WEBVTT 00:00.480 --> 00:02.390 Welcome to the diffuse smap. 00:02.610 --> 00:09.450 In this video you'll create a hand painted texture in the movie image editor and apply it to your models. 00:09.450 --> 00:12.810 Now we've already created an image in the U.S. image editor. 00:12.840 --> 00:15.270 That was great fun playing with those settings. 00:15.270 --> 00:20.410 And now we're going to put those skills to the test that we can actually use on our models. 00:20.460 --> 00:23.340 We'll be creating the diffused map from scratch. 00:23.340 --> 00:26.400 And we'll also be explaining what the diffuse map does. 00:26.400 --> 00:29.120 So before we continue let's start with that last point. 00:29.130 --> 00:30.650 What is a diffuse map. 00:30.870 --> 00:36.780 Well it is the most common map and it's the one most people think of when you say texture. 00:36.780 --> 00:40.890 It defines the colours and patterns on a surface. 00:40.890 --> 00:48.060 Now of course what we could do is build up a loaded geometry and then paint those little bits of geometry 00:48.330 --> 00:53.260 different colours assign different materials to different faces and build it up that way. 00:53.400 --> 00:59.940 So in a way a diffused map is a baking of detail that would be too arduous to do. 00:59.940 --> 01:06.210 In fact we can get away with just painting it ourselves in many cases and we move onto more baking in 01:06.210 --> 01:07.530 a few moments. 01:07.800 --> 01:14.070 So diffused maps in general way they can be challenging to imagine a surface without a light source 01:14.100 --> 01:19.830 or rather with a uniform light obviously without a light source would be completely pitch black. 01:19.830 --> 01:24.840 So you often end up with quite bland looking textures. 01:24.900 --> 01:31.500 Now that isn't a problem because we're going to make sure that the contrast is going to come from a 01:31.500 --> 01:37.200 light source rather than baking it in to our diffuse map. 01:37.260 --> 01:43.680 We're going to avoid creating detail that would usually be generated by bumps on the surface for instance 01:44.040 --> 01:47.740 which means we're going to avoid painting shadows too. 01:47.880 --> 01:52.610 That also means painting light in if we do that and I've said this word a couple of times. 01:52.620 --> 01:55.480 This is called baking into the image. 01:55.590 --> 01:58.760 And we do have to be careful that we dont do that. 01:58.950 --> 02:06.060 If you go ahead and paint shadows and light into our diffuse map that can be great it can be a great 02:06.120 --> 02:07.310 optimization. 02:07.320 --> 02:14.880 However if you plan on changing the lighting in your scene this can cause some discontinuity with the 02:14.880 --> 02:18.960 scene its in to the point that it looks out right. 02:18.960 --> 02:23.620 Wrong because the shadows wont align with where they should be. 02:23.670 --> 02:30.240 How we can use other types of maps specifically normal maps and displacement maps to control the way 02:30.240 --> 02:33.990 that the lighting happens on the surface of our geometry. 02:33.990 --> 02:36.970 Now we're not going to deal with that at the moment. 02:37.010 --> 02:41.480 However we will touch upon those in a few lectures time. 02:41.710 --> 02:46.850 So now let's go ahead and play with a few snaps and hop on over into blender. 02:47.220 --> 02:52.290 Okay so we're back over in blender and the first thing I'm going to do is go work on a basic model and 02:52.290 --> 02:55.700 the best one here is the wall piece that we've been working on. 02:55.860 --> 03:02.310 Now I want to use the existing texture we've got as a kind of a reference for my block work it means 03:02.310 --> 03:08.850 that we can almost apply it straight away to our model without needing to worry how we've got to make 03:08.850 --> 03:10.400 a few tweaks first. 03:10.830 --> 03:16.170 So one of the first things I've noticed and I'm going to have to change this in all my other files that 03:16.170 --> 03:23.910 I have currently saved is that I am leaving the textures packed into the blend file and that's that 03:23.910 --> 03:28.780 might cause me some problems later on when I think they're not packed and they in fact are. 03:28.890 --> 03:36.330 So in this case I'm going to just go to file and external date I'm going to turn off the automatically 03:36.330 --> 03:40.310 pack into blend and then I'm going to save the file also. 03:40.320 --> 03:46.620 Don't forget that I'm going to unpack this image by clicking on the image. 03:46.650 --> 03:51.060 Head to head at this box with a file in it that shows that it's packed clicked at. 03:51.090 --> 03:52.710 Unpack do that. 03:52.900 --> 03:59.190 And I'm going to use the file in original location and that should be absolutely fine use file and that's 03:59.190 --> 03:59.520 fine. 03:59.520 --> 04:03.260 We can go and check the Properties panel now and make sure it's linked to the right place. 04:03.360 --> 04:06.120 That looks absolutely fine to me. 04:06.120 --> 04:08.940 If I click on it I can see it's linked in the right places. 04:08.940 --> 04:13.160 Not really much space there if I expand that we can see that it is there. 04:13.200 --> 04:15.320 Until I run out of space completely anyway. 04:15.420 --> 04:19.290 So now I've got that before I go and overwrite on this image. 04:19.290 --> 04:24.710 I'm going to have to make sure I save a copy and I'm going to call this one. 04:24.940 --> 04:32.190 Well I don't need it in my section assets so I need that in my texture's folder and I notice here it's 04:32.190 --> 04:32.940 called a tiff. 04:32.940 --> 04:42.540 Now I do prefer PND where possible so I'm going to call this church block work and on the left hand 04:42.540 --> 04:48.810 side I'm going to make sure that I switch the savours image where the operator panel would usually be 04:48.810 --> 04:49.640 over here. 04:49.650 --> 04:54.200 I'm going to save it as a p n gene and do I need any compression. 04:54.420 --> 04:56.140 A PRNG is lossless. 04:56.140 --> 04:59.870 I don't think that's going to make too much difference. 05:00.010 --> 05:05.590 Quite honest colour that I am going to go for 16 however and I'm not sure whether I am gonna include 05:05.590 --> 05:06.980 our 4 channel. 05:06.980 --> 05:11.320 So at this point in time with a warm texture Now I'm not going to include an out for Channel. 05:11.420 --> 05:13.860 Some leave it as R G B. 05:14.080 --> 05:15.630 Kate so that's fine. 05:15.640 --> 05:18.100 I'm going to save as image. 05:18.190 --> 05:19.200 That's great. 05:19.210 --> 05:20.590 Can we pick it up from here yet. 05:20.590 --> 05:26.350 No we can't say I'm going to go ahead and open up the image we've just save because that is important 05:26.450 --> 05:29.440 and I will want to start working on the wrong image. 05:29.440 --> 05:32.390 I'm going to go into texture's church block work. 05:32.410 --> 05:33.230 There we go. 05:33.320 --> 05:37.570 Well of course it will look exactly the same but the name will have changed down here and if we open 05:37.570 --> 05:41.390 up the properties window we can see that ends in works. 05:41.390 --> 05:41.890 There we go. 05:41.890 --> 05:43.780 Church block work work. 05:43.850 --> 05:46.300 Looks like I've typed block in twice. 05:46.300 --> 05:48.280 Never mind I can deal with that later. 05:48.610 --> 05:53.970 Okay so now we have that loaded in we can use it as a base to start working with. 05:54.040 --> 05:59.950 But before we do anything else I just need to make sure that the actual texture is being applied over 05:59.950 --> 06:03.240 in the 3D editor so I can see what happens as I update it. 06:03.310 --> 06:08.380 Something will go down to the materials properties down here and because I've already loaded the church 06:08.380 --> 06:09.540 block work. 06:09.550 --> 06:12.450 I can select it there and that switch that one over. 06:12.560 --> 06:19.900 And of course if I wanted it in the blender render I would also need to first of all not use nodes go 06:19.900 --> 06:24.720 over to my texture's and switch it out down here scroll down. 06:24.820 --> 06:26.030 Currently the cinder block. 06:26.020 --> 06:29.020 We changed that over to the church block block. 06:29.260 --> 06:30.770 I like that name up. 06:30.850 --> 06:31.850 I think I'll keep it. 06:31.980 --> 06:39.820 OK so now that we've done that we can go in and I'm just going to get rid of my 3D view for the moment 06:39.850 --> 06:42.470 and just have a closer look at this. 06:42.520 --> 06:46.850 I can use this to basically paint oversoul I've got a right scale. 06:46.900 --> 06:51.760 I'm happy with my blockwork scale as it is at the moment so essentially this I'm not happy with this 06:51.760 --> 06:52.600 particular texture. 06:52.600 --> 06:57.700 It's a great place holder to make sure that the scale in everything else comes out about right. 06:57.820 --> 06:59.580 Something to open up my tool shelf. 07:00.330 --> 07:06.210 Go into painting mode so I can start doing something now before we do anything else. 07:06.210 --> 07:10.210 This texture that we've got at the moment is a tiled texture. 07:10.500 --> 07:18.450 Okay so we want to make sure that anything we do is also tiled and that is a real help especially if 07:18.450 --> 07:20.280 we're putting lots of these together. 07:20.310 --> 07:28.550 If we produce the image and it's untitled or not tiled we will end up with visible shifts in the texture 07:28.560 --> 07:33.930 as it goes from one piece to another and we want to avoid that where possible because the moment we 07:33.930 --> 07:39.480 introduce that it would look rubbish so we need to make sure they're tyred because we're going to have 07:39.480 --> 07:41.200 them next to each other. 07:41.250 --> 07:49.450 Lots Now over on the tool shelf of a bottom one by default is tiling and if we turn on x and y it means 07:49.450 --> 07:54.310 that if we go off of one side of the image we come straight back onto the other. 07:55.000 --> 08:00.420 Pretty effective and we can also from the top and bottom also do the same. 08:01.180 --> 08:02.350 Pretty powerful. 08:02.380 --> 08:07.120 Now if you want to see what this texture is looking like tiled that can be pretty difficult when it's 08:07.120 --> 08:13.040 just a single image in the Properties window we can actually turn on tiling. 08:13.120 --> 08:18.910 So down here under this splice out and get rid of the game properties under display they've got coordinates 08:18.940 --> 08:19.630 and repeat. 08:19.630 --> 08:23.260 If we put a tick in that box we can see it repeating. 08:23.470 --> 08:28.180 The problem with this is we don't know where the edge of the image is anymore because this is a tile 08:28.180 --> 08:33.820 texture is going to look pretty seamless so we can flick in and out of that to see how it's looking 08:33.820 --> 08:35.410 in general as well. 08:35.710 --> 08:41.830 Now this graffiti that are placed on the wall I'm going to undo for the moment and then I'm going to 08:41.830 --> 08:43.520 close the properties panel. 08:43.840 --> 08:48.470 I actually want it so I dont see the repeat and I can start painting. 08:48.670 --> 08:54.320 Now one of the great things with painting obviously by hand you can get a lot of detail in. 08:54.340 --> 08:59.950 However this is a wall so we may want to it depends on the type of wall you go for if you go in for 08:59.950 --> 09:05.290 a bit more jagged blockwork you probably won't need straight lines but if you do want straight straight 09:05.410 --> 09:09.790 lines you're going to have to select a different paint stroke. 09:09.790 --> 09:12.630 So we go down in the tool shelf itself. 09:12.820 --> 09:15.480 We can see paint stroke if we open that up. 09:15.550 --> 09:21.910 We've got a stroke method and dropping down here we've got a series of options now the common ones that 09:21.940 --> 09:27.980 I would use are space occasionally dots and definitely line. 09:28.060 --> 09:32.790 The great thing about line is we can click and drag and we get a reasonably straight line. 09:32.890 --> 09:37.870 The reason why it's bumped up over the top there and down here is because when we went from one side 09:37.870 --> 09:43.080 to the other we actually went on to the other part of the image as you can see as I went down here. 09:43.210 --> 09:48.330 I went onto the top of the next bit which would have been down here or indeed in this corner down here. 09:48.490 --> 09:52.520 So that can be quite confusing at first when you're working with a tiled image. 09:52.600 --> 09:58.270 But now when we put all of these bits together they will be seamless which is very powerful. 09:58.420 --> 10:02.020 Let's just turn the repeat on and we can see that it is pretty seamless. 10:02.020 --> 10:07.840 Now depending on how much detail you've got and how often it's repeated you kind of get that look and 10:07.840 --> 10:11.840 feel especially from a distance that it is a repeated texture over and over. 10:11.920 --> 10:16.060 The big ones here are these darker textures as we have a look at it. 10:16.060 --> 10:20.750 We can see the repeating two blocks here here here here here etc.. 10:20.860 --> 10:22.660 And that really does stand out on my model. 10:22.660 --> 10:28.720 So what I'm going to try and do is make sure that's essentially my brick work is a little more bland 10:29.050 --> 10:30.010 than this one. 10:30.010 --> 10:34.310 And then it sounds an odd thing to do but it's going to make it a bit more uniform the shapes. 10:34.310 --> 10:40.480 However I can make a bit differently and make it a bit more exciting than the squares I think I'm going 10:40.480 --> 10:46.410 to go for a more of an authentic kind of stone type look but I'm going to paint it and see what effects 10:46.420 --> 10:47.290 I can do. 10:47.650 --> 10:51.710 And of course with that I've got a challenge for you guys. 10:51.940 --> 10:55.270 I would like you to paint they basic tile texture. 10:55.270 --> 11:01.800 So start with the wall as it is the simplest piece that we have hand paint a new texture. 11:01.810 --> 11:07.770 Now you can use the a reference image that we've got underneath and base based upon that. 11:07.870 --> 11:13.330 Or of course you can do any other type of texture that you would like but still have that reference 11:13.330 --> 11:18.610 image underneath because if we align it with that then we know it's going to work across our model without 11:18.610 --> 11:22.060 scaling or manipulating our current TV maps. 11:22.060 --> 11:28.570 If you do do something that's that much different you may have to adjust your you v map or create a 11:28.570 --> 11:31.700 new one to match up with your texture. 11:31.750 --> 11:37.690 Do make sure that the texture is tiled and avoid baking in highlights or shadows. 11:37.690 --> 11:40.560 That is important will deal with those later on. 11:40.780 --> 11:43.560 So Boser video now and give that a go. 11:45.820 --> 11:46.450 Okay guys. 11:46.450 --> 11:47.370 Welcome back. 11:47.560 --> 11:51.970 Let's hop back on over into blender and paint a basic tile texture. 11:52.390 --> 11:56.560 Okay so in front of us we have the wall textures. 11:56.560 --> 11:57.950 I'm going to base upon. 11:58.120 --> 12:02.420 I'm just going to see here if I can undo some of those changes brilliant I can. 12:02.470 --> 12:07.170 Now I'm going to go for a slightly different colour going over the top of all this. 12:07.180 --> 12:09.960 First of all I'm just going to block out my lines. 12:09.970 --> 12:16.000 So I'm I've got tiling turned on got a line on there and if we move the cursor over I'm going to use 12:16.000 --> 12:20.430 a mixture of my cursor and my iPad in front of me here. 12:20.470 --> 12:24.610 Now we can see that that is just too big for a line that's going to look ridiculous. 12:24.610 --> 12:30.720 I also need to turn up the strength initially otherwise is going to not do the job. 12:30.850 --> 12:34.450 So I don't know quite how wide are my radius needs to be. 12:34.450 --> 12:40.150 So let's go ahead and work it down to two and see what it's going to be about five. 12:40.150 --> 12:45.120 By the looks of things and that could increase the strength undo those other ones that have just bought 12:45.150 --> 12:46.450 on for testing. 12:46.450 --> 12:50.040 And I'm going to actually use my mouse for this one. 12:50.480 --> 12:51.760 Yeah that's absolutely fine. 12:51.760 --> 12:59.290 So at the moment this is quite a fun task as you can probably see this drawing lines across the screen. 12:59.310 --> 13:02.350 I'm going to go too far because if I get that wrong it will look horrible. 13:02.350 --> 13:04.370 The other side as well. 13:04.660 --> 13:06.900 So let's just make sure it's time. 13:06.920 --> 13:09.240 But it's also lined up. 13:10.330 --> 13:13.750 If we can avoid putting bumps on the side that be great. 13:13.780 --> 13:22.670 Okay so what you do need to be careful is the very edge is very very easy to forget about the edges 13:22.690 --> 13:24.450 like the top edge and the bottom edge. 13:24.490 --> 13:28.000 Otherwise you end up with mega blocks without a line under them. 13:28.000 --> 13:32.710 So I'm going to going to put a line there and you can see that would get a faint one on the bottom as 13:32.710 --> 13:32.960 well. 13:33.100 --> 13:35.300 And the same is true of these vertical lines. 13:35.320 --> 13:39.820 So I'm going to paint these vertical lines and I'll see you back guys back in a few moments. 13:43.200 --> 13:43.730 Okay. 13:43.740 --> 13:45.810 So I think I'm pretty happy with that. 13:45.810 --> 13:50.580 Of course I'm going to quickly hop out and going to repeat and just make sure that's repeating quite 13:50.580 --> 13:51.080 well. 13:51.270 --> 13:51.660 Okay. 13:51.660 --> 13:57.210 I'm happy with that but so I'm going to come out of there and what I'm going to do now is I'm going 13:57.210 --> 14:05.490 to lower the strength to or about there I think I add a little palette and I'm going to call it stone 14:05.490 --> 14:10.990 work for the moment because that is essentially what it is going to be. 14:11.430 --> 14:13.020 So we've got a stonework there. 14:13.050 --> 14:14.930 And now let's go in. 14:14.990 --> 14:20.640 Or I don't know a kind of creamy colour that I quite like that creamy colour I don't have a reference 14:20.670 --> 14:26.220 image on me at the moment to have a look at but I'm going to stick with that for the moment and if I 14:26.220 --> 14:30.040 say for the moment once more you can highlight that for me now. 14:30.120 --> 14:36.060 Is that going to be enough for some of the increase the Phil threshold to one. 14:37.680 --> 14:41.480 Oh no no no no no need to be less than 1. 14:41.580 --> 14:42.800 Go ahead and try that again. 14:42.990 --> 14:44.880 That looks pretty good to me. 14:44.880 --> 14:47.260 That's getting most of the detail. 14:47.280 --> 14:48.880 I want in a. 14:48.900 --> 14:54.930 That's a I don't know what's going on here why won't accept input on there. 14:55.200 --> 14:55.910 It's quite odd. 14:55.920 --> 14:57.170 I can go in and paint it. 14:57.180 --> 14:59.070 That's not a problem at all. 14:59.070 --> 15:06.000 Of course this pixel size is quite small so I'm going to increase it now and keep the strength low and 15:06.000 --> 15:07.920 going to make sure accumulate is turned off. 15:08.020 --> 15:09.090 I want it to build up. 15:09.270 --> 15:10.860 And what size of that brush. 15:10.860 --> 15:11.810 That's pretty big. 15:11.850 --> 15:22.000 I want to go over the image now and make the whole thing just a little bit faded. 15:22.110 --> 15:23.470 I've got it online now. 15:23.490 --> 15:26.520 Oh silly me I completely forgot I had it online. 15:26.520 --> 15:30.390 That's why I wasn't moving this cursor around like a lonely search. 15:30.420 --> 15:33.890 Of course you do need to change your brushstrokes I'm going to go back to space. 15:33.900 --> 15:42.720 Now I should be able to go over the image and calls it these heavy lines to be a bit more faded and 15:42.780 --> 15:48.320 now it's going to hit the F key and make this a bit smaller and do this area in here as well. 15:48.330 --> 15:51.450 Okay so that gives me a rough idea of the guide. 15:51.450 --> 15:58.710 I'm probably going to go over a couple more times and get this looking a bit better. 15:58.710 --> 16:04.350 I'm not not going to go for the square fair I'm just going to use those as a basis and I will see you 16:04.350 --> 16:06.770 guys back in a few moments. 16:09.270 --> 16:17.460 But before I go what I will do here is I'm going to go into the colour picker and go and grab this mortal 16:17.460 --> 16:17.720 line. 16:17.720 --> 16:21.320 I like the colour of that and I'm going to add that is ever so slightly different. 16:21.390 --> 16:27.210 But it will allow me to add the mortar kind of colour that I want into the model when necessary. 16:27.260 --> 16:30.230 I see you guys back again in a few moments. 16:35.430 --> 16:40.480 So I've done a bit of painting now and I just want to see how this texture is actually looking. 16:40.830 --> 16:47.730 I've done the majority of the base sort of laraque and continue adding detail to this with the undulations 16:47.730 --> 16:49.370 of the brickwork for instance. 16:49.380 --> 16:51.450 But that's a good start for us. 16:51.450 --> 16:56.070 Now I'm not using notes I'm guessing that's why I can't see my blockwork. 16:56.340 --> 16:57.180 And there we go. 16:57.180 --> 17:00.120 That is starting to look pretty good. 17:00.120 --> 17:03.900 I think that's much better than the one we had but to begin with. 17:03.940 --> 17:09.540 I'm not happy with some of the lines look a bit wobbly I'm not sure where that one is and I don't like 17:09.540 --> 17:15.330 this one here so there's a few improvements that we can be done but that is coming along reasonably 17:15.330 --> 17:24.780 well and is looking much more church like I suppose rather than knees or breeze block that we had before. 17:24.780 --> 17:26.160 How are you guys getting on. 17:26.160 --> 17:31.410 I hope you spent some time adding a bit more detail than I've got time for here. 17:31.590 --> 17:34.500 Remember to share your brick work what have you come up with. 17:34.500 --> 17:38.810 Have you gone full all of this creamy colour have you gone for a completely different style of block. 17:38.910 --> 17:42.610 Have you gone for different shaped blocks more like some. 17:42.610 --> 17:48.510 I can't think of like stone work where large stones are small stones or put together. 17:48.510 --> 17:53.790 I'd love to see your results please post them in the discussions and I will see you guys in the next 17:53.790 --> 17:54.450 lecture.
