WEBVTT 00:00.360 --> 00:04.580 Welcome to revisiting the mirror modifier in this video. 00:04.590 --> 00:09.660 You will learn how to use another object as the point of reflection. 00:09.660 --> 00:15.370 You going to understand that it is the origin itself that acts as the point of reflection. 00:15.480 --> 00:22.220 And finally see other objects rotational values change the axis of reflection. 00:22.530 --> 00:25.270 So let's hop straight on over into a blender. 00:26.070 --> 00:30.030 Okay so over in blender The first thing I'm just going to do. 00:30.090 --> 00:33.990 You don't have to follow me about as you're going to maximize the screen just to get a little bit more 00:33.990 --> 00:35.640 space on the screen for me. 00:35.990 --> 00:43.440 Okay so the first thing we need to do is show you this pax's of reflection. 00:43.440 --> 00:47.310 So we need an object to mirror and I'm going to use our scene here. 00:47.360 --> 00:52.120 I'm going to just hide a couple of things are going to hide the back drop and the camera. 00:52.170 --> 00:53.120 And the lamp. 00:53.190 --> 00:55.800 So it's just the basics that are in our scene. 00:55.870 --> 00:57.220 Okay now we've done that. 00:57.360 --> 01:01.190 If we go ahead and add a new object doesn't matter. 01:01.320 --> 01:04.050 Well I want to put it over here so I'm going to click over here. 01:04.050 --> 01:07.760 I'm going to just those three cursor values. 01:07.760 --> 01:14.160 So let's find the location of the three recurses scroll down a little location I want X and Y to be 01:14.160 --> 01:14.850 whatever they are. 01:14.850 --> 01:20.740 But on our y to be zero along here I want to sit on the x-axis itself. 01:22.900 --> 01:24.030 And Z. 01:24.120 --> 01:25.200 So also be 0. 01:25.200 --> 01:25.690 There we go. 01:25.700 --> 01:26.520 A balance much better. 01:26.520 --> 01:34.240 So we're going to create an object over here and let's actually add a mesh object and let's add all 01:34.290 --> 01:40.350 that's a monkey way that's very very pick and I'm going to scale the monkey right down. 01:41.600 --> 01:49.100 Okay so we're going to use Suzanne here the monkey as as basically our object that we're going to reflect 01:49.100 --> 01:49.900 in our mirror. 01:50.060 --> 01:55.510 So let's go straight and head in the mirror and modify us and then to get to the wrench at a modifier. 01:55.670 --> 01:59.820 And down here and generate we've got mirror. 02:00.410 --> 02:06.650 And so currently it's reflecting on the x y and z axis and it's reflecting about itself. 02:06.680 --> 02:09.490 Now it's actually reflecting about the origin. 02:09.710 --> 02:13.030 So if we were to sensor the cursor. 02:14.080 --> 02:18.960 So I'm just going to hide that red box that we place on the screen before we gets out the way. 02:18.960 --> 02:24.480 And I'm just going to click somewhere else just over here and in object mode. 02:24.510 --> 02:33.630 I'm going to go hit insets origin to 3D Curson the moment we do that you can see that all of the mirror 02:33.630 --> 02:36.360 modifiers axis down here. 02:36.600 --> 02:40.100 It's changed where they were before it was right on top. 02:40.320 --> 02:45.960 And afterwards it's here so we can use another object as a point of reflection. 02:45.960 --> 02:50.140 So the last option here on the mirror modifier is a mirror object. 02:50.170 --> 02:56.340 Now if we have a look at our lamp base its origin is smacked bang in the middle of it. 02:56.580 --> 02:57.780 And that's absolutely fine. 02:57.780 --> 02:59.070 That's what we want. 02:59.070 --> 03:05.080 So I'm going to grab Suzanne here with the mirror modifier and set the mirror objects. 03:05.100 --> 03:07.570 The lamp base there we go. 03:07.650 --> 03:08.570 Excellent. 03:08.580 --> 03:12.760 It's reflected on both sides and that's going to become very handy. 03:13.520 --> 03:20.580 The last thing to cover is how an object's reflection is also based upon the view. 03:20.600 --> 03:26.570 This object the mirror object down here based upon its rotation so sometimes you can end up with some 03:26.570 --> 03:28.260 funny stuff happening. 03:28.310 --> 03:33.590 So if I just I'm just going to uncouple the lamp base for the moment so we're reflecting around the 03:33.650 --> 03:36.900 monkey's own origins is there an origin. 03:37.190 --> 03:45.920 If I now go to the lamp base and just rotate It's 45 degrees on the y axis let's say it's tilted like 03:45.920 --> 03:46.970 that. 03:46.970 --> 03:48.860 Now if I go back to Suzanne. 03:48.950 --> 03:50.210 And. 03:50.850 --> 03:53.370 Mirror objects set it as the lamp base. 03:53.370 --> 03:58.510 We end up with a completely different reflection to what it was before. 03:58.590 --> 04:04.710 So you can see there how the mirror modifier can be very powerful but it can also be confusing at times 04:04.740 --> 04:11.410 because if you have rotated an object and then you decide to use it as a mirror object you may in fact. 04:11.410 --> 04:17.130 So if I go and take that all the way round you may find you need another access selected when it would 04:17.130 --> 04:18.780 have been a different one. 04:18.900 --> 04:20.890 If you just use the. 04:20.970 --> 04:23.370 In this case the objects own origin. 04:23.430 --> 04:30.000 Of course if you wanted a monkey on either side of here what you could always do is clear that I'm going 04:30.000 --> 04:37.770 to centre our scene with shift and see how the plane still in the scene and we use the number pad full 04:37.770 --> 04:39.940 stop to come back into our scene. 04:39.960 --> 04:48.020 Now the curse is in the centre of the set the origin of the monkey which is fine to the 3-d cursor. 04:48.190 --> 04:50.320 And now it's reflecting around there. 04:50.370 --> 04:55.660 So if we wanted it on the x-axis we've got that there. 04:55.680 --> 05:03.420 However with the end we could achieve a very similar thing with the lamp base if we set it to the lamp 05:03.420 --> 05:03.990 base here. 05:04.020 --> 05:10.280 Let's go to the lamp base etcetera and rotate it in the y axis by money minus 45. 05:10.290 --> 05:14.520 There you go your back to the same thing so one way of doing it is moving the origin. 05:14.520 --> 05:18.590 One is to use the another object's origin essentially. 05:18.780 --> 05:20.960 And of course they've both got their benefits. 05:21.120 --> 05:25.680 You don't want to start using a mirror modifier a move in an origin outside if you're also going to 05:25.680 --> 05:28.020 use that origin for something else. 05:28.170 --> 05:34.260 So there are a couple of things in blender that do use that origin one of which is pivot point scaling 05:34.260 --> 05:38.980 proportional editing physics etc. etc. The list goes on. 05:39.000 --> 05:44.460 So sometimes you will what if all you're doing is mirroring something and it has no other application. 05:44.460 --> 05:48.550 Fine move the origin quickly you can always move it back again later on. 05:48.780 --> 05:52.910 Alternatively I would use another object's origin. 05:53.010 --> 06:01.080 But again if you go and move that object later on say we're looking at this lamp base and it's not symmetrical 06:01.080 --> 06:04.110 and we go and rotate around the z axis. 06:04.110 --> 06:05.870 Well look what happens there. 06:06.150 --> 06:07.730 That could cause some problems. 06:07.740 --> 06:14.640 If you decide to rotate that round especially if you were moving it or animating other objects based 06:14.640 --> 06:15.030 upon. 06:15.030 --> 06:19.290 This may indeed start to go a bit funny. 06:19.420 --> 06:23.940 Now of course you can create a mirror empty or a plane and hide it. 06:23.940 --> 06:25.040 It's entirely up to you. 06:25.040 --> 06:29.560 There is always going to be more than one way of doing something like this. 06:29.910 --> 06:32.350 Okay guys it's Challenge time. 06:33.750 --> 06:38.040 I'd like you to build up the lamps them and the first arm. 06:38.310 --> 06:40.960 So make the joint at the top of the stem. 06:40.960 --> 06:46.280 I'll be using a boolean modifier and the union setting to make it one piece. 06:47.390 --> 06:52.540 Then finally use the mirror modifier for generating two arms coming out of our stem. 06:52.610 --> 06:59.210 These two arms will be a separate object and just to give you an idea of where I'm going of course your 06:59.210 --> 07:07.340 design might be slightly different so you may have to modify these instructions to your model but these 07:07.430 --> 07:10.660 are the front view and side view of the lamp for time. 07:10.670 --> 07:12.030 Going for. 07:12.140 --> 07:13.790 I'm going to try and go for. 07:13.790 --> 07:20.900 So you've got the stem on the screen coming up splitting into what you can only call a tuning fork type 07:20.960 --> 07:28.310 shape and then finally the two arms or actually there's only one object and we've used the mirin modifier 07:28.610 --> 07:34.640 and I've set the mirror modifier against the base there in order to generate the other arm. 07:34.730 --> 07:37.440 So pause a video now and give that a go. 07:39.790 --> 07:40.730 Welcome back. 07:40.870 --> 07:46.990 Let's hop straight on over in splendour right so I have opened up the file as it was when we started. 07:46.990 --> 07:51.710 So we just get rid of all the susanne's and any other changes that I've made to us scene. 07:52.090 --> 07:57.950 So the first thing I'm going to do is just hide a couple of bits and bobs that I don't want on anymore. 07:58.000 --> 07:59.400 The lamp can go. 07:59.450 --> 08:00.060 Yeah. 08:00.350 --> 08:07.690 The lamp base can stay the lamp reeg can go and the plane can go as well because that plane is a light. 08:07.690 --> 08:09.560 In fact I've still not move. 08:09.560 --> 08:14.080 I'm going to nest that under lamp so I know it's out of the way now. 08:14.080 --> 08:14.710 Right. 08:14.810 --> 08:19.160 And got remember of course to bring that back later anyway to the task at hand. 08:19.180 --> 08:27.880 First thing I'm going to do is place the 3-d cursor on top of us them and make sure that it's 0 0 on 08:28.000 --> 08:31.450 x and y coordinates. 08:31.450 --> 08:34.520 Next I'm going to add a cube to our scene. 08:35.770 --> 08:37.580 So it is in object mode. 08:37.590 --> 08:39.740 That's important at this point. 08:39.900 --> 08:43.890 Cube is far too big so we're going to scale it in. 08:43.920 --> 08:45.450 I'm just going to do this too. 08:45.480 --> 08:52.270 I for the moment or by I hand because I do want two bits either side of this. 08:52.350 --> 08:54.800 So I'm happy with that being the centre gap. 08:54.810 --> 08:58.230 By the looks of things of hopping to edit mode and just test. 08:58.410 --> 09:00.830 So I want it face select. 09:03.130 --> 09:04.260 I'm a bit too close. 09:04.260 --> 09:04.880 There we go. 09:05.010 --> 09:10.770 And I'm just going to extrude thinking that this way being forward some can extrude along the x axis 09:10.770 --> 09:14.580 here and extrude and just see how far that comes out. 09:14.590 --> 09:20.060 So looking at the lower lower corner they're about point three or so. 09:21.440 --> 09:31.120 KS So if I type but in point oh three there and here extrude by point not three. 09:31.870 --> 09:32.770 Excellent. 09:32.770 --> 09:36.170 Now I can scale the entire model not there. 09:36.190 --> 09:40.740 So everything on a scale it's on the y axis only. 09:43.370 --> 09:45.730 And we can see some artefacts happening here. 09:45.830 --> 09:50.710 And this is what can happen if you're working with a model to see if it was much smaller than this. 09:50.720 --> 09:52.700 It would be impossible to work with. 09:53.920 --> 09:54.520 So there we go. 09:54.520 --> 09:58.010 That's that's there some going to have to find the. 09:58.080 --> 09:59.540 But it's just going to select the stem match. 09:59.530 --> 10:04.910 We go to the modifiers air add a modifier a boolean modifier. 10:06.160 --> 10:14.140 Or when we want a union between that and the cube case something weird has gone on there let's just 10:14.230 --> 10:19.090 do that again and make sure everything's selective and once selected. 10:19.090 --> 10:25.030 So let's go in to the lamp reyk which is where that's hidden and the cube is on top. 10:25.030 --> 10:26.260 That's fine. 10:26.260 --> 10:29.600 Stem and modify a boolean. 10:29.890 --> 10:34.080 And we're going to go for a union with the cube. 10:34.630 --> 10:35.040 Okay. 10:35.050 --> 10:38.160 Now that's a bit weird something funny's going on here. 10:38.230 --> 10:41.370 I'm going to pause a video and just see what's going on. 10:42.990 --> 10:43.260 Okay. 10:43.260 --> 10:45.220 So something weird is going on here. 10:45.240 --> 10:49.600 I'm literally going to save my file just in case there's a bug going on. 10:49.900 --> 10:51.710 And I'm going to shut down blender. 10:52.840 --> 10:55.810 An hour ago when I re open. 10:56.700 --> 10:58.220 I animated lamp. 10:58.440 --> 10:59.500 Excellent. 10:59.560 --> 11:01.870 And I'm just going to try doing that again. 11:01.890 --> 11:04.060 So would the cube a union. 11:05.540 --> 11:11.420 Okay so I'm just going to remove the cube completely from our scene and I'm just going to whack another 11:11.420 --> 11:13.480 cube on read quickly. 11:14.590 --> 11:20.390 So in object mode mash cube cube cube scale it in. 11:22.820 --> 11:26.450 Kate I'm now going to select this one. 11:29.050 --> 11:32.190 A union with the cube again. 11:32.260 --> 11:33.430 Press apply. 11:33.990 --> 11:34.170 OK. 11:34.200 --> 11:42.240 Very interesting so it seems that something was causing some sort of a geometry screw up basically was 11:42.240 --> 11:46.170 causing the two things not to be unioned at all. 11:46.170 --> 11:48.740 Some is going to undo the operation. 11:48.810 --> 11:51.480 It could have been a bug in the program at some point. 11:51.510 --> 11:52.730 Crazy stuff going on. 11:52.770 --> 11:59.470 I'm going to edit this cube before and scale it in on the x axis. 12:00.390 --> 12:02.530 To about there I think. 12:03.530 --> 12:04.300 Excellent. 12:04.490 --> 12:08.790 And then I'm going to extrude out here by 0 point. 12:09.630 --> 12:11.140 Nought three. 12:11.250 --> 12:12.950 Your numbers may be different by the way. 12:13.040 --> 12:20.340 Don't have to copy exactly what I'm typing here some gimmick extrude here by point not three again because 12:20.340 --> 12:27.460 then these bits here I can extrude up in two hour two hour tuning fork. 12:27.540 --> 12:31.520 I'm not sure on the size or anything we can always go back and change that later. 12:31.530 --> 12:32.660 Can I have done that. 12:32.700 --> 12:40.630 Select the stem out select the stem give to union objects with our cube and click apply. 12:41.970 --> 12:44.840 So now when we hide our cube. 12:45.720 --> 12:46.390 Excellent. 12:46.410 --> 12:50.860 That's exactly what I wanted to do in the first place and it wasn't doing it. 12:51.030 --> 12:57.030 I honestly do not know why I think there was a complete bug out so I had to restart the whole bit again 12:57.270 --> 12:59.380 so don't panic if that happens to you. 12:59.730 --> 13:03.010 And I've finally just deleted that old q from the scene. 13:03.040 --> 13:07.230 So now we've cracked that we should have been a very straightforward part of the video. 13:07.500 --> 13:14.610 We're going to add in our arms so I'm going to click on this face here so first of all going to go into 13:14.640 --> 13:17.050 edit mode on the stem. 13:17.550 --> 13:19.400 I'm going to go in face select which I'm in. 13:19.430 --> 13:21.480 I'm going to select this face here. 13:21.540 --> 13:29.760 I'm going to use Shift an S to move our 3D cursor to the selected and it will automatically go to the 13:29.760 --> 13:30.490 centre. 13:30.690 --> 13:35.500 I'm now going to add or come out of edit mode and add. 13:36.860 --> 13:37.790 LANE. 13:38.060 --> 13:44.040 So we're going to build this arm from a plane and let's make it a little small Let's make the radius. 13:44.060 --> 13:49.250 Oh point snorts 3 seems what a lot of the others seem to be at the moment. 13:49.250 --> 13:49.810 Only a set. 13:49.810 --> 13:50.570 The. 13:50.900 --> 13:55.210 Let's just have a look at the axes here on the set the why rotation to 90 degrees. 13:57.860 --> 14:03.920 And that might have flipped it the wrong way for us and do minus 90. 14:04.340 --> 14:05.630 So the colour difference there was. 14:05.630 --> 14:09.820 Basically I'm going to end up having to flip Normal's if I hadn't done that. 14:10.040 --> 14:15.370 And let's see if I can get away with a 45 degree rotation on the x axis as well. 14:15.650 --> 14:19.470 No that's not going to do what I want it to so. 14:19.580 --> 14:21.100 At that plane again. 14:21.140 --> 14:28.570 I didn't mean to come away from it and it was just 90 degrees minus 90 on the y axis. 14:28.580 --> 14:30.110 I can get there minus 90. 14:30.110 --> 14:31.330 Brilliant. 14:31.550 --> 14:36.300 Then just rotate that around the x axis by 45. 14:36.350 --> 14:39.430 Perfect then extrude out. 14:40.530 --> 14:41.850 So let's go to edit mode. 14:41.850 --> 14:45.630 Strew down by point not three in a hour. 14:45.630 --> 14:49.580 Don't need extra geometry here so I'm not going to extrude from this point. 14:49.590 --> 14:51.660 I'm literally just going to move. 14:51.960 --> 14:57.520 And I think it's the x no it's going to be the y axis but not like that. 14:57.580 --> 14:59.210 No press on the y. 14:59.460 --> 15:01.490 Oh no is it Z then. 15:01.560 --> 15:02.940 No it must be x. 15:02.940 --> 15:03.410 Great. 15:03.530 --> 15:10.830 So on the x axis but pressing X Twice means the time going along the local axis. 15:10.870 --> 15:16.530 So finally I don't know how long maties So with the face still selected I'm going to hop into orthographic 15:16.530 --> 15:19.830 new mode and move around to the side. 15:19.890 --> 15:22.610 I figure there can be a little bigger so x x. 15:22.620 --> 15:23.880 There it go. 15:23.920 --> 15:26.240 Now of course you can edit this to your heart's content. 15:26.250 --> 15:28.360 Any point in the future as well. 15:28.650 --> 15:31.560 And there we go that's arm created. 15:31.620 --> 15:35.970 Now I know that later on in this scene I'm just going to clear that red border for the moment. 15:36.120 --> 15:42.300 I know later on in this scene I'm likely to be animating it and I'm going to be moving this base so 15:42.300 --> 15:45.240 setting the mirror points for the mirror modifier to this base. 15:45.240 --> 15:49.340 I don't think would be a good idea or any other moving parts. 15:49.350 --> 15:57.840 In fact in this case I'm going to create an empty and use that as a reference point song going to create 15:57.840 --> 16:00.060 an empty which I initially choose. 16:00.060 --> 16:04.720 I'm showing you a plain axis and I'm going to. 16:04.880 --> 16:09.120 I wanted that to be the 0 0 0 and I can do that here. 16:09.200 --> 16:11.330 0 0 0 in the. 16:11.330 --> 16:15.330 Operator panel perfect and ungathered ness. 16:15.340 --> 16:16.190 They're empty. 16:16.200 --> 16:25.080 I'm going to call it something first when I call it the mirror axis and I'm going to set that as a child 16:25.140 --> 16:26.880 of the sort not the stem. 16:26.880 --> 16:33.280 Sorry this plane's 0 0 1 because that needs to record lower. 16:36.790 --> 16:37.610 Air ago. 16:37.700 --> 16:38.010 Of. 16:38.080 --> 16:41.440 CAPS LOCK ON let me turn that off the lower arm. 16:42.350 --> 16:43.230 There we go. 16:43.670 --> 16:50.480 So finally we're going to add a modifier a mirror modifier to that arm being blind. 16:50.480 --> 16:50.990 There we go. 16:51.000 --> 16:54.790 Mirror modify and select the mirror objects as the mirror axis. 16:55.010 --> 16:58.130 Oh and I don't even have to select any other any other things. 16:58.130 --> 16:59.900 The x axis has already ticked. 16:59.960 --> 17:00.840 Perfect. 17:00.860 --> 17:02.570 How did you guys get on. 17:02.570 --> 17:07.000 Please share in discussions and I will see you in the next lecture.
