 11:57.040 How are we getting on there. 11:57.050 --> 11:57.780 That's. 11:59.750 --> 12:02.500 Zoom in a little and see how that's looking. 12:02.850 --> 12:04.440 We'll keep going behind the scene. 12:13.210 --> 12:13.570 Okay. 12:13.570 --> 12:16.360 That's looking pretty good. 12:16.370 --> 12:18.380 Let's see what it looks like with the. 12:18.550 --> 12:20.480 All the way with that all the way up now. 12:20.530 --> 12:22.700 Let's just raise a little bit more. 12:25.090 --> 12:25.720 Okay. 12:25.810 --> 12:33.100 The rest of this these arms um can actually give those leclair my. 12:33.640 --> 12:36.680 Selection for the moments we get. 12:36.730 --> 12:41.770 I'm going to give these arms the same material so I can go to the material properties here and do red 12:41.770 --> 12:46.850 lamp paint and I'm going to do the same for the lower arms. 12:47.860 --> 12:48.740 There we go. 12:48.940 --> 12:54.980 So it just leaves this ball joint here and I think I can neaten that up later on I'm not going to do 12:54.980 --> 12:56.050 it at the moment. 12:56.110 --> 12:59.810 I'm going to add in the metal one there. 13:00.190 --> 13:02.440 Okay so now I've got those. 13:02.470 --> 13:08.090 In fact the metal one I am going to make it highly reflective so I'm literally going to set it to sharp. 13:08.140 --> 13:11.160 So it just reflects everything that's rounded. 13:11.620 --> 13:15.040 Okay so that's the basic lamped done I'm going to have the back drop. 13:15.280 --> 13:16.980 So let's have a bit of fun with the backdrop. 13:16.990 --> 13:19.810 I'm going to add a new material and I'm going to call it back drop. 13:19.990 --> 13:22.570 Very important to name your material so you know what's going on. 13:22.570 --> 13:24.080 The back drop. 13:24.260 --> 13:26.560 Now I've got loads and loads of choices. 13:26.560 --> 13:34.360 I mean that could essentially change this to use the delete that hit X and delete it because now it's 13:34.360 --> 13:36.010 got no material so it disappears. 13:36.010 --> 13:38.850 I'm going to add a shader. 13:39.990 --> 13:41.270 That's just glossy. 13:41.370 --> 13:42.720 Let's see what happens if we do this. 13:42.720 --> 13:43.890 I'm just having fun. 13:43.900 --> 13:45.850 It might go horribly wrong. 13:45.960 --> 13:49.950 So with the roughnesses 20 we actually get a reflection going on. 13:49.950 --> 13:58.320 Obviously if we turn all the way down we end up with a very very shiny mirror and Oh how does that look 13:58.460 --> 14:03.500 has got to be another reflection going on some points over here. 14:04.740 --> 14:05.810 Or maybe not. 14:06.080 --> 14:06.450 No. 14:06.540 --> 14:08.320 No other reflection going on there. 14:09.090 --> 14:09.660 Wow. 14:09.690 --> 14:15.900 Okay so let's just CERN up the roughness ever so slightly. 14:15.990 --> 14:17.270 I might leave it like that. 14:17.280 --> 14:20.530 I don't know if it's a bit too shiny. 14:20.790 --> 14:23.210 But I will give it a different colour. 14:23.940 --> 14:28.960 No still no blue does go well with it. 14:29.820 --> 14:31.170 Red But no. 14:31.200 --> 14:32.410 How about an orange. 14:32.430 --> 14:33.740 A deep orange. 14:34.750 --> 14:35.690 Oh that's quite nice. 14:35.690 --> 14:41.360 Quite a warm scene now although the problem with just having it reflective like that is it does look 14:41.360 --> 14:44.170 more like the lamps floating than anything else. 14:44.180 --> 14:48.640 So I will add in another diffuse shade. 14:49.670 --> 14:53.190 And a mix shade just some research from MCs showed up. 14:54.040 --> 14:55.010 Add that in. 14:56.220 --> 14:56.930 This one in here. 14:56.940 --> 14:57.680 I'm not going across. 14:57.870 --> 15:04.620 Not going to devour across them back over and I'm going to set the colour down here as again a deep 15:05.850 --> 15:11.860 deep colour there and slowly just turn it a bit up Pierce a bit more shiny. 15:12.210 --> 15:12.920 Excellent. 15:13.630 --> 15:16.430 Still looks a bit like it's floating though. 15:16.780 --> 15:18.680 That might just be me. 15:18.820 --> 15:21.760 Not in the right position or waiting for it to render out. 15:21.790 --> 15:23.730 Actually no it looks absolutely fine. 15:24.610 --> 15:25.550 Okay that's great. 15:25.570 --> 15:32.350 I'd love to see what you guys have come up with your rendering of your lamp and shortly we'll be making 15:32.350 --> 15:33.910 this one move. 15:35.540 --> 15:38.890 Until then I will see you in the next lecture.
