WEBVTT 00:00.480 --> 00:03.680 Welcome to reusing shaders and materials. 00:03.780 --> 00:09.930 In this video you will no longer have to keep making the same basic shaders and materials again and 00:09.930 --> 00:10.680 again. 00:10.770 --> 00:18.720 We often call for a basic wood a material plastic material a glass etc. and we have so far to create 00:18.720 --> 00:18.830 it. 00:18.870 --> 00:20.430 Every single time. 00:20.460 --> 00:25.490 But wouldn't it be great if you could just pick from a library the moment you start working. 00:26.200 --> 00:27.950 Of course it would be great. 00:28.090 --> 00:33.820 So you'll learn how to start your own library of shaders and materials so you can access them whenever 00:33.820 --> 00:35.040 you want. 00:35.170 --> 00:40.660 And this also gives you the ability to continually improve your shaders and materials and add to them 00:41.110 --> 00:43.270 as you grow as an artist. 00:43.450 --> 00:47.710 So without any further ado let's hop straight on over in a blender. 00:48.920 --> 00:52.070 Okay so in front of us we have the default blender file. 00:52.070 --> 00:59.090 So let's go ahead and I'm going to get rid of my soft cube that's there an add in a sphere because it's 00:59.150 --> 01:02.470 a lot neater and easier to work with. 01:02.510 --> 01:03.520 Scroll up. 01:03.650 --> 01:08.530 And I'm also going to shift it up on the z axis by a one blender unit. 01:08.660 --> 01:11.180 I'm now going to create a plane to work on. 01:11.180 --> 01:16.880 You can see the sort of standard workflow that I'm going through at the moment and repeatedly over and 01:16.880 --> 01:17.740 over again. 01:17.750 --> 01:25.100 Now I'm going to add a smooth shader to my sphere and I'm also going to subdivide it a couple of times 01:25.100 --> 01:28.910 just to make it super smooth and click apply. 01:28.910 --> 01:32.240 So that's a super smooth sphere on a floor. 01:32.240 --> 01:39.050 Now going to hop into rended most straightaway and minimise this down we're going to create a standard 01:39.050 --> 01:46.190 shader that we've created a couple of times already which is a mix between the gloss and a diffuse with 01:46.250 --> 01:47.800 a friend Nell mix. 01:47.840 --> 01:51.630 So let's go into the know. 01:51.680 --> 01:54.250 Ed excellent that's ad material. 01:54.260 --> 01:55.490 We don't have one. 01:55.550 --> 01:57.170 We are on the plane at the moment. 01:57.170 --> 02:03.410 Now the plane I do want to actually have something attached to it I want it to be a chequer. 02:03.410 --> 02:11.180 So for the colour input I'm going to add and texture as the input a chequered texture. 02:11.240 --> 02:13.330 And I have a plug that straight across. 02:13.340 --> 02:13.820 Perfect. 02:13.820 --> 02:17.500 I'm just going to race this scale that should make the squares smaller. 02:17.510 --> 02:18.810 I'm going to go for 20. 02:18.830 --> 02:19.630 There we go. 02:19.820 --> 02:22.820 So you've got a kind of a surface for it to work on. 02:22.950 --> 02:24.140 Right I'm happy with that. 02:24.140 --> 02:30.220 Apart from we haven't named the material so I'm going to call this chequer floor. 02:30.380 --> 02:35.470 I can just about see through my mike from the sky in front of me anyway. 02:35.570 --> 02:38.780 So we've got now this sphere to do so let's. 02:39.050 --> 02:42.580 That's not the spear that is the sphere that we've selected. 02:42.590 --> 02:45.600 Okay so we've got a diffuse shade. 02:45.620 --> 02:53.860 We need a gloss shader we need to mix those together so gloss not glue smoked glass. 02:53.870 --> 02:54.350 Excellent. 02:54.350 --> 02:58.650 Going to select them both and using control in 0 to mix them. 02:58.830 --> 03:04.250 And then the final edition is the friend nail So let's go ahead and add in. 03:04.250 --> 03:07.550 All right key combination helps friend. 03:07.600 --> 03:09.260 Now there we go. 03:09.260 --> 03:13.320 So that's a great start to that set up. 03:13.320 --> 03:18.240 Now I want to be able to control this glossy shader with a bit more finesse. 03:18.290 --> 03:22.480 In fact the glossy show there and that if you shave the roughness values. 03:22.610 --> 03:27.610 So I'm going to lower down the roughness value here and just see what's going on. 03:27.610 --> 03:31.160 Have we got the reflections that we want along the edges. 03:31.160 --> 03:33.920 Yes we have that's absolutely fine. 03:33.920 --> 03:41.010 So we're going to get on to making sure first of all that this shader is all grouped together appropriately. 03:41.140 --> 03:46.370 Now one final thing I want to do is give myself a bit more control so I'm going to add in a maths node 03:46.730 --> 03:52.700 plug the output value in both into both of those roughnesses and change that to power. 03:53.770 --> 03:56.230 Case I am liking the set up here. 03:56.320 --> 04:02.740 That is my basic set up son going to select all of the components that are with in this set up so all 04:02.740 --> 04:08.860 the way from power all the way through for a nail diffuse glossy and mix shader and I use a shortcut 04:08.860 --> 04:15.130 key we haven't grouped anything in a while but is control and she and that's going to put it into a 04:15.130 --> 04:15.720 group. 04:15.880 --> 04:19.290 Now whilst we're in this group we can start manipulating now. 04:19.300 --> 04:23.610 The output is what comes out and the input is what we can. 04:23.740 --> 04:26.350 What we actually can input control things. 04:26.350 --> 04:31.100 So for instance here I might want to control the normals for everything. 04:31.300 --> 04:34.140 I'll certainly want to control the value for everything. 04:34.140 --> 04:41.740 That's why this isn't behaving quite right so we're going to have a value slider on the group input. 04:41.740 --> 04:47.260 Now the problem with it just coming across as value is it says value over here. 04:47.260 --> 04:52.630 That doesn't mean anything let's hop out of this group with the tab key and we can see we've just got 04:52.630 --> 04:53.720 value. 04:53.860 --> 04:57.610 It's exposed that control but because it's called value. 04:57.640 --> 05:00.490 It's really no use to us whatsoever. 05:00.490 --> 05:05.950 So go back into that group and change the name of that and we can do that in the properties panel if 05:05.950 --> 05:11.500 it's not open press the N key to reveal it and we can see we've got Scott value here on the Imber and 05:11.500 --> 05:16.960 we got a name there so set of calling it value we can call it roughness because that is essentially 05:16.960 --> 05:19.050 what it's going to be controlling. 05:19.360 --> 05:20.290 Now that's in there. 05:20.290 --> 05:22.950 I'm also going to change the value of that too. 05:22.990 --> 05:24.510 I can't remember what it was before. 05:24.510 --> 05:28.680 Between 2 and 5 some may settle for 2.5 now. 05:28.690 --> 05:34.310 Other ones that you may want later Ron are your normal maps so you can control things. 05:34.330 --> 05:37.630 So I'm going to plug all of those into normal. 05:37.810 --> 05:38.220 Okay. 05:38.230 --> 05:40.840 And the final thing there I can see is the colour. 05:40.840 --> 05:42.930 So we've got some control over the colour. 05:43.030 --> 05:48.610 Now when we talk about we can see it's exposed the normal roughness and the colour sevi I lower the 05:48.610 --> 05:50.500 roughness down to point 1. 05:50.500 --> 05:57.460 It should end up a lot more glossy than it was before because should be passing on that point one across 05:57.460 --> 06:02.560 and now I can change the colour as well so I can make this a red ball of a saying you can certainly 06:02.560 --> 06:09.370 see the chequers in that much more easily okay you can see here it's actually having that fanelle value 06:09.670 --> 06:14.080 applied properly because it's getting glossier and glossier towards the outside. 06:14.350 --> 06:16.630 Excellent So there's one final thing to do here. 06:16.630 --> 06:22.330 Before we do anything else and that is to name things appropriately. 06:22.330 --> 06:27.760 This is currently called node group and that is no good at all. 06:28.150 --> 06:28.900 So let's go ahead. 06:28.900 --> 06:34.950 Properties panel here let's change node group to p.b. are plastic. 06:37.140 --> 06:38.920 And so we've got this set up now. 06:39.060 --> 06:41.380 Our plastic it's named it at the top. 06:46.000 --> 06:52.320 So we should be good to go if we need to bring that in to another one of our scenes. 06:52.360 --> 06:58.560 Now if we wanted to do this I'm going to save this file now single file save and I need it. 06:58.570 --> 07:03.310 Call it something solona called it p b r. 07:04.140 --> 07:04.880 Test. 07:06.950 --> 07:08.510 Save the blender file. 07:09.860 --> 07:10.430 Okay. 07:10.460 --> 07:16.300 The final thing I want to just check here is my material itself is called material at 001 so I'm gonna 07:16.310 --> 07:18.160 call this PBR plastic. 07:18.230 --> 07:22.520 Cause what we can then do is penned this in two other scenes. 07:22.530 --> 07:23.780 If we want to. 07:23.900 --> 07:27.610 So let's go ahead and go file save. 07:29.480 --> 07:34.440 And then actually start up a brand new blender far and we end up back here again. 07:34.640 --> 07:40.930 So now we've done that beacon go to file a and to add it into this scene. 07:41.030 --> 07:45.050 And if I go and find PBR test here we go. 07:45.320 --> 07:51.170 There are two places we can visit if we want to bring the cross the material we can see the two materials 07:51.170 --> 07:55.810 there check the floor and PBR plastic we can bring them straight into this scene. 07:56.920 --> 08:04.000 If we only want to move the node group across and set up materials afresh each time we can go to node 08:04.000 --> 08:07.360 tree and you see PBR plastic there. 08:07.980 --> 08:08.680 Excellent. 08:08.820 --> 08:10.760 Now once it's in the scene. 08:12.820 --> 08:18.980 We will need to make sure it has a fake user otherwise or a real user of course. 08:19.030 --> 08:22.810 But otherwise when you save your file it'll disappear. 08:22.870 --> 08:25.850 And of course that leads us onto a challenge. 08:27.480 --> 08:30.250 I would like you to start your library. 08:30.570 --> 08:34.950 So go ahead and add two materials to your blender start file. 08:34.950 --> 08:36.540 Remember the fake user. 08:36.540 --> 08:39.250 Otherwise it will disappear. 08:39.510 --> 08:40.180 Recommend. 08:40.200 --> 08:44.800 I do recommend a pending so the original is in the start up far. 08:44.830 --> 08:49.620 So if you've already created an awesome material in one of your other projects that you've been working 08:49.620 --> 08:55.290 on you can actually now append it into this start up file so you can use it again and again and again 08:55.710 --> 09:00.750 of course appending it means that the starter file is the source file it also means if you need to change 09:00.750 --> 09:03.170 something you can change it in the starter file. 09:03.270 --> 09:09.530 Just remember to save it save your start-up file to make sure that you've solidified that change. 09:09.540 --> 09:15.780 The one thing I would impress upon you is remember what you're seeing on your screen at the moment. 09:15.780 --> 09:22.140 You save your start-up file is exactly what's going to appear every time you start a brand new blender 09:22.140 --> 09:22.740 file. 09:22.740 --> 09:27.690 So make sure you sort things out and tidy up just before you hit back save. 09:28.080 --> 09:32.050 Go ahead and also add to node groups to your start-up file. 09:32.190 --> 09:38.370 So have you found yourself not only having to set up obviously repeats materials all the time but have 09:38.370 --> 09:44.280 you also found yourself having to set up basic node groups again and again and again are you always 09:44.280 --> 09:46.470 doing glossen to fuse in a mix shader. 09:46.470 --> 09:51.930 Well why not group them together so you can just put them into your scene very quickly. 09:51.930 --> 09:58.110 We've already seen that node Wrangler auret Automatically assigns a texture mapping with control in 09:58.110 --> 10:01.680 t automatically adds those three nodes in there. 10:01.680 --> 10:07.920 That's kind of like how this is going to work but only add useful things of this group rather than things 10:07.920 --> 10:09.540 that take seconds to do. 10:09.570 --> 10:14.490 Obviously we're practicing at the moment but later on you'll want to do this with more complicated things 10:14.790 --> 10:17.060 so you don't have to keep setting it up. 10:17.070 --> 10:18.170 Every single time. 10:18.180 --> 10:21.320 Certainly speed up your work flow no end. 10:21.390 --> 10:26.440 Finally consider anything you repeatedly had to set up over and over again. 10:26.460 --> 10:31.890 It's important that this is not a shortcut to just doing something once or for a simple task. 10:31.890 --> 10:36.630 This is a shortcut to stop you having to do the same thing repeatedly. 10:36.660 --> 10:42.450 Now you might want to consider also in your scene a series of test objects to test out your materials 10:42.720 --> 10:44.220 and demonstrate them. 10:44.220 --> 10:48.570 Now you may also want to consider not putting these on Layer 1. 10:48.960 --> 10:54.090 So if you need a preview in test materials you switch yourself over to one of the other layers so you 10:54.090 --> 10:55.660 can work on it from there. 10:56.010 --> 11:00.210 But if you just want to get on with your work you don't have to worry about removing those other objects 11:00.210 --> 11:01.060 from the scene. 11:01.230 --> 11:05.090 And of course hide them away if necessary as well. 11:05.090 --> 11:06.280 In the outliner. 11:06.360 --> 11:11.070 Put them under a an empty called Test objects or something like that so you can keep them out of the 11:11.070 --> 11:17.610 way of being rendered accidentally so you can keep them out of the way in general aswell so borza video 11:17.610 --> 11:23.940 this might take you a little while to practice and sort out and bring some new materials into your library 11:23.940 --> 11:32.090 perhaps try a couple of textures as well in there perhaps rock or wood as two examples how you can do 11:32.100 --> 11:40.030 your desks or floors outside concrete things like that supports a video now and give that a go. 11:42.410 --> 11:43.130 Okay guys. 11:43.130 --> 11:44.260 Welcome back. 11:44.270 --> 11:48.850 Let's go to materials and to know groups over in my Start-Up file. 11:51.140 --> 11:56.590 Saan going to append this PBR plastic into my file since it's already on the screen ready to go. 11:56.720 --> 12:01.670 And I'm also going to go ahead and spend that other material. 12:01.840 --> 12:05.780 PBR last if I could a pen a floor as well. 12:05.810 --> 12:08.870 And let's move this test object. 12:08.870 --> 12:10.040 Well that's not a test object. 12:10.060 --> 12:11.500 Let's get rid of that. 12:11.510 --> 12:15.090 I am going to move in my chequered material actually as well. 12:15.230 --> 12:18.510 So let's go ahead and pen the chequered floor. 12:18.830 --> 12:24.130 I'm just going to construct a basic scene so I've got a plane I'm going to scale that up. 12:24.200 --> 12:28.020 I'm going to go to my materials and there should already be a check a floor there. 12:28.070 --> 12:33.170 Now of course if I apply these to objects now I don't need to give them a fake user but whilst I'm here 12:33.170 --> 12:40.400 I am going to give them a fake user as well so that if any points I decide to remove it from these objects 12:40.430 --> 12:44.970 while I'm practicing I'm not going to remove them from this blender. 12:45.260 --> 12:51.650 Some going to go ahead here with this plane and move it to l.a. and I'm going to move it to the rear. 12:51.650 --> 12:52.770 The last layer. 12:52.790 --> 12:54.390 And I'm going to go to that layer. 12:54.610 --> 12:54.910 Okay. 12:54.920 --> 12:56.390 Now from this last layer. 12:56.740 --> 13:02.630 And when I add in a couple of mesh objects I'm going to add in Suzanne the monkey and hunger. 13:02.880 --> 13:03.410 G. 13:03.440 --> 13:04.170 Z one. 13:04.190 --> 13:06.800 And I'm going to move my 3-d cursor. 13:07.960 --> 13:12.340 To Z equals one as well so these next few that I add so are seen. 13:15.580 --> 13:22.230 Move Suzanne along from there yet the next ones I add to the scene here I'll be able to see straightaway. 13:22.360 --> 13:28.620 I'm going to have mice ecosphere as faceted one because it just looks cool as a crystal. 13:28.790 --> 13:31.060 And what shall I had finally. 13:31.340 --> 13:36.480 Let's had a Taurus have not added to Taurus for a while and glamour tourist nice and smooth as well. 13:36.490 --> 13:43.810 So I've got my various objects here Suzanne I am going to subdivide a couple of times subdivisions surface 13:43.810 --> 13:44.840 modifier. 13:45.820 --> 13:47.780 And add smooth shading. 13:47.830 --> 13:52.600 I'm going to do a very similar thing to my sphere but not so many. 13:52.600 --> 13:56.730 All I did was solidify I want subsurface division. 13:58.050 --> 13:59.680 Apply and smooth that out. 13:59.680 --> 14:00.460 That's agony. 14:00.490 --> 14:01.380 Leave like that. 14:01.530 --> 14:05.570 Now I am also going to make this one nice and smooth as well. 14:06.330 --> 14:12.970 And make it a smooth shade so I've got my few objects here and I'm just going to move my camera to reflect 14:12.970 --> 14:18.300 that obviously this is gonna change the default camera position but I don't care. 14:18.310 --> 14:22.900 In this case now going to add this flaum will go into rended mode. 14:22.900 --> 14:24.950 This floor is currently got PBR plastic. 14:24.950 --> 14:26.840 I'm going to change it to. 14:27.580 --> 14:28.520 Check the floor. 14:28.600 --> 14:29.460 Excellent. 14:29.500 --> 14:35.450 Seems a little dark in here for some reason and I'm not quite sure why ever turned off a lamp or anything. 14:35.470 --> 14:37.750 No I won't. 14:37.750 --> 14:39.990 It does seem up to. 14:40.300 --> 14:42.040 Yes the lamps on like one. 14:42.040 --> 14:42.960 Fair enough. 14:42.970 --> 14:44.560 I can see what's going on there. 14:44.740 --> 14:51.630 Okay so my ball here has got a PBR plastic on it cause I'm already in the start-up up file here. 14:51.760 --> 14:57.400 I can create my materials afresh in this file or together some long ago new here. 14:57.420 --> 15:03.290 I only call this crystal c r y s t l o vissel K. 15:03.430 --> 15:06.700 It does not help when you cant really see the keyboard underneath. 15:06.700 --> 15:10.880 So we got Crystal here and Anna say that to a glass shader. 15:12.270 --> 15:13.720 Okay so we've got V. 15:13.770 --> 15:20.880 The crystal surface here am now going to go into the node editor itself and see if we can refine this 15:20.910 --> 15:27.120 a little further and I'll be back in a few moments once I've tweaked about for a few minutes. 15:27.420 --> 15:29.990 Okay so a little bit of a lie there. 15:29.990 --> 15:33.110 I spent quite a bit of time rather than have fume. 15:33.120 --> 15:40.470 It's just playing with my set up here so I've moved everything over to lay low or the very final layer 15:40.470 --> 15:48.030 here and as we can see by look at the examples here I've turned off everything but the lamp in this 15:48.060 --> 15:55.340 last layer which is a an exact duplicate of the first lamp on layer one has turned everything on. 15:55.350 --> 16:02.790 As we've said we've got a we've got a series of items here and a series of materials as well a pick 16:02.790 --> 16:05.940 from I remember to give them all a fake use to survive. 16:05.940 --> 16:08.310 You decide to delete any of these or don't. 16:08.370 --> 16:12.660 The actual model themselves I don't delete the actual material. 16:12.870 --> 16:16.190 Let's just have a quick look at how all those look. 16:16.200 --> 16:18.240 Take a few moments to render out. 16:18.660 --> 16:23.320 Okay so that's finished rendering out there and we've basically got a chequered floor. 16:23.550 --> 16:29.090 A plastic ring a terracotta teapot a fire ball or just something. 16:29.100 --> 16:32.840 I was playing around with and came up with something quite fanciful there. 16:33.030 --> 16:39.260 A wooden monkey and this faceted sort of gem crystal type thing. 16:39.280 --> 16:44.910 I've been working on there so we can take a look at a couple of these you don't have time for a deep 16:44.910 --> 16:46.760 dive into any of them. 16:46.800 --> 16:48.030 Which ones should we have a look at. 16:48.030 --> 16:55.440 Let's have a look at this tea pot here so I'm going to hide everything else. 16:55.440 --> 17:01.710 Starting to render out here we can see that this terracotta teapot has a texture to the surface. 17:01.710 --> 17:05.990 So let's go have a look at the notes set up and see how that one was set up. 17:09.000 --> 17:11.480 Okay so we'll start at the far side. 17:11.490 --> 17:15.060 The right hand side because this is pretty familiar to us. 17:15.120 --> 17:22.530 We've got our two notes that are quite standard diffusing glossy chaser's mix and for for a knells shader 17:22.830 --> 17:25.780 into a mix shader and to the material outputs. 17:25.800 --> 17:29.990 Now the difference comes this side and it's literally just a texture. 17:30.090 --> 17:32.810 So let's have a look at how it's structured. 17:32.820 --> 17:40.560 First of all we've got a texture coordinates now the texture claudina Simply tells blender how to map 17:40.740 --> 17:48.750 the actual texture to the surface of our object subset its object so it generates the coordinates for 17:48.750 --> 17:54.480 us without having to worry too much about any seams or anything along those lines and because we're 17:54.480 --> 17:57.520 just using a noise texture and nothing else. 17:57.840 --> 17:59.070 That's absolutely fine. 17:59.130 --> 18:01.690 In fact this noise texture here. 18:01.920 --> 18:05.470 If we isolate it we can see what's going on. 18:05.470 --> 18:12.660 So um troll shift and click VAT's and then click it again take a few seconds Blender's running a little 18:12.660 --> 18:14.310 bit slowly for me. 18:14.880 --> 18:16.490 Or not responding. 18:18.460 --> 18:19.060 There we go. 18:19.060 --> 18:20.970 I don't know why that was being a bit slow there. 18:20.970 --> 18:26.650 I think I'm just having a bit of a slowness issue on the computer anyway so we can see that we've got 18:26.650 --> 18:32.800 a black and white output from this noise texture and it kind of looks like some clouds I suppose. 18:32.800 --> 18:38.140 Now this is being put into the bump anode and when that happens is being plugged into the height of 18:38.140 --> 18:38.660 the bump. 18:38.670 --> 18:46.340 My notes so we've got high points and low points and that is being spat out as a normal. 18:46.510 --> 18:50.580 So we go to the bump the head itself ends preview that. 18:51.540 --> 18:52.220 There we go. 18:52.230 --> 18:53.100 We can see. 18:53.130 --> 18:57.060 We get a textured output from it. 18:57.060 --> 19:02.910 Now when we have a look at these individually you can see that the glossy has a little bit of an effect 19:02.910 --> 19:03.570 on it. 19:03.630 --> 19:05.890 The diffuse has a lot. 19:06.560 --> 19:09.510 But even more is the for a nail itself. 19:09.610 --> 19:17.750 It's affected massively by the actual normal mapping is self and that gives us the nice sets of textured 19:17.810 --> 19:20.350 results over the top of the surface. 19:20.360 --> 19:25.790 Of course we can play we can make it look even more mottled by simply increasing the strength to maybe 19:25.790 --> 19:32.790 point five really starts to bring out those particular bumps in the surface of the terracotta. 19:33.050 --> 19:33.620 Excellent. 19:33.620 --> 19:37.580 How did you guys get on what materials did you end up creating. 19:37.580 --> 19:42.980 I've obviously gone for Terry Cotterell and some other wacky ones here and obviously I can branch out 19:43.010 --> 19:45.080 and create more as we go on. 19:45.080 --> 19:50.180 Remember to share your materials that you've made in the discussions in fact link a blend file there 19:50.240 --> 19:53.340 as well so we can she share our materials. 19:53.360 --> 19:57.600 As you start making them and I will see you in the next lecture.
