WEBVTT 00:01.140 --> 00:07.010 Okay so we are almost there where we can start actually making stuff in blender. 00:07.170 --> 00:10.260 But there's a couple of things that we have to do first. 00:10.290 --> 00:12.510 The first one is a level of detail. 00:12.510 --> 00:18.450 So welcome to level of detail or Lord elodie as its abbreviation. 00:18.570 --> 00:23.610 Now in this video you focus on representations of the right size and shape. 00:23.760 --> 00:26.490 But just a block worked models. 00:26.520 --> 00:32.990 That's very important because that allows a week iteration of your models. 00:33.000 --> 00:38.680 Remember higher detail often requires more processing time too. 00:38.730 --> 00:45.220 So not only do you have to input more time but there are more vertices to be calculated in a scene. 00:45.330 --> 00:50.160 The actual rendering time later on will take longer as well. 00:50.160 --> 00:53.410 So Lord at numbers and letters. 00:53.430 --> 00:59.370 Well we get a lot numbers are quite a common thing and they range from the highest detail Lodz zero 00:59.520 --> 01:03.390 or the base meche and it goes up in numbers. 01:05.860 --> 01:11.180 Solod ZERO often refers to the highest detail model sometimes called the base model. 01:11.350 --> 01:16.140 Now to avoid confusion with this we are going to use letters. 01:16.290 --> 01:22.210 Okay now bear with me on this it will become clearer as we go because we are starting and being nice 01:22.210 --> 01:24.780 and lean with low poly box models. 01:24.910 --> 01:31.270 We don't know what the highest level of detail model we're going to create is at the moment. 01:31.270 --> 01:41.910 So the letter aiza elodie and he represents the lowest polygon model with b c d etc. increasing in detail. 01:41.920 --> 01:48.700 Now you do have to watch a time versus your level of detail so the level of detail and time are usually 01:48.700 --> 01:50.560 directly proportional to one another. 01:50.560 --> 01:56.770 The more detail contained within your model it's likely it's taking you longer to produce that model 01:56.830 --> 02:03.520 in the first place now when fleshing out a seam and prototyping you probably want quite a few assets 02:03.580 --> 02:10.780 and you want to do that quickly and you can test models in you and your scene when you set things up 02:10.990 --> 02:13.540 nice and quickly that is very important. 02:13.540 --> 02:20.000 We don't want to get bogged down creating an assets that may never be used in a scene or we don't like. 02:20.020 --> 02:25.200 So you decided to make a bench in the church or at home if you decided to make a sofa. 02:25.390 --> 02:28.450 Well you can test the model and make sure it fits properly. 02:28.570 --> 02:31.220 Let's say let's take a sofa for a quick example. 02:31.300 --> 02:35.590 If we decide to well I want a three seat sofa rather than a two seat sofa. 02:35.830 --> 02:42.100 Well if you've already spent all that time modelling a two seats over you might be able to expand it 02:42.100 --> 02:43.190 and work around it. 02:43.300 --> 02:50.050 But if you put it into your scene in the first place a low poly representation of it and then decided 02:50.110 --> 02:56.620 Well no I want the three you can do that really quickly without having binning your your asset that 02:56.620 --> 02:57.970 you've created. 02:58.150 --> 03:04.930 And of course binning the time that you've used to create that now lower level of detail versus the 03:04.930 --> 03:06.380 time taken example. 03:06.390 --> 03:13.080 Now these are only rough guidelines don't take these accurately because some models can vary significantly. 03:13.210 --> 03:20.290 But what is important when we're talking about the polygon level here is that we are each polygon is 03:20.350 --> 03:21.930 actually doing something. 03:21.940 --> 03:23.650 It's not wasted. 03:24.290 --> 03:25.700 Geometry. 03:25.700 --> 03:27.210 So we got levels. 03:27.230 --> 03:28.530 ABC indeed etc.. 03:28.550 --> 03:34.230 An example here of around two hundred two thousand twenty thousand and two hundred thousand polygons. 03:34.250 --> 03:39.160 Now the time taken again this is approximately will depend on the model but you will find that you can 03:39.170 --> 03:45.090 you can mock-up something very quickly that's our block model and is just a representation of the item 03:45.090 --> 03:50.630 the right size and shape in around 30 minutes or so maybe less if it's a more simple one or maybe a 03:50.630 --> 03:51.340 little more. 03:51.340 --> 03:57.380 If it's a little more complex and from that you can start to derive more and more detail. 03:57.410 --> 04:01.150 So a slightly more detailed one may take you a couple of hours. 04:01.190 --> 04:04.610 Highly detailed one may take you a whole day to work. 04:04.760 --> 04:10.970 And then finally of course we can all spend weeks on a project but we need to make sure that if we ever 04:10.970 --> 04:17.600 go up to Certainly the level C and that we need at that level of detail you may find that you're going 04:17.600 --> 04:23.750 to create something that sits at the back of a room that's far away from your camera angle and therefore 04:23.750 --> 04:26.240 never needs to be that detailed. 04:27.330 --> 04:34.190 So each polygon counts in this example and the time taken includes other art work. 04:34.320 --> 04:41.820 That is very important because if we don't have the time included to make the other art work we're just 04:41.820 --> 04:45.690 talking about meshes now on the basic level of detail. 04:45.690 --> 04:50.690 It is unlikely going to have anything else but maybe a base colour. 04:50.820 --> 04:55.890 So your model very rarely would you add textures and things like that all on at that level. 04:55.890 --> 05:01.830 Once you go up to B.C. you're going to start to want to make normal maps diffuse maps will go into those 05:01.830 --> 05:04.900 in much more detail later on in this section. 05:05.700 --> 05:07.850 Okay guys so it's Challenge time. 05:07.860 --> 05:09.750 I'd like you to list your models now. 05:09.780 --> 05:15.310 You already have a series of assets that you want to create so we can refer to that list. 05:15.390 --> 05:17.660 But we need to bulk it out a little more. 05:17.820 --> 05:20.380 So what assets do you need. 05:20.410 --> 05:25.630 That's very important because that is different from what assets do you want. 05:25.650 --> 05:33.480 So if you were making a room the walls are a necessity a certain item in the room a small object is 05:33.480 --> 05:39.740 something you may want in a scene to add a bit more detail to add a bit more nuance to the scene. 05:40.230 --> 05:43.650 Now which assets will help bring life to your scene. 05:44.680 --> 05:52.390 What's in the room that you're creating That's gone that add to make it look lived in or used. 05:52.420 --> 05:54.910 Remember at this point we really all a break. 05:54.910 --> 05:58.510 Complex models down into components. 05:58.510 --> 06:03.180 This is both for easy a building and modification. 06:03.190 --> 06:09.070 So go ahead pause of the year now and go through and think carefully about what you're going to put 06:09.130 --> 06:10.500 into your scene. 06:13.380 --> 06:14.030 Okay guys. 06:14.040 --> 06:15.000 Welcome back. 06:15.000 --> 06:20.730 Well I'm going to go through my scene now that I'm creating and think about carefully what I need in 06:20.730 --> 06:23.120 my scene what I wanted my scene. 06:23.160 --> 06:28.070 Anything extra That's going to help bring a bit more life to the scene itself. 06:28.200 --> 06:33.990 Whether or not I've got a few ideas in my mind of course this is the ideal time is where we want to 06:33.990 --> 06:40.650 be nice and quick so we can model things and get the idea coming to life. 06:40.680 --> 06:46.410 And finally I'll be having a look at what is complex and actually can be broken down into components 06:46.670 --> 06:51.290 so it is easier to build easier to modify and in general work with. 06:51.690 --> 06:57.530 Okay so back over to that trillo board that I was working with earlier I've removed that duplicate old 06:57.530 --> 07:01.920 profile of a bit cheating her having Where least it was down to 10 anyway. 07:01.980 --> 07:08.330 So I've broken my first four into what I need and what I would like to have in my scene. 07:08.460 --> 07:11.150 So it wouldn't be a church without an altar in it. 07:11.160 --> 07:13.180 I certainly need some blank walls. 07:13.350 --> 07:19.800 In fact the blank wall was the wall the window the large windows and the archways et cetera can all 07:19.800 --> 07:22.340 be classed as structural items. 07:22.470 --> 07:25.410 So I've done a bit of colour coding here and um I'm halfway through. 07:25.410 --> 07:33.270 This is how I'm managing my project here as such I'm using the cello and I'm using some colours so the 07:33.270 --> 07:35.370 blank wall is actually part of a modular. 07:36.000 --> 07:41.850 And I've got some labels here now I'm going to explain to you my thinking behind this so I don't know 07:41.850 --> 07:47.670 actually what the end item will be but I'm taking a guess at the moment as to what level of detail I'll 07:47.670 --> 07:51.480 be going to with these particular items. 07:51.480 --> 07:58.530 So in this case a blank wall I'm figuring is going to be pretty low detail it's at worst it's probably 07:58.530 --> 08:02.990 going to be a one two three four five six seven eight it's going to be a stretch. 08:03.270 --> 08:09.180 Basically it's also part of a component modular is actually part of the building now I could build the 08:09.180 --> 08:16.200 building as one big mesh but that would create problems further down the line if I needed to alter something. 08:16.230 --> 08:20.460 I'm a bit stuck at least if I've made it out of components. 08:20.460 --> 08:25.480 It's much easier it's old song about Add a component and moduli it into that. 08:25.650 --> 08:30.510 And the same with the larger windows I'm going to make those surveys slots in with the building. 08:30.510 --> 08:37.470 Now that I can imagine the large windows requiring a high level of detail because they are going to 08:37.470 --> 08:44.280 be one of the perhaps one of the focal points as I'm looking down the church towards those large windows 08:44.280 --> 08:46.110 that tend to exist at the end. 08:46.110 --> 08:50.030 I'm probably going to want some high detail in them so they look awesome. 08:50.160 --> 08:52.360 Otherwise I would lose out on that. 08:52.470 --> 08:57.060 And again it's that component and modular and we can go down and we can see what's come here that the 08:57.060 --> 09:01.480 floor tiles I may vary them from area to area archways again. 09:01.500 --> 09:06.060 They're actually part of the building structure so lots of these things as you can see are modular and 09:06.060 --> 09:08.100 I can put them all together. 09:08.340 --> 09:15.390 Now unsurprisingly the things that give the scene the most life and vibrance are probably things I want 09:15.390 --> 09:18.890 to have in the scene not necessarily need at this point. 09:18.900 --> 09:23.420 We cannot construct this building without some fundamental building blocks. 09:23.430 --> 09:30.090 However there are certain things I would like to add in later in things like her carpet or a rug on 09:30.090 --> 09:36.480 the floor mats some candles of course if you making another interior you might go well I've got a desk 09:36.480 --> 09:40.700 in the room but there's nothing on the desk perhaps I need a pot in there over it. 09:40.740 --> 09:46.890 If you're modelling a kitchen Well you can make it look really stark but real kitchens have lots of 09:46.890 --> 09:51.690 clutter in them and those are things that models that you probably want to have in your scene but not 09:51.990 --> 09:57.570 necessarily need at the moment to get the general layout feel so it's important to make that distinction 09:57.840 --> 09:59.670 at this point in time. 09:59.670 --> 10:06.240 Now there are a couple of things that I've also thought about a long distance away so I'm thinking not 10:06.240 --> 10:07.040 sure at the moment. 10:07.060 --> 10:12.330 I'm only going to be wanting to look from probably the batla Church to the front or the front to the 10:12.330 --> 10:12.690 back. 10:12.690 --> 10:17.670 I'm not sure which way round these things are towards the altar basically looking from the doorway of 10:17.670 --> 10:21.130 your major one long corridor like I drew earlier. 10:21.210 --> 10:24.210 Now the altar itself is going to be low. 10:24.210 --> 10:28.340 Detail doesn't have to be high detail because we're going nowhere near it. 10:28.530 --> 10:30.170 So that's why it's only a medium. 10:30.170 --> 10:31.440 And then the ceiling. 10:31.440 --> 10:34.620 I'm not actually sure if we're ever going to see the ceiling. 10:34.620 --> 10:40.650 So there is a case point to not modelling at all but you can put it in there's a low poly model and 10:40.650 --> 10:44.230 that's probably as far as we're going to take it. 10:44.250 --> 10:47.610 How did you guys get on how did you structure your scene. 10:47.610 --> 10:50.310 Did you come out thinking well hang on a minute. 10:50.310 --> 10:53.470 There are tons of models I want and only a few that I need. 10:53.520 --> 10:58.660 Often I can have filled this model list up with tons and tons of other items. 10:58.770 --> 11:06.690 But it is important to help focus on what you really need for your scene to work how a prototype is. 11:06.810 --> 11:12.790 You don't want to be going ahead and modelling tiny items in your scene when you've not even get. 11:13.100 --> 11:19.340 The fourth thing laid out yet so please share what you've come up with in the discussions and I will 11:19.340 --> 11:21.790 see you guys in the next lecture.
