WEBVTT 00:00.270 --> 00:02.020 Welcome to Lakers. 00:02.220 --> 00:06.750 In this video you will know how to turn layers on and off. 00:06.750 --> 00:09.300 Turn on the lay a management tool. 00:09.300 --> 00:14.830 Understand layers are useful for working on separate parts of a scene or even model. 00:15.150 --> 00:23.070 Realize if a layer is off the final render will not contain anything that was on that layer. 00:23.610 --> 00:26.990 So let's go have some fun with layers over in blender. 00:27.880 --> 00:31.150 Okay so now we're over in blender. 00:31.150 --> 00:38.710 Take a look at the 3D Ed had a tall bar so down here we have 20 squares. 00:38.710 --> 00:39.520 How cool is that. 00:39.520 --> 00:42.780 That will actually turn on and off certain layers. 00:42.940 --> 00:49.720 And if he use the number keys across the top of the keyboard providing you don't have no pad emulation 00:49.720 --> 00:50.540 turned on. 00:50.650 --> 00:55.260 You'll also notice if we if He glanced down at the bottom of the screen here when you press one that 00:55.260 --> 01:01.470 is on there one two three four five etc. etc. and it goes all the way to zero. 01:01.480 --> 01:08.860 Now if we want to play something on a particular player we simply select that layer and let's just add. 01:08.860 --> 01:13.480 I don't know a Taurus so that we've got a doughnut floating in the sky on Layer 3. 01:13.480 --> 01:19.120 You can also see it has a little orange blob on it when it's got a mesh object on it. 01:19.120 --> 01:24.540 So if I add I don't know a plane here and just scale that up. 01:25.150 --> 01:27.740 And we've got two separate layers now. 01:27.760 --> 01:29.510 Layer 1 and 3. 01:29.530 --> 01:37.990 Now that one makes sense so if we so went over to lay a three and selected object we can move it to 01:38.020 --> 01:43.500 another layer so you can move any object to another layer simply by going to object. 01:43.700 --> 01:49.000 And at the top of this drop down or drop up in this case we have moved the layer and we can see the 01:49.000 --> 01:50.110 short cut keys. 01:50.740 --> 01:53.280 And that is it when you're an object mode. 01:53.410 --> 01:58.150 So when we click on that we get the same thing that we can see down the bottom here so when we press 01:58.240 --> 02:02.030 em moved to layer and I'm going to move that to Layer 2. 02:02.140 --> 02:02.700 There we go. 02:02.800 --> 02:05.870 If we click on there too we shall see our doughnuts again. 02:06.100 --> 02:07.000 Brilliant. 02:07.000 --> 02:13.660 Now if you want more than one player turned on at once you simply hold down Shift as you click on those 02:13.660 --> 02:14.570 layers. 02:14.590 --> 02:22.530 You can also just drag across the layers and it will also enable all disable those particular layers. 02:23.910 --> 02:25.620 Now just to demonstrate. 02:25.620 --> 02:33.900 If I select Layer 3 and go and render the image it renders absolutely nothing. 02:33.900 --> 02:41.550 If I hop back to the 3D view and turn on our Taurus and render that we end up with the Taurus in the 02:41.550 --> 02:41.930 scene. 02:41.940 --> 02:44.070 But no ground plane. 02:44.070 --> 02:46.520 But if I have both turned on. 02:47.600 --> 02:49.460 And go to render render image. 02:49.550 --> 02:55.820 It will render both of them so is very important that what you want to appear in your final render or 02:55.850 --> 02:59.340 animation the layers are actually turned on. 02:59.360 --> 03:05.420 Now that has a great benefit of course that things that were working on or other other bits and bobs 03:05.420 --> 03:10.600 that are used to create our scene can be shelved to a different layer. 03:10.590 --> 03:14.530 That's not going to be visible all of the time with the main scene. 03:14.720 --> 03:21.590 So one final thing I would be really nice to name these layers and we can do that with the layer management 03:21.590 --> 03:26.330 tool which is not on by default so apology's we're going to go back. 03:26.330 --> 03:27.800 I forgot about this add on. 03:27.980 --> 03:34.400 We need to go back to file and go to the user preferences and turn on one called Layer management is 03:34.400 --> 03:37.740 actually quite high up the list class under the 3D view. 03:37.760 --> 03:39.120 Layer management. 03:39.320 --> 03:43.660 If I put a tick in that box it's an I'm going to save my user settings. 03:43.670 --> 03:46.210 It's gonna be in the tool shelf. 03:46.220 --> 03:51.970 It used to exist over in the properties panel but it doesn't any more it lives in the talk shop. 03:51.980 --> 03:58.130 I'm going to bring this tool shelf out so it takes up a third of my screen and further down. 03:58.130 --> 04:02.350 We've got the layers tab and we have to drop down layer management. 04:03.070 --> 04:08.250 And labour groups and obviously labour groups is how you group players together. 04:08.500 --> 04:15.070 Okay so on here we've got layer's 0 0 1 out we can call that one the for the moment I'm going to call 04:15.070 --> 04:18.310 it plain and I'm going to call this one. 04:18.580 --> 04:19.300 Doughnuts. 04:19.300 --> 04:20.310 Why not. 04:20.590 --> 04:22.360 So we've got plain and doughnuts. 04:22.480 --> 04:26.800 Now we can lock the layers over on the left here we've got a couple of options. 04:26.810 --> 04:29.760 This padlock you'd think would lock the. 04:29.950 --> 04:36.040 But it doesn't what it does is it prevents you selecting the objects on that layer so it locks the objects 04:36.040 --> 04:37.080 on that layer. 04:37.180 --> 04:41.190 And we can see that the symbol the little arrow symbol here has gone greyed out. 04:41.230 --> 04:48.760 And if you cast your eyes over to the outliner it's also made them unselect Tibble over here to every 04:48.790 --> 04:51.380 click vose off we see they all come back again. 04:51.460 --> 04:55.810 You can also do a bit of moving if you want to move things between layers in here. 04:55.810 --> 05:03.030 So with the Taurus selected we can click on this little dots here on the plane one. 05:03.220 --> 05:06.180 And it all actually move the Taurus to the plane. 05:06.190 --> 05:11.100 Now it's not obvious that it's happened until you actually turn off the first layer and you see all 05:11.110 --> 05:12.670 the Tauruses disappeared. 05:12.670 --> 05:13.990 So is the Taurus still selected. 05:13.990 --> 05:15.720 We can click this next one down. 05:16.510 --> 05:17.290 And there we go. 05:17.290 --> 05:18.490 It's gone orange. 05:18.490 --> 05:24.070 And that simply shows you when you've got an object selected this little orange blob shows you which 05:24.370 --> 05:27.130 layer that active object is on. 05:27.130 --> 05:28.930 So we can see down here the orange blob. 05:28.930 --> 05:35.890 And here in the lay a management tool that's we've got the plane selected and therefore it's the orange 05:35.890 --> 05:38.830 blob in the first layer because that's where the plane lives. 05:38.830 --> 05:48.220 If we right click on Taurus here or a doughnut we get the second orange if we select the lamp in our 05:48.220 --> 05:51.410 scene will that exists as an object on the first there. 05:51.410 --> 05:52.570 That's a good a good way. 05:52.570 --> 05:57.570 When you've got lots of things displayed simply eyeballing which layer it's actually on. 05:57.580 --> 06:02.150 So a couple of ideas for you with lasers you could put all your lighting on a certain layer. 06:02.200 --> 06:09.250 You could put all of certain things so in this instance I think we're going to have a rabbit on one 06:09.250 --> 06:09.530 layer. 06:09.530 --> 06:12.630 We're going to have grass on another layer and a tree on another. 06:12.700 --> 06:20.950 And perhaps if you guys decide to make your scene a little more involved a little more detailed then 06:20.950 --> 06:24.350 you can use multiple layers in order to do that. 06:25.050 --> 06:27.540 Okay guys it's challenge time. 06:27.540 --> 06:30.180 I'd like you to set up three layers. 06:30.180 --> 06:31.500 Now named the layers. 06:31.510 --> 06:34.930 Rabbit grass and tree respectively. 06:35.110 --> 06:41.940 And put some place holders on each layer representing the rabbits the grass and tree. 06:42.000 --> 06:43.880 Just use some primitives for the moment. 06:43.880 --> 06:44.970 Don't go overboard. 06:44.970 --> 06:49.530 These are just place holders so that I know that you understand how the legs are working. 06:49.560 --> 06:54.620 So then try switching between the layers and finally leaving all three on. 06:55.050 --> 06:57.610 So balls are video now and give that a go. 07:00.070 --> 07:00.750 Okay guys. 07:00.760 --> 07:01.900 Welcome back. 07:01.900 --> 07:08.050 Let's get three layers named rabbit grass and tree set up and the couple a place holders set on them 07:08.920 --> 07:11.670 so straight back over into blender. 07:11.740 --> 07:13.580 Well I don't like a doughnut some. 07:13.590 --> 07:15.970 I get rid of that. 07:16.600 --> 07:16.970 OK. 07:16.990 --> 07:18.580 Now the doughnuts has gone. 07:18.580 --> 07:22.670 Let's name our first layer rabbits. 07:24.280 --> 07:24.680 Oh. 07:24.760 --> 07:27.780 I have not spelt rabbit correctly that's a great start. 07:27.870 --> 07:34.290 And then we've got grass and then the final air here will be tree. 07:34.700 --> 07:39.810 And we may need more layers later depending on what we get up to but for the moment those three are 07:39.840 --> 07:40.710 great. 07:40.740 --> 07:43.270 So let's all are rabbits. 07:43.320 --> 07:44.670 So we've got the first layer here. 07:44.760 --> 07:48.680 Well I'm actually going to do a camera and lighting. 07:48.690 --> 07:51.540 I'm going to pop that on lighting. 07:51.660 --> 07:53.000 They will get a pop. 07:53.000 --> 07:53.900 My camera. 07:53.960 --> 08:00.840 I'm going to click on my camera over here and I'm going to move it to the fourth layer. 08:00.900 --> 08:05.630 There are also select the lamp and move that to the fourth layer. 08:05.640 --> 08:11.730 So that's those items moved off of Layer 1 and then we need. 08:11.730 --> 08:19.130 So we've got this ground plane here and we'll call it grass for the moment so we can set that up there. 08:19.170 --> 08:21.570 And we want that on the grass plain. 08:21.570 --> 08:26.010 So with that selected you can click this little circle here Rabbit. 08:26.040 --> 08:26.540 Okay. 08:26.580 --> 08:28.110 So turn everything else off. 08:28.110 --> 08:29.810 Are rabbits to begin with. 08:30.030 --> 08:33.390 Well we just put a cube in the scene to represent the rabbits. 08:34.700 --> 08:35.260 Okay. 08:35.270 --> 08:38.860 And finally free world trees kind of cylindrical. 08:39.080 --> 08:41.750 So we will make a cylinder. 08:41.880 --> 08:43.970 Now how about a cone it can be a Christmas tree. 08:43.970 --> 08:44.820 How about that. 08:45.050 --> 08:48.750 Okay so let's just undo that I want it moved. 08:49.490 --> 08:51.710 In the Z axis by just one. 08:51.750 --> 08:52.330 There again. 08:53.460 --> 08:56.580 And let's place that over here. 08:57.360 --> 09:00.720 Let's go and just test the render see how that looks. 09:00.810 --> 09:04.910 I think the camera is facing in a completely separate direction. 09:04.920 --> 09:08.990 Let's turn on all of the layers so we can see what's going on. 09:09.000 --> 09:12.540 In fact the camera's looking that way so I'll move it over. 09:12.720 --> 09:18.240 So that's render that image see what it looks like we've got our rabbit and tree behind it that looks 09:18.240 --> 09:18.990 great. 09:19.110 --> 09:22.290 And we've got all of our layers enabled. 09:22.410 --> 09:24.710 So let's go back to the 3-d view. 09:25.140 --> 09:27.830 Spin round here we've got all of our legs enabled. 09:27.870 --> 09:30.770 Let's just play turning them off so we can work on the grass. 09:30.780 --> 09:35.550 We can work on the rabbits we can work on the lighting if we wanted to do that and we can work on the 09:35.550 --> 09:36.050 tree. 09:36.120 --> 09:36.540 Brilliant. 09:36.540 --> 09:41.550 So we've got all of those things that are going to turn them all back on and that's brilliant. 09:41.550 --> 09:43.260 How did you guys get on. 09:43.260 --> 09:46.780 Did you manage to set up your scene with all of the various components. 09:46.890 --> 09:52.440 If you've got any extra ideas about how you're going to use layers please share them in the discussions 09:52.680 --> 09:55.420 and I will see you guys in the next lecture.
