WEBVTT 00:00.460 --> 00:04.400 A guy's welcome to problem solving in this video. 00:04.400 --> 00:08.640 You will realize that starting again is sometimes the best option. 00:08.700 --> 00:10.910 So a little background story here. 00:10.910 --> 00:13.790 I was busy reorganizing my parts. 00:13.800 --> 00:20.010 I accidentally did something and the whole scene just fell apart on me. 00:20.250 --> 00:26.490 And I had a choice at that point do I try and fix the problem or do I just put all the pieces back together 00:26.490 --> 00:27.010 again. 00:27.330 --> 00:38.010 It turns out that after I made my changes to my nave that I had a problem with the scale and position 00:38.010 --> 00:41.550 of a lot of the other bits of my model. 00:41.550 --> 00:48.480 So in essence starting again was actually the best option because trying to move everything else subtly 00:48.480 --> 00:51.200 in between was just not an option. 00:51.240 --> 00:56.830 So we're going to see that even the well prepared scenes can be broken by subtle changes. 00:57.150 --> 01:03.580 Now we're going to get help with problems that you may have run into when making your building as well. 01:03.600 --> 01:11.370 So what we'll do now is hop on over into a blender and just go through some of the annoyances that I 01:11.370 --> 01:15.950 had during the construction of my building especially with modular parts. 01:16.110 --> 01:22.860 There won't be a specific challenge in this section but I would like you to share the challenges and 01:22.860 --> 01:29.370 production methods that you've gone through so we can all share our group knowledge and help each other 01:29.370 --> 01:34.630 out when it comes to constructing more complex items from individual parts. 01:34.740 --> 01:36.970 So let's hop over into a blender. 01:37.720 --> 01:43.960 Okay so I have started a brand new blender far here and reimported all of my pieces. 01:44.110 --> 01:50.410 What happened that made it go horribly horribly wrong is that at some point during the construction 01:50.410 --> 01:57.460 I had hopped into edit mode on my pieces and the origins had moved and the alignment was no longer working 01:57.760 --> 01:59.030 as it should have done. 01:59.080 --> 02:05.920 And when you hop in to edit mode and move your piece you're moving it in it's own local space which 02:05.920 --> 02:11.620 of course means that when you hop out of edit mode all of the other pieces that are linked to that one 02:11.680 --> 02:17.980 also move and your whole scene falls apart rather than trying to fix that problem. 02:17.980 --> 02:24.310 I'm going to build myself a new church with my new pieces and put it all together whilst we're thinking 02:24.310 --> 02:26.110 about how it's constructed. 02:26.110 --> 02:31.180 One of the things we need to take into account is how the pieces actually interact. 02:31.180 --> 02:37.540 You can see here yes they are still only linked models haven't made them proxy yet but we can see where 02:37.540 --> 02:40.210 the corner piece intersects with these other pieces. 02:40.210 --> 02:42.160 We've got a graphical glitch going on. 02:42.160 --> 02:48.370 Now one of the ways of making sure that you avoid graphical glitches like the one in front of us and 02:48.370 --> 02:55.330 tiling problems in general is to either create parts as a whole which is difficult because I like the 02:55.330 --> 02:57.180 idea of having modular. 02:58.200 --> 03:01.680 One of the other things we can do is force the issue. 03:01.890 --> 03:08.050 And what I mean by that is making this corner piece an action bigger slightly. 03:08.060 --> 03:15.790 Then the pieces joined to and that introduces a natural break in the image in the actual geometry itself. 03:15.900 --> 03:21.930 And we don't end up with any overlapping which means if we do need to push apart inside another part 03:21.930 --> 03:26.720 for whatever reason that it's not going to cause a graphical corruption. 03:26.880 --> 03:32.340 So for instance this one here has this funny hash here some scanner save the file that I'm working on 03:33.180 --> 03:36.850 now in the corner pieces of I got a short cut to it. 03:36.850 --> 03:37.710 No I haven't. 03:37.710 --> 03:40.920 Let's go to the corner. 03:41.010 --> 03:42.880 What I can do here. 03:43.920 --> 03:50.000 Is hop into edit mode and actually pull these faces out slightly. 03:50.400 --> 03:52.670 So I'm going to extrude. 03:53.600 --> 04:01.390 I want both of those faces and group strood here by point one doesn't have to be much. 04:01.460 --> 04:06.440 Now this is speculation of how it's going to look but I'm going to be mean about it and try to extrude 04:07.070 --> 04:09.690 this way by point one. 04:10.350 --> 04:14.550 Okay so now the kormos ever so slightly bigger than anything that surrounds it. 04:14.570 --> 04:18.140 I haven't changed the origin or anything else of this model. 04:18.140 --> 04:18.900 Hop out. 04:18.920 --> 04:20.820 That looks okay so far. 04:21.020 --> 04:23.100 And let's go ahead and save it. 04:23.330 --> 04:30.770 Now when we hop back in to our Gothic church in new we see that it's all somatically creates this little 04:30.770 --> 04:31.490 ridge. 04:31.520 --> 04:35.930 Now I can see straight away of it matched up in that way it's going to ruin the door because we got 04:35.930 --> 04:38.670 the door in the window on top of one another there. 04:38.960 --> 04:45.110 But this piece itself is now if we push another bit of geometry into it like a plain wall piece is not 04:45.110 --> 04:48.590 don't complain at least not on this side. 04:48.830 --> 04:53.660 Now we've got to think about the other side which is also going to have some graphical corruption. 04:53.850 --> 05:00.350 Of course we want to make these changes subtle and not make them so they stand out too much. 05:00.350 --> 05:07.610 So one of the other things we can do here and it will vary from model to model is opening up our corner 05:07.610 --> 05:15.340 piece again this is one of our structural pieces is actually taper these outer edges in. 05:15.530 --> 05:16.100 So it's. 05:16.130 --> 05:20.400 So there will be a slight warp in me in the surface itself. 05:20.480 --> 05:30.840 So if we grab this edge here and we're snapping turned on let's and merge vertices turn on and all. 05:31.070 --> 05:38.750 If we snap to a vertex I should be able to bring it all the way in and then that will look like that 05:38.750 --> 05:39.380 from the top. 05:39.380 --> 05:45.680 This is its profile and I'm hoping that's going to look at and again this is all about lean production 05:45.680 --> 05:47.150 We've spotted a problem. 05:47.270 --> 05:51.660 We're going to try and fix it in creative ways or useful ways. 05:51.710 --> 05:54.920 So we've also got the issue on the inside as well. 05:54.940 --> 06:03.950 Now I am going to grab the face here extrude by point one I'm using Point one here as an example it 06:03.950 --> 06:05.640 doesn't have to be of course. 06:05.810 --> 06:14.400 And I'm going to push that corner back into itself so I'm going to move it to there and do the same. 06:14.420 --> 06:22.160 This face here in the extrude it will have hit by mistake and then extrude it by point one and then 06:22.190 --> 06:26.000 push this edge that we can't see if I can select it even through a model. 06:26.000 --> 06:31.810 Note the Happer hop a wire frame to do that and then try and get the right one so that one there. 06:32.250 --> 06:37.140 All this is this is more tricky when you've got it are going to have to do the whole operation in wire 06:37.160 --> 06:41.080 framed so that sume in here and see if we can find the right one. 06:41.190 --> 06:43.780 We're going to move it to that point there. 06:43.940 --> 06:48.820 Okay so now let's have a look around our model in object mode. 06:48.830 --> 06:52.900 It looks okay looks slightly wonky from the top but that's okay. 06:52.970 --> 06:59.750 It will be slightly one key and that should help us when it comes to corner pieces. 06:59.750 --> 07:04.310 Now I don't know how it's going to look it might look absolutely atrocious in which case back to the 07:04.310 --> 07:10.730 design board and we'll remodify it but this will stop me having too many artefacts. 07:10.730 --> 07:16.860 Of course if I push something in into this model so I want a shorter corner piece. 07:16.930 --> 07:22.880 The issue will still be there be there that there will be a tiny ridge here so that doesn't quite solve 07:22.880 --> 07:23.450 that issue. 07:23.450 --> 07:29.270 So anyway enough of me speculating let's see what it's like in action. 07:29.270 --> 07:32.670 So back into here and that looks fine from the outside. 07:33.890 --> 07:36.030 And looks fine from the inside as well. 07:36.050 --> 07:42.620 It's no longer going on top of one another in fact that way it looks like I've skewed it the wrong way. 07:42.620 --> 07:47.570 I wasn't thinking Oh no this is why hopping backwards and forwards is very powerful. 07:47.570 --> 07:49.610 I've put a lip in when I didn't want to let. 07:49.610 --> 07:51.350 I've moved them in the wrong way. 07:51.440 --> 07:53.370 Silly my silly silly silly. 07:53.390 --> 07:58.730 So of course we can go back and correct that and I'll go and do that now and then I'm going to reconstruct 07:58.790 --> 08:06.500 my model because of the fatal error I did earlier where I moved one of these in edit mode and it caused 08:06.590 --> 08:12.220 the whole scene to fall apart i literally destroyed my church in a few clicks. 08:13.070 --> 08:18.010 The other thing that changed the fundamental design of the church was the vault itself. 08:18.010 --> 08:23.980 I didn't realise quite how this would modify the scene that I'm working on. 08:24.050 --> 08:27.200 As you can see here it's slightly wider than the other one. 08:27.200 --> 08:29.980 This is where the pillars of the church are going to be sat. 08:30.200 --> 08:36.500 And because of the width of it's changing ever so slightly it cause the rest of the model to need to 08:36.500 --> 08:43.010 be have a rebuild anyway compounded with the problem that I created last pose I created the vault as 08:43.010 --> 08:43.290 well. 08:43.340 --> 08:47.990 But compounded with that problem it's going to be far quicker to just reconstruct my church in a very 08:47.990 --> 08:50.160 similar manner to how it was before. 08:51.050 --> 08:52.090 So welcome back. 08:52.250 --> 08:57.500 And I'm in the middle of constructing my tower piece at the moment I just want to show you a really 08:57.500 --> 09:02.230 quick way probably already know about this but might not be doing it. 09:02.300 --> 09:09.600 So I'm going to hold down g and Z and then hold down Shift and move that up to a micro blender unit 09:09.600 --> 09:16.520 so then point ten of a blender unit and I'm going to duplicate this again and move it up on the said 09:16.520 --> 09:23.870 axis and then up another two and obviously I'm doing some micro adjustments here as I go just to make 09:23.870 --> 09:31.550 sure that everything is aligned properly or it's got to duplicate it to GZ up to their GZ. 09:31.570 --> 09:33.550 I didn't need to do that twice. 09:33.740 --> 09:36.370 So I'm happy with that being four stories here. 09:36.380 --> 09:40.580 I can select this and move it down so it's covering up the right. 09:40.580 --> 09:42.590 There we go that's roughly in the right place. 09:42.780 --> 09:43.000 Okay. 09:43.020 --> 09:44.150 So now that's constructive. 09:44.150 --> 09:46.780 But that looks well silly. 09:46.820 --> 09:53.900 So now I've got all the basic pieces in place and you can do this not only with these are used blank 09:53.900 --> 09:59.300 walls and then put wind where I used blank walls I could put a door in here and windows down here. 09:59.360 --> 10:03.680 But now I have done that I'm going to select my blank wall piece which is over here and make sure it's 10:03.680 --> 10:11.120 the active object and of course go control L and make links to the object data and they go replace all 10:11.120 --> 10:12.860 of those parts very quickly. 10:12.860 --> 10:19.940 So you can build up a basic building block very quickly and then just substitute the parts in providing 10:19.940 --> 10:21.050 they all match. 10:21.050 --> 10:21.630 Brilliant. 10:23.410 --> 10:25.620 Now just got to make the rest of the church. 10:25.630 --> 10:26.550 So you guys in a bit. 10:28.870 --> 10:35.350 Okay so finally after moving lots and lots of bits about and making sure they're looking nice in this 10:35.350 --> 10:36.970 hierarchy over here. 10:37.000 --> 10:42.290 So then I can turn off individual parts of the church as I am when it's necessary. 10:42.370 --> 10:48.050 It's all come together rather well and much better than the first attempts at it. 10:48.180 --> 10:53.140 And it's taken a couple of hours to get to this point with all the tweaking and moving and the additional 10:53.140 --> 11:01.210 parts I've utilized a right angle triangle to make a roof section going along there and here and over 11:01.240 --> 11:02.560 on this side. 11:02.590 --> 11:08.740 I've got a right angle triangle just there so that when we're inside the church let's go to fly around 11:08.740 --> 11:09.720 mode. 11:09.850 --> 11:17.200 We can actually have a decent line coming in and not a square like it was just using a wall piece previously 11:17.200 --> 11:19.710 and it just looked absolutely horrible. 11:19.720 --> 11:21.730 Okay this is coming along really nicely. 11:21.730 --> 11:27.270 What problems did you come across when you start adding level of detail to your model. 11:27.280 --> 11:28.830 Did you have to remodel only think. 11:28.840 --> 11:31.120 Did you have to read skaer let me think. 11:31.120 --> 11:34.620 Did you accidentally destroy your model and have to start again. 11:34.780 --> 11:35.390 Don't worry. 11:35.410 --> 11:37.140 We all do it. 11:37.200 --> 11:43.700 It gave guys remember to show your work in the discussions and I will see you guys in the next lecture.
