WEBVTT 00:00.450 --> 00:03.730 Welcome to the mirror modifier in this video. 00:03.730 --> 00:10.950 We're going to show you how to set up and use the mirror modifier and also start creating our nights. 00:11.010 --> 00:14.380 So let's go explore this mirror modifier over in blender. 00:14.520 --> 00:17.840 Okay so we've opened up a default blender file. 00:18.180 --> 00:24.270 I'm going to expand this area here so I can see our modifiers tab and just go straight away we can see 00:24.270 --> 00:30.210 the cube selected and add a mirror modifier nets under to generate options as all the ones before you 00:30.220 --> 00:33.310 so far and mirror is about halfway down. 00:33.330 --> 00:39.570 Once you've applied the modify it works in object mode and edit my notes not to reflect the object itself. 00:39.570 --> 00:45.470 If we move it to the side or over here as we apply to the mesh within the object itself. 00:45.480 --> 00:50.700 So let's just recenter it for ease if we hop on over into edit mode. 00:50.700 --> 00:54.260 We can start manipulating it and seeing what's going to happen. 00:54.330 --> 00:57.990 So I'm going to grab this virtex here and just pull it out slightly. 00:58.380 --> 00:58.890 Excellent. 00:58.890 --> 01:06.990 So what is happening here is it's within itself as you can see cause the whole cube itself is being 01:06.990 --> 01:12.550 modified at this point it's been reflected even though the x axis is ticked. 01:12.570 --> 01:18.540 It looks like it's being reflected down the y axis itself as if there was a mirror positioned along 01:18.540 --> 01:19.160 there. 01:19.500 --> 01:21.890 If we switch it to the just the y axis. 01:21.900 --> 01:26.510 Well it looks like you've placed a mirror arm on the x axis itself. 01:26.670 --> 01:33.420 And finally the z axis will as you've probably guessed that looks like it's sat here along this plane 01:33.600 --> 01:34.730 here itself. 01:34.890 --> 01:35.940 So that's how change. 01:35.950 --> 01:37.370 Which part is mirroring. 01:37.370 --> 01:40.640 And you can have them all turned on at once if you want. 01:40.640 --> 01:46.060 So now we've got a couple of options here now merge is quite important. 01:46.320 --> 01:53.430 When you're working on a model it pretty much just merges any vertices that happens to lie upon the 01:53.430 --> 01:54.760 plane of reflections. 01:54.760 --> 01:58.110 So down here for instance. 01:58.110 --> 02:04.110 So in this case if you were to modify this cube itself you'd start with half the cube. 02:04.110 --> 02:06.770 So let's go back now and just do that. 02:07.050 --> 02:11.540 Let's just click the little icon so we can't see the modifier being applied. 02:12.420 --> 02:15.290 We'll grab this face over here. 02:16.170 --> 02:23.290 And we're going to move it in the X axis will move it in the x axis. 02:23.310 --> 02:24.480 This isn't working. 02:24.480 --> 02:24.920 Why not. 02:24.930 --> 02:26.610 Oh I've accidentally deleted it. 02:26.610 --> 02:27.540 Well done. 02:27.540 --> 02:34.350 I'm going to move it in the x axis by one and that will push it up against this X equals zero threshold 02:34.380 --> 02:34.870 here. 02:35.130 --> 02:40.980 So now when we turn it back on again we don't get the weird stuff happening and the modifier itself 02:41.010 --> 02:46.280 means that where these vertices join in the middle it will only have one set it won't duplicate them 02:46.290 --> 02:48.890 on top of one another clipping. 02:49.020 --> 02:56.220 Well it prevents vertu's going through the mirror Turing transform and the vertex grouping mirrors vertex 02:56.340 --> 02:57.450 groups. 02:57.630 --> 03:05.320 So now that we know how the mirror modify works let's go hop over and start creating our nights. 03:05.430 --> 03:12.270 So I'm going to open up the air warith Sit here we've got the bass and I stopped for in the archive. 03:12.420 --> 03:14.580 The low the chest piece. 03:14.580 --> 03:15.010 Here we go. 03:15.020 --> 03:17.240 Chest piece base we can start with that one. 03:19.090 --> 03:21.960 So now that we've opened up are low poly chest B space. 03:21.970 --> 03:25.640 First of all I'm just going to add the necessary. 03:25.660 --> 03:28.430 I'm going to call it night for a start. 03:28.900 --> 03:32.070 And up here I'm just going oh sorry. 03:32.070 --> 03:35.140 Down not up but down there again. 03:35.140 --> 03:39.070 I'm just going to change the image that we're working from to the night itself. 03:39.070 --> 03:40.160 So I've got something now. 03:40.160 --> 03:42.520 Well turn the pasta up so I can see it. 03:42.520 --> 03:43.420 And just check. 03:43.420 --> 03:46.580 That's all working as it should do. 03:46.630 --> 03:47.230 Perfect. 03:47.250 --> 03:50.440 Ah night is ready to start tracing out. 03:50.440 --> 03:56.340 So final thing here is to just save it as and called it low poly night. 03:58.830 --> 03:59.660 Perfect. 03:59.670 --> 04:04.430 Now that's called night we just need to apply the mirror modifier itself. 04:04.470 --> 04:09.360 So you're going to have to cut this in half and then apply a modifier to it. 04:09.450 --> 04:16.370 Now there's one final thing that we need to discuss before you go ahead and use the mirin modifier. 04:16.530 --> 04:23.310 And that's if your origin isn't in the right place or you start moving or rotating stuff around you 04:23.310 --> 04:25.750 can cause a bit of disruption to the mirin modifier. 04:25.920 --> 04:34.320 So just as a quick example I'm going to toggle limit selection to visible off and just using a border 04:34.320 --> 04:34.970 select. 04:34.980 --> 04:42.580 I'm going to select some of my mesh and delete it to just show you what can happen. 04:42.630 --> 04:44.210 I just want to delete vertices. 04:44.220 --> 04:46.560 In this case and we've got half a model left. 04:46.620 --> 04:53.010 Now ordinarily if you hop into object mode and go to the mirror modifier and apply. 04:53.930 --> 04:58.470 That's we would get a reflection going on. 04:59.180 --> 05:01.540 I seem to be blind or it's not appearing. 05:03.090 --> 05:06.860 Let's just make sure I'm applying it the right thing it's called night that's fine. 05:06.870 --> 05:08.390 So try that again. 05:08.530 --> 05:09.990 Mira modifier. 05:11.180 --> 05:11.830 There we go. 05:11.830 --> 05:13.750 And he did it on the y plane. 05:13.870 --> 05:14.260 Right. 05:14.300 --> 05:17.560 So now I'm reflecting around there it looks absolutely fine. 05:17.660 --> 05:25.400 However if for some reason this one was rotated around slightly and not aligned it will cause some things 05:25.400 --> 05:26.720 to go wrong. 05:26.720 --> 05:33.500 The other thing that can happen is you've created your geometry or moved your origin at some point. 05:33.500 --> 05:36.580 Let's pop the origin over here. 05:36.680 --> 05:39.860 You'll see that it also changes the model quite drastically. 05:39.860 --> 05:45.670 And what she thought the mirror modifier would have done changes it a little. 05:45.830 --> 05:47.380 Not in a good way. 05:47.390 --> 05:54.850 So in that case make sure that you're aligned properly and B you haven't rotated. 05:54.890 --> 05:56.030 This is the common one. 05:56.030 --> 06:01.070 You've rotated half your object ever so slightly and that causes things to break apart from skin to 06:01.070 --> 06:02.060 undo quickly. 06:02.060 --> 06:08.750 So we've got this area here and in edit mode if you've ended up with something that's looking like VAT's 06:08.750 --> 06:09.730 or like fat. 06:09.740 --> 06:13.620 In fact if I wrote it it ran the z axis That's more than likely what would happen. 06:13.640 --> 06:16.450 You'd have the sheer line them back. 06:17.350 --> 06:23.030 So they were straight along the access you're reflecting along in order for it to work. 06:23.050 --> 06:27.820 So with that little little thing that I know is going to trip up some of you if you haven't made this 06:27.820 --> 06:31.310 space exactly square it's time for a challenge. 06:32.170 --> 06:35.180 I would like you to set up a mirror modifier. 06:35.500 --> 06:40.540 So we're going to set up a mirror modifier on our night ready to construct the head of the night so 06:40.540 --> 06:43.270 it's even reflected on both sides. 06:43.330 --> 06:48.910 And I'd like you to make sure you cut the base into along the mirror plane itself so you'll end up with 06:48.910 --> 06:53.100 the mirror modifier reflecting the other half of the base you've just deleted. 06:53.330 --> 06:55.740 The video now and give that a go. 06:57.720 --> 06:58.670 Okay guys. 06:58.860 --> 06:59.870 Welcome back. 06:59.910 --> 07:01.780 Let's go apply that mirror modifier. 07:03.240 --> 07:10.230 So back over in that blender let's start applying this mirin modifier so you'll want to I'm looking 07:10.230 --> 07:11.580 at it I believe from the front. 07:11.580 --> 07:12.160 I'll just check. 07:12.180 --> 07:12.890 Yes I am. 07:13.080 --> 07:16.860 So I'm either going to pick the left or the right side to do it doesn't really matter. 07:17.160 --> 07:24.020 And I'm going to select everything on this right hand side so let's just highlight it with the bot board 07:24.020 --> 07:24.660 a select. 07:24.660 --> 07:25.050 I will say. 07:25.050 --> 07:26.570 Box select. 07:26.680 --> 07:33.360 Missed it there but I think only to select all the way through our model is well yes we so just do that 07:33.460 --> 07:33.970 again. 07:33.990 --> 07:40.770 Let's go back round to the front turn on this option here which is to limit selection or rather turn 07:40.830 --> 07:42.370 limit selection off. 07:43.240 --> 07:46.210 Press B for border highlight through. 07:46.210 --> 07:46.790 Brilliant. 07:47.080 --> 07:52.750 And this way we can actually just delete the vertices and then delete the faces and edges that also 07:52.750 --> 07:54.040 these vertices touch. 07:54.220 --> 07:57.090 Let's try that now x and delete the vertices. 07:57.130 --> 07:59.010 I dealt with half a model. 07:59.020 --> 08:04.810 Now we also end up with no base on our model and nothing at the top hit nothing around the top here 08:04.840 --> 08:07.040 isn't going to be an issue for us. 08:07.390 --> 08:09.440 But this bottom bit may be. 08:09.490 --> 08:14.440 We might forget the top bit we're going to build upon but the bomblet we're likely to forget. 08:14.440 --> 08:16.670 I certainly am likely to forget. 08:16.770 --> 08:22.000 On going to do there is whilst I remembered I'm going to select the edge going round and just put a 08:22.000 --> 08:24.090 face across there with the fill. 08:24.130 --> 08:28.210 There will be an end gone but since I'm not going to see it since it's hidden away. 08:28.240 --> 08:30.870 I'm fine with it being on the bottom there. 08:31.300 --> 08:38.290 Okay so now batstone we just need to apply the mirror modifier So I'm going to hide these bits and bobs 08:38.290 --> 08:41.210 here so I can see more of the work I'm working on. 08:41.220 --> 08:47.170 I'm just going to pull this out the mirror modifier going to that straight away. 08:47.470 --> 08:50.490 Oh and I've got the right axis straight away as well so that's bringing. 08:50.490 --> 08:54.910 I don't need to do anything else now I'm not going to apply the modifier just cannot keep it because 08:54.910 --> 09:01.030 they want to start modifying this side of the horse later on it will automatically apply to this side 09:01.090 --> 09:02.260 as well. 09:02.260 --> 09:02.980 Brilliant. 09:02.980 --> 09:04.440 How did you guys get on. 09:04.450 --> 09:06.590 I will see you in the next lecture.
