WEBVTT 00:00.090 --> 00:03.780 Welcome to a better camera control in this video. 00:03.780 --> 00:07.140 You use a different way of moving the camera. 00:07.140 --> 00:13.800 See this gives you better control over what the camera is pointing at combined with fly mode for good 00:13.800 --> 00:17.770 control and learn how to track a target. 00:17.790 --> 00:21.460 So let's go play with the camera and hop on over into a blender. 00:22.220 --> 00:29.060 So back over in blender here just a quick fly around my model real really quick just to let you know 00:29.060 --> 00:32.720 I've sorted out these ceiling pieces or at least solidify them for the moment. 00:32.720 --> 00:34.050 I work on them more later. 00:34.220 --> 00:37.660 I sorted out a whopping great big hole that was in this tower. 00:38.120 --> 00:44.060 And I did I don't think I actually move this place down here because it doesn't look like it's actually 00:44.060 --> 00:45.270 out of alignment. 00:45.470 --> 00:48.770 So I think that I've already moved and corrected that. 00:48.770 --> 00:54.350 The only place that I haven't sorted out yet is this hole over here because I'm going to make a specific 00:54.440 --> 00:57.360 roof to cover this area. 00:57.380 --> 01:02.780 I might try and make it out of those primitives that we've already made up and see how that works. 01:02.810 --> 01:08.600 But now more on about Cameron draw in fact what we're about to do not only applies to cameras but you 01:08.600 --> 01:14.770 can also use it to move other objects with other objects so it's universal in many ways. 01:14.960 --> 01:19.370 So first of all let's have a look at combining it with fly mode. 01:19.370 --> 01:21.300 So this is very straightforward. 01:21.320 --> 01:23.850 And of course very powerful. 01:23.910 --> 01:28.520 So we've already seen that we can get a particular view very quickly if this is the view that we have 01:28.640 --> 01:30.410 what we actually want. 01:30.440 --> 01:35.720 We can actually move the camera to that view points straight away without having to that going go and 01:35.720 --> 01:38.120 grab the camera and move it to the appropriate location. 01:38.120 --> 01:44.180 So we're all aware of going to the camera itself go into the properties and locking the camera to the 01:44.180 --> 01:49.590 view and then being able to move it around but we do have to be looking through the camera to do that. 01:49.760 --> 01:54.390 So we press 0 now we're now looking through it and we can reposition the camera like that. 01:54.530 --> 01:55.670 That's absolutely fine. 01:55.670 --> 01:57.030 We can move it in and out. 01:57.050 --> 02:00.620 But as you can see it's quite granular it skips quickly. 02:00.620 --> 02:06.950 So yes you can fiddle about with that for a while moving it here rotating it coming in etc. But eventually 02:06.950 --> 02:09.140 that's going to become quite tiresome. 02:09.140 --> 02:15.920 However if we combine this with the Flymo route we can move to a position that we want just simply by 02:16.250 --> 02:17.650 hitting shift and f. 02:17.660 --> 02:21.140 Now we can fly around and go to the new viewpoint that we want. 02:21.150 --> 02:22.600 We can look in through this window. 02:22.610 --> 02:23.780 Hello everybody. 02:23.780 --> 02:25.400 Where is the manequin areas. 02:25.730 --> 02:31.790 Okay so that's one way we can do it but we've already got a view set up over here so let's just hop 02:31.850 --> 02:33.200 out of there. 02:33.230 --> 02:36.460 Looks like I have moved my view unfortunately. 02:36.500 --> 02:43.150 So let's just sort this out hop back into flying mode real quick zoom back to where we were before to 02:43.160 --> 02:49.370 say we wanted this particular view and we didn't want to faff about with trying to get the camera into 02:49.370 --> 02:50.320 the right position. 02:50.360 --> 02:58.190 We can actually go to the View menu and go to a line view and there's got a series of options here so 02:58.190 --> 03:03.680 we can align view to active so we can look down up left right et cetera. 03:03.980 --> 03:09.980 But one of the very powerful ones in this are let go of control there a line active camera to the view. 03:09.980 --> 03:15.800 So we've got an active camera which is the main one and the one whose viewpoint we will see if we hit 03:15.800 --> 03:20.930 render But we can assign that or line the active camera to the view and we see let's control Oulton 03:20.960 --> 03:25.910 no pants zero if we want to do that and when we click that there we go. 03:25.910 --> 03:28.870 The camera automatically moves to this position. 03:29.120 --> 03:32.200 Now is a course useful to have multiple cameras in the scene. 03:32.330 --> 03:36.350 So you don't have to keep moving one but we'll leave that for a bit. 03:36.470 --> 03:44.750 Now another way that we can actually track something in the scene is either placing an empty or in this 03:44.750 --> 03:47.210 case I'm going to use my mannequin as an example. 03:47.210 --> 03:54.200 I can track that object through the scene and this is very very powerful and very useful. 03:54.200 --> 04:00.620 Now what we going to be doing is constraining the Cambers movement based upon certain parameters. 04:00.620 --> 04:07.310 So in this case we go to the constrained tab on the properties window and we're going to add an object 04:07.310 --> 04:07.750 constraint. 04:07.760 --> 04:13.130 And there are lots of constraints that we can do and we want under tracking. 04:13.130 --> 04:16.880 We want it to track to a particular object. 04:17.060 --> 04:19.360 And I'm going to select my mannequin here. 04:21.210 --> 04:23.420 0 0 I WANT THAT one. 04:23.430 --> 04:24.720 That's the one that's in the scene. 04:24.810 --> 04:27.540 Now this may look a bit odd at the moment and it. 04:27.550 --> 04:32.380 Well it will look a bit odd because we've not set up the tracking constraints properly. 04:32.380 --> 04:37.530 But typically if you want it to rotate around you're going to want these particular settings you're 04:37.530 --> 04:44.790 going to want it the miner said and why and then where ever we move. 04:44.790 --> 04:50.790 So that's two minors said and the UP IS WHY can be a bit confusing and we'll go through that in more 04:50.790 --> 04:52.050 detail in a moment. 04:52.140 --> 04:59.000 But basically now when we move our mannequin about the camera or automatically tracks. 04:59.040 --> 05:05.430 So if I lock him to the y axis the cameras stay still and tracks in moving down the church. 05:05.430 --> 05:08.550 In fact if I turn off snapping it would be a lot smoother. 05:08.560 --> 05:09.420 There we go. 05:09.690 --> 05:12.390 So there he goes down there and the camera is tracking him. 05:12.600 --> 05:13.770 That's very powerful. 05:13.770 --> 05:18.090 The other thing we can do here is move the camera itself. 05:18.090 --> 05:22.280 So if I go and pick up the camera and move the camera. 05:22.320 --> 05:23.640 So let's go to the camera. 05:23.640 --> 05:24.430 Here it is. 05:24.540 --> 05:26.120 And go ahead and move that. 05:26.250 --> 05:32.460 It's also constrained and looking at the object again whether that's the focal point that you want to 05:32.460 --> 05:35.640 use or anything else so I can pop the camera over here. 05:35.640 --> 05:40.700 And then if I go and grab this mannequin and move it outside there we go. 05:40.740 --> 05:41.700 Still following. 05:41.740 --> 05:45.480 No matter where we decide to put a mannequin. 05:45.480 --> 05:47.100 Very very powerful. 05:47.100 --> 05:53.520 Now let's have a look at the constraints themselves because we can get the viewpoint to follow in many 05:53.520 --> 05:54.080 different ways. 05:54.090 --> 06:00.540 And the easiest way of visualizing this is to actually track the object when it's in line with it. 06:00.540 --> 06:02.890 And then we can see what's going on. 06:02.890 --> 06:07.350 So I'm going to move the camera itself to my now are not on there. 06:07.390 --> 06:11.640 I'm going to move the camera to zero and zero which is by the entrance way for church. 06:11.640 --> 06:16.500 There we go we're looking at that and I'm just going to move the camera forward a little so it's a little 06:16.500 --> 06:17.460 bit closer. 06:17.550 --> 06:22.860 And then finally I'm also going to move the mannequin So the mannequin airs at X equals zero as well. 06:22.860 --> 06:24.390 So they're in line. 06:24.390 --> 06:28.330 Now let's move out of this view point itself. 06:28.980 --> 06:33.960 Lock camera two of you turn it off so we can ways around and see what's happening from above. 06:34.890 --> 06:35.700 There we go. 06:35.700 --> 06:41.040 So at the moment if we go to the camera itself and look at the constraints if we look into the X axis 06:41.040 --> 06:47.750 we see that it's now looking along the x axis and of course minus X axis looks the other way. 06:47.790 --> 06:54.120 So if we go and z looks backwards so that's good if you've got a an object moving forward and you want 06:54.120 --> 07:01.080 to track it from the other side rather So looking sort of a selfie if you will rather than a tracking 07:01.080 --> 07:02.570 camera following behind. 07:02.730 --> 07:10.680 So X looks along the x axis and that's very powerful if you imagine too if one viewpoint was being followed 07:10.680 --> 07:15.900 and perhaps tracking and trying to search for something here in my head an aircraft in flight if you 07:15.900 --> 07:21.990 were flying in formation and you wanted the other plane to control where the camera was going but keep 07:21.990 --> 07:27.150 them relatively close to one another you can do that and of course you can turn down the influence a 07:27.150 --> 07:35.020 little here to actually control that with a little more finesse So it's not so spot on. 07:35.040 --> 07:41.700 Now obviously when you move an object too far if the influence isn't one eventually it all disappear 07:41.700 --> 07:42.870 out of frame. 07:43.050 --> 07:50.910 So we can set here the up direction of the camera now it's quite confusing that up is why if we pick 07:50.910 --> 07:56.520 said we see it looks down which is the default position a camera would be if you imported it in to the 07:56.520 --> 07:57.420 scene. 07:57.420 --> 08:05.550 So because it's been rotated 90 degrees to look forward in this case we see. 08:05.670 --> 08:11.130 Whereas Z used to be up and down it's now in a completely different orientation in fact. 08:11.130 --> 08:13.720 Now why is up and down. 08:14.100 --> 08:18.250 Now we can experience with it locked to the two on x. 08:18.270 --> 08:21.230 If I go ahead and move this mannequin now. 08:21.450 --> 08:28.220 It will track it is if it was very much next to it so very useful in certain circumstances. 08:28.290 --> 08:33.180 Perhaps if you were controlling a different object rather than a camera it's quite important that the 08:33.180 --> 08:36.780 camera is actually focussed at the object we want. 08:36.780 --> 08:43.590 So in that case let's go to the camera again minor said and then no matter where these two are positioned 08:43.640 --> 08:50.280 whether the mannequins over here in the sky and the camera's over here it automatically tracks object 08:50.310 --> 08:52.540 which is incredibly powerful. 08:52.950 --> 08:55.610 And of course I've got a challenge for you guys. 08:55.620 --> 09:02.550 Now I would like you to set up some cameras set up multiple cameras so we don't have to keep moving 09:02.550 --> 09:09.330 just one introduce a place holder or an empty for a tracking camera much like I have got my mannequin 09:10.470 --> 09:14.870 and then render your building from a couple of different camera views and share. 09:14.880 --> 09:17.440 Remember we're mainly focussing on the interior. 09:17.440 --> 09:20.640 But if you've got a call exterior please share that as well. 09:20.640 --> 09:26.830 Now do remember that you need to set a particular camera as active in order to render from it. 09:26.940 --> 09:29.690 Suppose a video now and give that a go. 09:31.990 --> 09:32.530 Okay guys. 09:32.560 --> 09:33.190 Welcome back. 09:33.190 --> 09:37.670 I'm going to go and set up my cameras now so we don't have to keep moving them about all the time. 09:39.150 --> 09:40.580 Right some back over in blender. 09:40.590 --> 09:42.550 And the first thing I'm going to do. 09:42.570 --> 09:47.220 Well I don't need to do the tracking camera already set that one up and he's tracking the mannequin. 09:47.220 --> 09:50.470 I don't mind where that's positioned for the moment. 09:50.600 --> 09:56.210 Well I might actually move them into a bit more of an interesting position so let's look from the viewpoint. 09:56.370 --> 09:57.430 That's no good. 09:57.510 --> 10:00.990 This is perhaps it's an angel floating through the church. 10:00.990 --> 10:02.700 Who knows. 10:02.710 --> 10:04.580 Well let's try one. 10:04.740 --> 10:05.640 Looks a bit better. 10:05.640 --> 10:11.960 Looks like we're not set here his origin at his feet which is caused me a few problems. 10:11.970 --> 10:17.670 This is one of the reasons why you want to make sure that you have the origin in a logical place for 10:17.670 --> 10:19.620 using your model. 10:19.650 --> 10:23.120 So there's my mannequin Let's see what the view looks like at the moment. 10:23.130 --> 10:25.350 That isn't very interesting. 10:25.350 --> 10:29.730 So what I'm going to do is I'm going to move him around but lock him so down and go off the floor. 10:29.820 --> 10:32.870 And where shall I pop him. 10:34.850 --> 10:36.480 That might be an interesting render. 10:36.500 --> 10:43.940 I will set that I'll just get my camera and move it around just a little so I can see more of those 10:43.940 --> 10:44.450 rooms. 10:44.450 --> 10:46.300 I'd love to see how they're rendering out. 10:46.530 --> 10:48.710 Okay so that's one camera all sorted. 10:48.710 --> 10:54.310 I'm going to go ahead and just duplicate this particular camera and hop out of its view. 10:55.570 --> 10:59.950 And duplicate it of course it's already going to have some constraints on it. 11:00.040 --> 11:02.740 So I'm going to call this exterior. 11:03.180 --> 11:07.920 So I do want to just have a quick peek at my exterior as I'm working. 11:07.920 --> 11:10.750 I don't want it tracking to anything so I can remove that. 11:10.900 --> 11:15.790 I'm also going to create an empty at this point that's going to control all of four cameras or just 11:15.790 --> 11:20.100 store them in the hierarchy so plain axis. 11:20.410 --> 11:21.850 Do I care where it's placed. 11:21.850 --> 11:24.500 Not particularly at this point. 11:24.670 --> 11:28.720 I've opened up that's the empty here and of the call that cameras. 11:28.900 --> 11:34.210 It looks like I've managed to open up my entire hierarchy which may be a bit problematic but I'll just 11:34.360 --> 11:36.050 shut it back down. 11:36.400 --> 11:41.500 So I've got a camera here and let's call this one tracking camera. 11:41.590 --> 11:47.400 It's important I know what they are so that's lift that up and put that on the camera exterior. 11:47.450 --> 11:54.290 Let's put that on the camera and I want a another one and I'm going to just duplicate the exterior. 11:56.720 --> 11:59.970 Then where it is at the moment ungathered called it interior. 12:01.250 --> 12:06.120 And I'm going to leave it there with three separate cameras so let's make this the active camera. 12:06.140 --> 12:10.500 And of course what we can do here is go to the camera propertys. 12:11.900 --> 12:19.040 Here cameras active camera is numbered zero and then set the objects as the camera is control number 12:19.040 --> 12:19.780 had zero. 12:19.970 --> 12:20.540 So there we go. 12:20.540 --> 12:22.270 This is now v active camera. 12:22.400 --> 12:28.550 I'm going to set the interior one right back towards the entrance way and let's look at the view. 12:28.550 --> 12:31.120 I'm going to switch on what camera to view. 12:31.550 --> 12:35.630 That's looking pretty good in fact before I do that I'm just going to zoom in a little so I'm seeing 12:35.630 --> 12:40.780 what the cameras are seeing rather than a slightly zoomed out version. 12:40.850 --> 12:43.780 Let's lift the camera up ever so slightly. 12:45.130 --> 12:46.200 Let's make it look epic. 12:46.210 --> 12:52.510 By placing the camera a little bit lower and it's being framed by the door or the walls there so that's 12:52.540 --> 12:53.760 absolutely fine. 12:53.770 --> 12:58.050 So that's that camera set up the exterior one well it's not exterior at the moment. 12:58.210 --> 13:04.300 So again I'm going to use short Cahir controller nump had zero to switch around to it and I'm going 13:04.300 --> 13:06.100 to fly that one out. 13:06.100 --> 13:11.700 Now what I could do here for the exterior is certainly have a ground plane as well. 13:11.770 --> 13:16.390 So I'm going to add that in a few moments in fact I'm going to add it in now before I do anything else 13:16.390 --> 13:23.290 with this camera because if I start doing other things with the camera I might actually push it below 13:23.290 --> 13:26.140 this plane and that wouldn't be very good. 13:26.140 --> 13:30.670 So I'm just going to scale that up massively and then move it's like the in the wide net. 13:30.830 --> 13:35.280 That just gives me a bit of a ground play and I'm going to set it slightly below the surface as well. 13:35.290 --> 13:40.750 It turns out that that is roughly 100 by 100 something the type that in and it looks like I'm going 13:40.750 --> 13:44.510 to have to look down a little. 13:44.530 --> 13:48.080 Yes I'm going to have to move it slightly below the surface. 13:49.420 --> 13:53.510 Let's go up to the actual position that always helps of minus point one. 13:53.800 --> 13:57.910 Okay so that's in the right place there so let's go back to this exterior camera. 13:57.910 --> 14:05.730 In fact we can just look from its viewpoint and lock the camera at a view of as she fills up the. 14:06.620 --> 14:08.060 The lens quite nicely. 14:08.060 --> 14:14.090 But I want to look down on ever so slightly don't need to be back here a little wider angle. 14:14.090 --> 14:19.610 I want to have a slightly wider angle someone to go to the camera properties and change the focal length 14:19.610 --> 14:25.720 here down to let's say 24 then I should be able to fit more of the ground and more of the church. 14:25.730 --> 14:27.130 I'm going to go slightly wider again. 14:27.130 --> 14:28.330 Going to go for 18. 14:28.490 --> 14:31.840 Of course you do risk stretching and distorting the image. 14:31.850 --> 14:35.550 But if you want to fit the whole thing in that might be what we need to do. 14:35.780 --> 14:40.130 Of course now I'm going to render these out and see what they're looking like. 14:41.380 --> 14:43.360 Hope yours are looking pretty good. 14:43.360 --> 14:47.010 Here are mine on the screen right now. 14:47.040 --> 14:49.440 I hope you've shared your work in the discussions. 14:49.600 --> 14:52.830 And of course I will see you guys in the next lecture.
