WEBVTT 00:00.120 --> 00:03.180 Welcome to applying a normal map in blender. 00:03.360 --> 00:08.490 So this is going to be the continuation from the challenge in the last lecture where we create a normal 00:08.490 --> 00:10.950 map just to remind you of that challenge we're going to take. 00:10.950 --> 00:16.290 One of the models up to at least 10 levels say Now I've already done that because it takes quite a while 00:16.290 --> 00:17.560 to do some modelling. 00:17.660 --> 00:23.040 And we're going to create a normal map of that and apply it to a lower polygon model and then finally 00:23.040 --> 00:26.840 are share the two side by side so we can see which is which. 00:27.000 --> 00:29.620 So let's hop straight on over in a blender. 00:29.760 --> 00:34.620 Okay so I've opened up my window and this is the file that I have been working on. 00:34.680 --> 00:44.760 I've got my elodie B and I've also been working on an L O D C so let's enable that and this is what 00:44.760 --> 00:50.610 it looks like he's got a few quirks here in there but overall I'm happy with the outcome. 00:50.610 --> 00:55.720 It looks much more higgledy piggledy than another one would. 00:55.890 --> 01:00.930 So there is a couple of things that we need to think about before I go forward and the first one is 01:00.930 --> 01:07.260 this material now in a moment I'm about to build up a new material based upon my original wall but it 01:07.320 --> 01:10.870 is going to be unique to this particular model. 01:10.950 --> 01:16.530 So in that case I don't think I need it linked anymore because as soon as we apply the normal map there 01:16.560 --> 01:21.540 is specifically for this model simply because it's got a hole in the middle. 01:21.630 --> 01:26.750 We are well we can't link it anymore so we can actually break that link completely. 01:26.760 --> 01:32.530 And I've clicked the little icon there so it's now local to this particular model. 01:32.970 --> 01:36.830 Okay so now that we've done that I'm broken that's a wall link. 01:36.840 --> 01:41.040 We can now start working on the model a little further. 01:41.040 --> 01:46.780 The first well I'm not sure what order to do this in that it doesn't really matter in many ways but 01:46.820 --> 01:49.410 I'm trying to go through it in a logical manner. 01:49.410 --> 01:52.450 I think I need to deal with the multiple you v maps. 01:52.500 --> 02:00.570 I know we with an image so let's create a new image and call it window normal 44. 02:00.920 --> 02:03.240 Oh that's badly spelt normal. 02:03.240 --> 02:04.040 There you go. 02:04.050 --> 02:10.360 And if we now have a look at the U V map if we try and bake to this image it's going to cause a problem 02:10.360 --> 02:11.250 and show you that. 02:11.250 --> 02:15.950 Now let's see if we can bake straight away Sir elodie see to elodie B. 02:16.020 --> 02:16.930 That's fine. 02:17.370 --> 02:19.860 Is selected Let's scroll down here. 02:19.860 --> 02:21.380 Go to break. 02:21.720 --> 02:24.790 And we want normal selected to active. 02:24.810 --> 02:27.710 And the race distance I'm going to go for points. 02:28.150 --> 02:29.540 Not sure of it's going to be OK. 02:29.670 --> 02:32.260 No active image found in material wall. 02:32.270 --> 02:35.430 Okay so we run the risk here of overwriting an image. 02:35.430 --> 02:39.200 If we're not careful so let's proceed with caution. 02:39.210 --> 02:39.770 Okay. 02:39.950 --> 02:41.290 It's currently assigned. 02:41.310 --> 02:47.130 We've got the wall texture here and that possibly the wall material and the texture that we're trying 02:47.130 --> 02:48.990 to write to is a generated texture. 02:48.990 --> 02:51.360 So we need an image texture. 02:51.360 --> 02:53.960 And here is the church block work. 02:53.970 --> 02:56.390 We don't want that we want the window normal. 02:56.380 --> 03:02.120 So I've swapped over to that that's now our active image and I'm going to hit bake. 03:03.360 --> 03:03.810 Excellent. 03:03.810 --> 03:06.060 So that's done exactly what I thought it was going to do. 03:06.060 --> 03:08.110 It's updated the. 03:08.290 --> 03:14.220 Wow that looks absolutely out of the sky but anyway so you can see here that the UV map is too big for 03:14.220 --> 03:16.160 the image so we can go and sort that out. 03:16.160 --> 03:17.340 That's not a problem at all. 03:17.340 --> 03:20.130 We need to basically scale that image in. 03:20.190 --> 03:27.750 So I'm going to go ahead or scale not the image sorry the movie map in but we need a new you v map first 03:27.840 --> 03:34.020 so I'm going to go to you v maps in the data properties and then add a new You've come out and I'm going 03:34.020 --> 03:37.220 to call it normal map instead. 03:38.420 --> 03:44.420 Now that I've got a normal map there we can go ahead and just bring this up so I can see what's going 03:44.420 --> 03:44.910 on. 03:45.080 --> 03:51.920 I can hide elodie see from my scene for the moment so I can see what's going on and what I can do here 03:52.040 --> 03:55.150 is stop in the edit mode real quick. 03:55.460 --> 03:58.090 Bring this back down so I can see what's going on. 03:58.190 --> 04:01.600 And I actually only need one of these on. 04:02.730 --> 04:04.520 On this particular image here. 04:04.530 --> 04:11.380 So I'm going to scale that in is snappin turned on no it's not a scale that down and move it. 04:11.490 --> 04:15.870 So I don't need the whole image on because I actually only care about the front. 04:18.920 --> 04:21.980 So let's move down to there. 04:24.420 --> 04:34.530 Now when we're actually mapping I do care about these two being on top of one another so this bit here 04:34.560 --> 04:39.990 and this one here being on top the front of the back on top of one another because they'll be projecting 04:39.990 --> 04:42.570 different Normal's onto one another. 04:42.660 --> 04:48.710 And now that I've rearranged that we can make no valid cited options there too there. 04:48.750 --> 04:50.500 Make sure we can see it. 04:52.600 --> 04:53.640 Okay. 04:53.890 --> 04:56.260 That is exactly what I wanted. 04:56.260 --> 05:04.750 Now that I've done that if I so wish I can go back to the U V here and move this area on top of the 05:04.750 --> 05:05.390 other one. 05:05.500 --> 05:09.540 So they share the same data and I'm going to do that right away. 05:09.580 --> 05:18.640 So the select this with snapping turned on was snapping snapping to vertex a move that sits right on 05:18.640 --> 05:19.650 top of the other one. 05:19.810 --> 05:23.800 And that should mean that both sides now share the same normal map. 05:24.040 --> 05:26.770 Hopefully we will see if that works. 05:26.770 --> 05:29.850 So I think I'm done in the image editor for the moment. 05:30.130 --> 05:35.650 Wow that does look interesting that's been mapped funnily but that's absolutely fine because that's 05:35.650 --> 05:37.180 how the other image was mapped. 05:37.180 --> 05:38.030 Not this one. 05:38.260 --> 05:39.850 So that's coming along well. 05:39.970 --> 05:44.200 And what we can do here is go to are you the image editor. 05:44.200 --> 05:46.110 No I want the node editor. 05:46.120 --> 05:48.730 Let's have a look at how it's set up so far. 05:48.730 --> 05:52.300 So we've got the material outputs and the diffuse shader. 05:52.460 --> 05:58.330 Now the diffuse shader has an image defining it which at the moment is this really wacky one and we 05:58.330 --> 06:00.770 want to change it back to the blockwork image in a moment. 06:01.060 --> 06:05.980 And that is being that while it's mapped according to the texture corner of a U V. 06:06.010 --> 06:14.650 Now because we have more than one u v in our scene at the moment I want to make sure that this is more 06:14.650 --> 06:17.560 explicit because at the moment just u v is not enough. 06:17.710 --> 06:22.660 So I'm going to clear and remove it from our scene completely or removed from the node editor completely 06:23.320 --> 06:30.840 and add in an input and if we scroll down we had texture cornet right down at the bottom is you've Emap. 06:31.360 --> 06:32.740 So I'm going to select the movie map. 06:32.750 --> 06:33.210 Um. 06:33.220 --> 06:37.780 To duplicate that because we're going to have one for the normal map and we're going to have one for 06:37.780 --> 06:39.050 the V map. 06:39.370 --> 06:44.050 I'm also going to duplicate the image texture. 06:44.470 --> 06:48.040 So we've got Windows normal here and the chop church block works. 06:48.040 --> 06:53.280 There we go we've got the blockwork back again and I'm going to turn off hello DC for the moment. 06:53.290 --> 06:59.470 I don't need to see it anymore so I'm going to add this movie map to these two here. 07:00.700 --> 07:03.640 Perfect that's exactly what I want see this image. 07:03.640 --> 07:08.070 Texture is being controlled by the normal map so we're going to plug that in. 07:09.410 --> 07:10.910 Won't see anything yet. 07:10.910 --> 07:12.290 It's very tempting of course it has. 07:12.290 --> 07:14.220 Plug them in like vats. 07:14.330 --> 07:17.050 That's going to give us an effect but not the right one. 07:17.060 --> 07:25.270 We need to explicitly convert this into a normal map so let's go to vector and normal map. 07:26.260 --> 07:29.040 And we can plug the colour in to the colour. 07:30.550 --> 07:32.670 And normal in normal. 07:34.980 --> 07:40.380 And there we go it's starting to look much better and we can see there are a few little things that 07:40.380 --> 07:41.580 need tidying up here. 07:41.580 --> 07:42.780 This is horrible. 07:42.780 --> 07:47.410 This line here that doesn't gel with me at all. 07:47.490 --> 07:49.080 Have you got anything else like that. 07:49.080 --> 07:50.890 Not particularly. 07:51.240 --> 07:58.380 Okay so this line here now the question is do we fix it and remake our normal map or can we fix it in 07:58.380 --> 08:03.920 the image editor so let's give a go to the image editor that's zoom in here. 08:04.020 --> 08:08.430 I think we can fix that so I'm going to go right in as close as possible. 08:09.830 --> 08:13.710 And change this to paint mode. 08:14.000 --> 08:16.780 Make that a bit smaller to work with. 08:17.150 --> 08:25.190 Open up the tool shelf and using the colours there the primary colour Im going to pick something purple 08:25.790 --> 08:32.480 and then literally start painting over what we've got here and and make this even smaller go turn accumulate 08:32.540 --> 08:35.310 on so you can go backwards and forwards really quickly. 08:35.450 --> 08:40.470 And as you can see here I am a bit clueless as to how this is going to turn out. 08:40.490 --> 08:42.520 I'm going to assume it's going to come out okay. 08:42.530 --> 08:51.010 I'm going to use the smear now Gia make these bits blend in so it's not so sharp. 08:51.010 --> 08:55.910 Because I'm being careful here not to go over the lines. 08:55.970 --> 09:00.800 I remember as a child shawn's Colour within the lines that they want to break that and the question 09:00.800 --> 09:07.240 is after I save that save it as a window normal that's absolutely fine. 09:10.410 --> 09:15.100 After I save this or I might as well go over that one as well. 09:15.150 --> 09:17.460 So Image save image. 09:17.670 --> 09:18.720 Okay. 09:18.720 --> 09:22.790 The question is does it make a decent impact on here. 09:22.800 --> 09:24.920 The answer is yes it does. 09:24.930 --> 09:25.410 Brilliant. 09:25.410 --> 09:27.230 That looks much much better. 09:27.240 --> 09:30.200 So I'm really happy with that and how that's turned out. 09:30.480 --> 09:32.610 Oh I haven't checked the other side of course. 09:32.610 --> 09:34.460 How does the other side look. 09:36.380 --> 09:39.280 I can't really see the others in the sun. 09:39.470 --> 09:42.530 I'm going to duplicate the sun in this case. 09:43.920 --> 09:48.020 And it doesn't actually matter where it's facing kind of irritates it. 09:48.020 --> 09:51.040 Why 90 right 180. 09:51.330 --> 09:55.490 I'm just going to move this around until you get extra lights. 09:57.080 --> 09:58.880 Let's lock it to the x-axis. 09:58.880 --> 10:00.700 Can we get it on this side as well. 10:01.070 --> 10:02.770 Almost. 10:02.780 --> 10:06.280 So let's see what this looks like on the other side. 10:06.620 --> 10:07.010 Okay. 10:07.010 --> 10:12.200 Yeah that's worked pretty well as well we've got the normal mat being applied across the other side 10:12.740 --> 10:13.790 as well. 10:13.790 --> 10:16.960 It looks a bit odd down here but I will forgive that. 10:16.950 --> 10:18.870 I'm going to make sure that safety. 10:19.130 --> 10:25.340 And of course once I've done that I can hop over into the gothic church and actually see how it's looking 10:25.340 --> 10:28.580 in situ so into the gothic church. 10:28.830 --> 10:30.760 And we've got a couple of windows here. 10:30.770 --> 10:37.080 In fact I think the camera of the last camera of your had yet the switch in rendered mode. 10:41.710 --> 10:48.190 Okay we have a series of them here around the side and I'm going to render that out and see how that 10:48.190 --> 10:48.450 looks. 10:48.450 --> 10:54.400 It's going to take a few moments to do but a rendering is often the best way of seeing how things are 10:54.400 --> 10:55.390 looking. 10:59.120 --> 11:06.530 Okay so this is rendering out one of the first things I can see is a seam joining these together. 11:06.530 --> 11:07.840 It's not that pronounced. 11:07.840 --> 11:11.890 I'm surprised at the I've I've actually given it no consideration. 11:12.750 --> 11:20.970 However some of the more powerful features are standing out quite a lot and that is this area to the 11:21.210 --> 11:26.200 lower left of the window it stands out like a sore thumb and this dark patch here. 11:27.470 --> 11:31.800 It really does stink of repetition essentially now. 11:31.910 --> 11:37.530 I thought this line going down here would be the worst thing completely. 11:37.550 --> 11:40.610 But it turns out that isn't actually the giveaway. 11:40.670 --> 11:48.170 My eye is drawn to this light spots again and again and again and again so that's something I can work 11:48.170 --> 11:48.570 on. 11:49.350 --> 11:54.250 And let's go take a look now and see how it's looking over in a game engine. 11:57.030 --> 12:01.020 Okay so here I am I've not misapplied a texture. 12:01.140 --> 12:04.410 So here I am just walking around in unity. 12:04.410 --> 12:07.620 And we can see that the normal map has applied really well. 12:07.710 --> 12:15.030 Now I did have a few issues trying to get it to actually adhere because it's on the second duvy channel 12:15.030 --> 12:15.860 it doesn't look right. 12:15.860 --> 12:18.880 Unity supports a third TV channel. 12:18.890 --> 12:20.550 I'm open for correction on that. 12:20.550 --> 12:23.220 I'm not a unity expert but here we go. 12:23.220 --> 12:29.690 We've got it a plied to our model and it's looking pretty good considering that is absolutely flat. 12:29.700 --> 12:32.270 That looks like there is detail in the wall. 12:32.400 --> 12:38.130 And again we can see that bright area to the lower left really standing out. 12:38.460 --> 12:44.030 Whether or not we need to do something about that at the moment I'd say no but maybe later on. 12:44.370 --> 12:48.030 How are you guys getting on with your bump maps. 12:48.030 --> 12:53.280 Have you decided that some of your model should be left as just geometry. 12:53.280 --> 12:55.030 Post your results in the discussions. 12:55.050 --> 12:58.480 And as always I will see you in the next lecture.
