WEBVTT 00:01.170 --> 00:04.330 Welcome to reviewing your work objectively. 00:04.560 --> 00:08.750 In this video we will take an objective look at our model and see what is missing. 00:08.760 --> 00:10.130 Hopefully not too much. 00:10.140 --> 00:13.320 It's just some tweaks that need doing but we'll find out. 00:13.320 --> 00:17.130 So first of all will be any improvements to the modelling itself. 00:17.130 --> 00:21.570 Now modelling is important that we cover this one first because the second one. 00:21.720 --> 00:28.050 Any improvements that need to be made to texturing Well it's reliance on the model itself if we change 00:28.050 --> 00:35.070 the model dramatically the UVB map or change and if the UV map will change well the textures will change 00:35.130 --> 00:35.760 as well. 00:35.760 --> 00:39.010 Or will need to be changed to match the V map. 00:39.180 --> 00:43.510 So that is something that needs to be considered before making any major changes. 00:43.620 --> 00:50.730 If you decide to put in some creases here and there just to accentuate form that's probably not going 00:50.730 --> 00:54.400 to make too much difference to the overall you v map so don't worry about that. 00:54.510 --> 01:01.230 However if we decide to move an eye socket or the nose Well that's going to probably need another U.S. 01:01.240 --> 01:05.420 map creating from it and the texturing update it. 01:05.430 --> 01:08.460 Now finally the lighting and environment. 01:08.460 --> 01:14.050 Now we've got a three point lighting set up at the moment and that is working really well. 01:14.190 --> 01:19.650 However if you wanted to experiment with different lighting which can dramatically change the overall 01:19.650 --> 01:26.190 feel and look of your model remember to take a copy of those lights and then move those around and then 01:26.190 --> 01:32.160 you can switch between those two lighting groups and see the different effects it makes rather than 01:32.160 --> 01:36.350 moving your current lighting and losing the position of it. 01:36.570 --> 01:38.150 And finally the environment. 01:38.250 --> 01:44.510 Well in this particular case we can go with a plane or graduated environment. 01:44.610 --> 01:47.030 I mean I'm going to work with that plinth that we have there. 01:47.160 --> 01:51.320 But to be quite honest we just want the focal point to be our bust. 01:51.360 --> 01:58.050 We do not really want to have a messy environment or at an exaggerated environment's going to be plainsong 01:58.080 --> 02:00.940 and it probably stick with the black background. 02:01.050 --> 02:04.290 Just so the model stands out from it. 02:04.290 --> 02:09.470 So let's go and hop on over into blender and take an objective look at our model. 02:10.800 --> 02:16.550 Okay so I've gone ahead and rendered out my model to see what it's going to look like. 02:16.710 --> 02:23.130 Once we start doing that so once we start getting to the full details and I'm quite happy with the skin 02:23.130 --> 02:26.730 colour and everything but there's something that strikes me. 02:27.060 --> 02:32.340 First of all there's a really harsh shadow down this eye and I don't like that something I have to move 02:32.340 --> 02:33.960 my lighting around slightly. 02:33.960 --> 02:40.530 Perhaps having the main light directly in front of the face and then feel like slightly to the side. 02:40.530 --> 02:43.530 That's that's the first thing I'm going to try in terms of the lighting. 02:43.890 --> 02:45.100 Terms of the modelling. 02:45.240 --> 02:50.110 Well I am pretty happy with the overall model here. 02:50.340 --> 02:55.820 There's nothing that stands out as horrible and there's a little dimple in here but again that's an 02:55.860 --> 02:59.880 under under here that's absolutely fine because skin is not smooth. 03:00.150 --> 03:03.450 And that leads me on to something that's very very glaring. 03:03.480 --> 03:05.490 Is this paint brush working. 03:05.580 --> 03:08.950 Because I'd like to be able to draw on this if possible. 03:09.210 --> 03:15.000 I've got you on soft and at the moment I'm going to go to drawing so I can actually draw what's going 03:15.000 --> 03:16.120 on in my mind. 03:16.140 --> 03:25.410 So these particular highlights I think are about right but they're really telling us a story of how 03:25.410 --> 03:27.480 smooth the skin is. 03:27.480 --> 03:33.690 And certainly this person that I've modelled here in myself I don't have baby soft skin anymore is not 03:33.690 --> 03:38.630 super smooth so the cheek here should have a bit of texture to it. 03:38.900 --> 03:44.520 And I think what's missing from our model is a nice normal map now going in the modelling all those 03:44.520 --> 03:51.030 creases is quite time consuming that's one way that you can do that you can go ahead and model in all 03:51.030 --> 03:56.460 the little dimples and creases and that might actually be the fastest way of getting around this particular 03:56.460 --> 03:56.960 issue. 03:57.000 --> 04:03.170 If there's a texture that um I can apply to the surface and then use a another map like I've done with 04:03.180 --> 04:08.600 the specular map or the glossy map to say where that texture applies and where it doesn't. 04:08.610 --> 04:10.720 That's another way of working it. 04:10.770 --> 04:14.980 Now of course I need to be careful with the node set up and everything else there. 04:15.090 --> 04:18.250 So there are a couple of ways of doing that. 04:18.270 --> 04:23.850 Now whether you go the sculpting route and then baking the Normal's or whether you go the texture route 04:24.180 --> 04:31.390 and then converting it to a bump map or a normal map from there you can get pretty similar results you'll 04:31.410 --> 04:36.570 have more control obviously if you manually sculpt in than if you just use textures. 04:36.600 --> 04:43.170 So there's a time penalty for doing it one way but there's a realism penalty for doing it another. 04:43.410 --> 04:48.290 So it's time now I've had an objective look at this particular model. 04:48.450 --> 04:51.880 Is there anything else before I go on. 04:52.020 --> 04:58.100 Well the lips themselves are quite smooth and lips aren't smooth if you have a look at reference material. 04:58.140 --> 05:00.730 They have lots of fine lines in them. 05:00.780 --> 05:06.240 Certainly there's even I've added freckles here it turns out on the full render they're not coming out 05:06.240 --> 05:06.960 too well. 05:06.960 --> 05:08.530 I mean there's someone for head here. 05:08.610 --> 05:11.310 And to be quite honest they just looked like smudges. 05:11.310 --> 05:14.690 So there's work to be done on that diffusely there as well. 05:14.690 --> 05:20.940 Perhaps just bringing them out that little bit more imp maybe even being a bit more prominent with them. 05:20.940 --> 05:25.940 I was thinking Oh I don't want them so bright badgely we mix everything together like we've done. 05:26.010 --> 05:29.360 They're not quite as prominent as I thought they were going to be. 05:29.610 --> 05:32.600 So it's time for a challenge. 05:32.640 --> 05:39.030 I'd like you to go ahead and assess your model so use reference material I know have said this a lot 05:39.060 --> 05:40.230 but it is important. 05:40.260 --> 05:46.350 If you are unsure or if something doesn't look right you're going to be able to see and compare from 05:46.350 --> 05:52.030 that and take a close look now at the level of getting detail right. 05:52.050 --> 05:58.740 You really do need to see where the skin folds where it changes in texture and how it changes in texture 05:58.740 --> 06:00.150 as well. 06:00.240 --> 06:03.530 Share your work with the community and get their feedback. 06:03.540 --> 06:09.180 We've got a whole course of wonderful people we've got the community site as well that you can just 06:09.180 --> 06:15.450 come to post to staff and ask for feedback and people will gladly give it as well. 06:15.450 --> 06:19.430 Now remember to go ahead and make the changes you want to do. 06:19.440 --> 06:23.850 I know mine at the moment looks more like a plastic doll than it does a human. 06:23.850 --> 06:25.650 And that's because it's too smooth. 06:25.650 --> 06:31.650 That's the major issue I have with my model at the moment so I'll be working on creating a normal map 06:31.940 --> 06:38.120 or certainly a bump map and using a normal node to make the skin more textural. 06:38.400 --> 06:44.650 And remember do one thing at a time and assess the change has it done what you thought it would. 06:44.880 --> 06:49.950 So that's very important if you if you go make 20 changes and it doesn't work out how you wanted it 06:49.950 --> 06:50.590 to. 06:50.820 --> 06:56.040 We don't know which one of those 20 changes might have been the one that caused everything else not 06:56.040 --> 06:59.610 to work the 19 beforehand might have been perfect. 06:59.640 --> 07:02.510 So it very important that you take things one step at a time. 07:02.610 --> 07:09.480 Now as on doing the normal map for instance I'm going to be looking at handing it stage by stage. 07:09.480 --> 07:10.130 I might just. 07:10.210 --> 07:13.500 Do the cheek or the fore head or something along those lines. 07:13.500 --> 07:19.170 Just one area of the face and then seeing if it's made the right effect. 07:19.230 --> 07:23.350 If it has brillion I can get on with the rest of the model as well. 07:23.580 --> 07:26.960 So go ahead pause a video now and give that a go. 07:29.250 --> 07:30.880 Okay guys welcome back. 07:31.050 --> 07:34.460 Let's go ahead and make those changes to the models. 07:35.320 --> 07:41.710 Okay so I've started going through and adding a bit more detail to the inside of the eyes. 07:41.710 --> 07:44.280 I've literally just been sculpting for a while. 07:44.290 --> 07:45.330 Hot Hand then what. 07:45.370 --> 07:47.110 Let's make this fit my screen properly. 07:47.100 --> 07:47.910 There we go. 07:48.100 --> 07:53.840 And then I've also started adding some micro detail to the lips themselves literally. 07:53.860 --> 07:55.200 Again just sculpting. 07:55.300 --> 08:00.880 Well the approach I'm going for here is I believe it's going to be easier to sculpt this detail and 08:00.880 --> 08:07.540 have much more control over it then trying to use textures and masks because I can literally use textures 08:07.540 --> 08:08.990 in a moment. 08:09.050 --> 08:16.060 Well let's do a live example here and hopefully let's save my file before Heidi it is experimentation. 08:16.060 --> 08:20.000 Let's go to the textures themselves and go to a brush mask. 08:19.990 --> 08:25.560 Well let's go to let's say Clay strips and then texture. 08:25.570 --> 08:28.850 Go to the brush or the brush mask it doesn't matter. 08:29.090 --> 08:31.180 Depends which way you want to go about it. 08:31.210 --> 08:35.050 And here the type I'm going to set of or annoy. 08:35.050 --> 08:38.530 Now I don't know what scale this is going to be at the moments and no good. 08:38.530 --> 08:39.870 Let's make sure it's applied. 08:39.870 --> 08:48.160 So in the tool shelf texture Yeah and texture is there and it doesn't look to be working just yet. 08:48.160 --> 08:51.790 Let's try a different one let's try not inflate and deflate. 08:51.790 --> 08:58.270 Let's try all whereas it sculpting draw no texture of air yet that's shoes the foreign texture. 08:58.270 --> 09:01.390 So let's make it a little while let's make this bigger. 09:01.410 --> 09:08.110 Okay so we can see the size of it there is that's going to be quite a skin graft or an alien skin. 09:08.110 --> 09:14.110 So if you'll go in for that type of effect you can and obviously the bigger and more pixellated or the 09:14.400 --> 09:16.540 the chunky that texture is going to be. 09:16.540 --> 09:19.340 So what we need to do here is scale it down now. 09:19.390 --> 09:26.050 I believe there's a scaling here so this is one of these things where you actually increase the size 09:26.050 --> 09:27.240 to make it smaller. 09:27.400 --> 09:30.670 So let's try a hundred and see how that turns out. 09:30.670 --> 09:36.070 Bear in mind that this will change depending on how Zumas you are you mean so something like that will 09:36.070 --> 09:38.510 be completely different to something on those lines. 09:38.710 --> 09:45.070 And that's getting there although the strength of that is far too strong we can see it's really pulled 09:45.550 --> 09:49.290 the skin quites are lots and we don't want that. 09:49.280 --> 09:50.950 So let's zoom out. 09:50.950 --> 09:53.500 Let's try just a little bit higher than that. 09:53.510 --> 09:58.040 Try five hundred five hundred five hundred Okay. 09:58.150 --> 09:59.880 And then finally up here. 09:59.890 --> 10:03.920 Let's lower the strength down to maybe 20 percent. 10:04.270 --> 10:04.720 Okay. 10:04.720 --> 10:06.920 I'm starting to like Fats. 10:07.530 --> 10:08.830 Quite a bit. 10:09.030 --> 10:12.600 And of course you can make things wrinkly. 10:12.630 --> 10:19.100 And then of course smooth out the detail as well if necessary to make it not so wrinkly in place. 10:19.130 --> 10:25.830 It's a case of us actually working out relatively well obviously resumes and but we get the whole face 10:26.130 --> 10:31.320 looking very horrible would happen to me if I stayed in the sun for too long. 10:31.320 --> 10:34.330 So obviously you can go for an extreme effect like this. 10:34.440 --> 10:40.080 And in fact whilst we see this extreme effects I'm going to go ahead now because we're actually altering 10:40.080 --> 10:42.330 the model I don't need to bake this into a texture. 10:42.330 --> 10:46.980 Obviously if you were now exporting this you would take this as a normal texture. 10:47.070 --> 10:52.920 So you it can be reapplied to a low poly model but since we actually have a well it basically alive 10:52.950 --> 10:58.740 and ready to go under the rendering settings because under render under the vomity rez it's also air 10:58.740 --> 11:00.890 force so we get the full benefits. 11:00.960 --> 11:06.660 Let's just have 12 and see what that ends up looking like and I'll see you guys back once this is rendered 11:06.660 --> 11:07.100 out. 11:08.540 --> 11:13.140 So as expected it has had a relatively extreme result. 11:13.250 --> 11:15.550 We just saw my windows out here. 11:15.890 --> 11:17.900 Let's bring this one across. 11:17.900 --> 11:18.380 Can I do that. 11:18.380 --> 11:18.620 Yeah. 11:18.620 --> 11:19.480 There we go. 11:19.490 --> 11:24.360 So we've got a relatively textured surface to a model now. 11:24.410 --> 11:27.430 In fact it's been so extremely in places with that taste. 11:27.440 --> 11:35.810 You can see by its casting quite a deep shadow on are particular mesh has also taken a while to render 11:35.810 --> 11:41.540 that took nearly six minutes to render So this is where doing the sculpting and working out and perhaps 11:41.540 --> 11:43.570 making a normal mat from it. 11:43.610 --> 11:49.130 We should see a render time improvement because it's not having to handle all of the geometry. 11:49.130 --> 11:56.120 So in this particular scene itself there's one point four million trying goals which is quite a bit 11:56.130 --> 12:04.070 there's 700000 births he so as to render all of those out the less vs. It has to do the better and having 12:04.070 --> 12:05.420 a look at the lips. 12:05.600 --> 12:06.820 I'm quite happy with those. 12:06.820 --> 12:13.340 They've got the the right texture obviously they've been hammered by my silly use of this particular 12:13.340 --> 12:17.790 texture brush but otherwise I'm really happy with how the lips turned out. 12:17.900 --> 12:25.250 So it's time to work a bit more delicately with these particular wrinkles and folds in the skin. 12:25.370 --> 12:29.710 Well I'm going to go off and do that now and I'll see you guys back in a few moments. 12:31.630 --> 12:35.790 Okay so this is the render how it stands at the moment. 12:35.830 --> 12:41.980 It's not a complete render and there's still some further diffused texturing to add in I haven't added 12:41.990 --> 12:45.580 in my wrinkles yet but I have fleshed out my face. 12:45.820 --> 12:48.640 So it's a lot more representative of me. 12:48.670 --> 12:49.540 In this case. 12:49.700 --> 12:55.780 So I noticed when looking from the front if I move round my model here and certainly just put it into 12:55.810 --> 12:57.680 orthographic projection. 12:58.120 --> 13:03.520 My ears dont stick out quite as far from my face as they do normally. 13:03.720 --> 13:09.170 I I have made them in fact so I have had to puff out my cheeks a little as you can see here I've added 13:09.190 --> 13:10.480 in my little double chin. 13:10.480 --> 13:13.650 Well if you're doing something realistic you might as well get there. 13:13.990 --> 13:14.810 So there's just a few. 13:14.800 --> 13:19.480 I'm happy with all the indentations that I haven't made it in my face. 13:19.510 --> 13:25.570 There's a little bit skin texturing to do in terms of the gloss map I just need to refine that where 13:25.570 --> 13:27.470 things are glossy and where things are not. 13:27.490 --> 13:33.550 And another thing that I have done and I almost forgot about when setting up my nodes is that skin is 13:33.550 --> 13:41.100 also translucent so I just take you to my node set up as it is at the moment so we've got these layers. 13:41.110 --> 13:47.140 If we think about them and how much of them come through starting with the deepest layer of the skin 13:47.140 --> 13:57.280 and working up and as we go down this list I have added in a translucent B s the f shader which is also 13:57.280 --> 14:01.960 using the same colour the base colour in the model. 14:01.960 --> 14:08.730 And if we just isolate that self the translucent slits isolate that we see that with the colouring there 14:08.740 --> 14:14.560 it makes it obviously much better than if it is just a plain old white but with the colour there we 14:14.560 --> 14:20.680 can actually see it adds translucency to the areas that need it and when that's mixed in with everything 14:20.680 --> 14:24.250 else that gives a slightly more realistic feeling. 14:24.250 --> 14:30.530 If you don't have the translucency in your model you lack that one fundamental thing about skin. 14:30.700 --> 14:36.160 And that's the fact that it is translucence you need to make sure you tell blender or certainly in the 14:36.160 --> 14:38.460 nodes that is translucent. 14:38.500 --> 14:44.230 So I've done that here and I'm very happy with that so the final thing to do for me at the moment is 14:44.230 --> 14:49.360 just to work on the diffuse textures so I start getting some of the freckles that are through and just 14:49.360 --> 14:54.040 bumping up where things are slightly shiny and where they're not because that's not coming through quite 14:54.040 --> 14:56.040 as well as I'd want it to. 14:56.490 --> 14:59.080 And I'll see you guys back in a few moments. 14:59.200 --> 15:08.020 Okay so after some final tweaks and rendering this is what I'm going to class as my final mesh for the 15:08.020 --> 15:10.370 moment and final textures. 15:10.400 --> 15:15.910 I've worked out what was going on with the gloss shader just in have the right one attached. 15:16.030 --> 15:19.860 For some reason during my creation I had Let's just see here. 15:20.020 --> 15:26.730 I had a head glossy which was just blank and his glossy PRNG and only that one was applying the Course. 15:26.740 --> 15:29.260 Black will mean that that's not there. 15:29.260 --> 15:30.930 So that's why that was missing. 15:30.970 --> 15:36.220 No matter what I tried that should disappear now it's not being used on anything after I've saved and 15:36.220 --> 15:37.140 reopen. 15:37.420 --> 15:42.380 Let's have a quick look at the no set up anything else that I've added since we've last seen. 15:42.520 --> 15:46.470 We've got this bit here we've got the translucency that I've added in. 15:46.480 --> 15:47.590 That's absolutely fine. 15:47.590 --> 15:50.410 What I have done is art the image texture itself. 15:50.410 --> 15:57.610 I've used a hue saturation and value just to tweak my mesh ever so slightly to see if we can see it 15:57.670 --> 15:59.240 in action. 15:59.730 --> 16:01.570 Okay so the bass is here. 16:01.570 --> 16:07.000 Now I've just boosted the colours slightly and given it a slightly more yellow cast to it. 16:07.000 --> 16:10.110 I mean I could boost that up even more to maybe one point. 16:10.110 --> 16:16.320 So if you go to high of course you just look sunburnt as it goes up to a maximum of two. 16:16.330 --> 16:21.750 There are maybe and stretch to 144 and have slightly darkened the model as well. 16:21.760 --> 16:24.570 It was slightly too light. 16:24.970 --> 16:31.890 Okay so after doing those the next thing that I did was I literally plugged in a very annoyed texture. 16:32.860 --> 16:39.630 And made it with a bump note and then plug it into the diffuse the translucent and the glossy notes 16:40.080 --> 16:47.700 and then that gave us a very little bumpy surface across the entire model itself giving us a slightly 16:47.700 --> 16:48.630 textured feel. 16:48.750 --> 16:55.410 But it's never that strong so it's not really seen across the model because we don't colour we want 16:55.410 --> 16:56.700 the the factor there. 16:56.700 --> 17:01.270 So it's is is kind of one of those things that's not seen but is seen. 17:01.380 --> 17:06.050 So you won't see it directly but it does have an impact on the render. 17:06.090 --> 17:10.490 I tried different scales I found that thousands seemed to work for my particular model. 17:10.500 --> 17:13.610 One is obviously you can be big and blocky and won't work at. 17:13.710 --> 17:17.460 And why aren't we seeing it at the moment. 17:18.740 --> 17:24.670 Be a preview that for an I text ulrich's in to almost every went into rendered mode. 17:24.720 --> 17:31.890 Let's boost that up so I tried 10 and obviously it out then work till it tried a thousand and found 17:31.890 --> 17:37.440 that when I zoomed in that gave me the right sort of level of detail around the thousand mark pumped 17:37.440 --> 17:42.440 into the bump and obviously I wanted to make sure here that it wasn't too strong. 17:42.450 --> 17:44.400 I had to play several times. 17:44.670 --> 17:49.320 Checked out the glossy individually because I saw one that would really sparked off and that's a nice 17:49.320 --> 17:51.660 little textured feel across there. 17:51.660 --> 17:57.860 I didn't map that at all I found that once everything was all plugged in it worked rather well. 17:57.870 --> 17:58.340 Brilliant. 17:58.440 --> 18:01.800 Well how did you guys get on How's your head coming along. 18:01.800 --> 18:07.950 As just a few final things that are obviously missing from this model but we can sort those out in good 18:07.950 --> 18:08.880 time. 18:08.880 --> 18:11.010 Of course I'd love to see how are you getting answered. 18:11.010 --> 18:13.150 Do remember to share your work. 18:13.290 --> 18:17.780 And of course as always I will see you guys in the next lecture.
