WEBVTT 00:00.420 --> 00:05.510 Welcome to walking and flying around your model in this video. 00:05.520 --> 00:13.050 You see how our scene looks and feels by walking around it using the fly and walk mode. 00:13.050 --> 00:16.310 Show you how to see the scene in unity. 00:16.410 --> 00:21.820 Understand that I am only using unity to keep the iterations quick and simple at this early stage. 00:22.020 --> 00:25.440 And that unity is optional. 00:25.440 --> 00:27.600 Anything external to blend that we do. 00:27.600 --> 00:31.500 You can watch to see how it works and how it is coming across. 00:31.500 --> 00:34.740 You can see the impact of what's going on. 00:34.740 --> 00:40.440 You'll gain a better understanding of external programs when doing this and Occasionally you may want 00:40.440 --> 00:46.800 to work with external programs whether it be art packages or other 3D modelling packages. 00:46.800 --> 00:52.350 Now join in if you have unity installed and are interested in learning more about this particular prototyping 00:52.350 --> 00:53.370 method. 00:53.490 --> 00:56.200 So let's hop straight on over in a blender. 00:57.620 --> 01:02.990 Right now that we're back in our church in the moment we've been manipulating this by simply using the 01:02.990 --> 01:07.010 mouse scrolling up and down holding down shift and panning across. 01:07.190 --> 01:08.780 But that has its limitations. 01:08.780 --> 01:14.990 For example it's very easy as we've all experienced already to run out as zoom when you can't go any 01:14.990 --> 01:20.750 further and you have to refocus what you're looking at and we can get around that by hitting shift in 01:20.900 --> 01:27.470 F that enables flight mode and we can start using the W A S and deed keys. 01:27.470 --> 01:34.520 If you've ever played any first person shooters to move around our scene so we can strafe like panning 01:34.540 --> 01:39.240 out with a Andy w moves forward and s moves back. 01:39.280 --> 01:43.500 Now this looks like a painfully slow speed that we're moving at at the moment. 01:43.610 --> 01:49.610 But you can speed that up with your scroll wheel or page up page down and we can see that as I am on 01:49.610 --> 01:54.890 a macheath SOME scrolling down I can pick up speed and whiz around the model. 01:54.890 --> 02:00.710 Of course we've got my little mannequin Hindi here for scale it helps to really set the scene and I 02:00.710 --> 02:07.340 can see that walking around I can adjust this so I get a much better feel and well that's looking pretty 02:07.370 --> 02:08.100 good. 02:08.430 --> 02:14.720 Okay what else can we do here where we can turn gravity on and off by hitting the tab key which enables 02:14.720 --> 02:17.990 us to walk on the surface of our model. 02:17.990 --> 02:19.220 And when you hit the spot. 02:19.230 --> 02:20.010 Oh there we go. 02:20.010 --> 02:24.490 I've fallen away so that's why one of the reasons why you wouldn't necessarily want to. 02:24.490 --> 02:25.470 But gravity. 02:25.640 --> 02:27.810 I just use the scroll to back up here. 02:27.890 --> 02:31.420 But wait a minute there's a quicker way of a whizzing about. 02:31.430 --> 02:33.090 See that little cross hair in the middle. 02:33.110 --> 02:39.590 Well if I put that on a particular part of my model and then press the space bar we what hop to that 02:39.590 --> 02:46.250 part of the model so it's very easy to quickly hop around if I target my mannequin and go bang straight 02:46.250 --> 02:46.920 there. 02:47.120 --> 02:53.390 Very powerful for skipping around large models and we can see there are further controls on the bottom 02:53.390 --> 02:54.240 of the screen. 02:54.260 --> 03:03.190 Now when you come out of our flying mode it with the right mouse button it goes back to the previous. 03:04.060 --> 03:06.350 Viewpoint before you started flying around. 03:06.400 --> 03:12.460 Now you may of course want to fly into your model and to a particular place in the model to have a look 03:12.460 --> 03:18.040 at it and keep that we can do that with the left mouse button enter as well. 03:18.040 --> 03:18.700 And there we go. 03:18.700 --> 03:20.050 We've got that viewpoint. 03:20.050 --> 03:26.170 It's incredibly powerful for moving about a model especially one that's getting quite large and potentially 03:26.170 --> 03:27.910 quite complex. 03:27.910 --> 03:34.150 And of course we can hit shift in F again and pressed space to move to the tower and go up to the top 03:34.150 --> 03:38.120 of a tower and look down a lord over everybody beneath us. 03:38.170 --> 03:39.220 Brilliant. 03:39.460 --> 03:44.980 Okay so I don't want this viewpoint so I'm going to right click to go back to my previous one which 03:44.980 --> 03:48.910 is a much better viewpoint of the rest of the church and the Ancients way over there. 03:48.910 --> 03:52.560 And let's go have a look at what this looks like in an external package. 03:52.560 --> 03:55.110 I'm going to be using unity for this example. 03:55.180 --> 03:56.670 Now a quick side note here. 03:56.670 --> 03:59.690 Unity does support opening up blend files. 03:59.860 --> 04:07.810 How ever what it's really doing is in the background it's opening up a blender is exporting the model 04:07.810 --> 04:13.300 as an F X and then and only then is it opening it up. 04:13.330 --> 04:15.490 So it's quite a clean way of doing it. 04:15.490 --> 04:22.300 But if your model starts to get complex that can really bog down unity and I've had it spend at 15 to 04:22.300 --> 04:26.790 20 minutes trying to open up every time and that's just unmannered manageable. 04:26.800 --> 04:31.240 We can't wait minutes and minutes and minutes just to open up a program that's there's nothing lean 04:31.240 --> 04:32.440 about that. 04:32.500 --> 04:38.200 So what I'm going to do in this case and one of the other things to make sure that we do is if we ever 04:38.230 --> 04:44.100 export our model at the moment if we just export as an FBI X we'll get all of the parts as well. 04:44.100 --> 04:53.740 So we turned on the second layer here as well we'll end up with whatever we get these other additional 04:53.740 --> 04:56.810 parts and the extra manequin they're coming across as well. 04:56.830 --> 05:02.890 So we need to make sure that we're only exporting the bits that we want to export so we can select individual 05:02.890 --> 05:04.970 items or the entire lot. 05:05.020 --> 05:09.480 In this case I'm going to import the entire lot and walk around it. 05:09.760 --> 05:15.220 Although you may wish to reconstruct this in an external package as well in which case you just export 05:15.220 --> 05:21.160 the parts and then give full control to the level designer or whoever to put all the parts together 05:21.160 --> 05:22.380 how they deem fit. 05:22.390 --> 05:28.390 Because obviously if I give someone a big model like this it can be quite annoying to have to deconstruct 05:28.390 --> 05:33.220 it first to reconstruct it how you like but this is a great example about how all those pieces fit together 05:33.580 --> 05:38.740 a bit like when you buy some Lego you get a picture of what you should be making and then a quiz you 05:38.740 --> 05:41.060 ignore that and go and make some other coarse stuff. 05:41.530 --> 05:46.510 So now what we can do is just make sure that the things we want selected are the ones that we're going 05:46.510 --> 05:52.030 to export some of the totally ignore the parts bits but select all of the other empties. 05:52.110 --> 05:58.600 But going to select these empties whilst holding down control so it selects all of the meshes underneath 05:58.600 --> 05:58.930 as well. 05:58.930 --> 06:01.550 So I'm going to want to select that. 06:01.570 --> 06:03.200 And then I'm going to hold down Shift. 06:03.220 --> 06:09.590 Add to that selection and select the other bits in our scene some skin to go down here and select those. 06:09.640 --> 06:11.250 I don't need the lampl camera. 06:11.260 --> 06:12.990 They are completely irrelevant. 06:13.000 --> 06:18.270 Whenever I'm exporting cars they are controlled and have settings really only in blender. 06:18.640 --> 06:26.230 So now that I've done that I can go to file an export and go to FBI X. That's a standard one for most 06:26.230 --> 06:30.860 packages if you're doing 3D printers then it'll be S T L as a standard one. 06:30.940 --> 06:35.760 And obviously there are some other ones that you'll notice here if you're working with Sketchup colada 06:35.770 --> 06:40.180 is the one it supports doesn't support sbx and this of course natively supports 3D. 06:40.210 --> 06:41.890 S Max as well. 06:41.890 --> 06:47.080 Someone to click on FP X and it's almost ready to save you can see I've already saved it in the past 06:47.350 --> 06:52.450 but one of the important things here and pretty much all we need to do at this moment is put a tick 06:52.450 --> 07:00.670 in the selected objects box and then we know when we export in a few seconds time will only get those 07:00.670 --> 07:04.350 selected object and not everything that's in our scene. 07:04.510 --> 07:08.640 Now we're going to go ahead and click on export now a word of warning. 07:08.650 --> 07:14.850 It doesn't ask you Are you sure if you want to overwrite it will just overwrite the file. 07:14.890 --> 07:18.540 It's got the same file name or you've accidentally clicked on something else. 07:18.560 --> 07:19.890 So do bear that in mind. 07:19.890 --> 07:21.110 There is no going back now. 07:21.180 --> 07:23.380 I've overwritten that file that was No. 07:23.380 --> 07:25.380 Are you sure which is odd. 07:25.390 --> 07:26.240 Was so used to. 07:26.260 --> 07:28.450 Are you sure as an undoing. 07:28.510 --> 07:31.270 And the computer guiding us along but it doesn't do that. 07:31.510 --> 07:35.530 So let's go have a look at how this opens up over in unity. 07:36.040 --> 07:42.610 Okay so I have set up my scene over in unity of imported the Gothic church and I've imported some standard 07:42.610 --> 07:49.270 stuff so I can have the first person androzani going to go ahead and hit play and then I should be able 07:49.270 --> 07:50.500 to walk around my scene. 07:50.530 --> 07:56.290 So going to make this bigger for your you guys area go and this gives a much better impression of the 07:56.290 --> 07:57.900 actual scene as we walk around it. 07:57.910 --> 07:59.130 Hello mannikin. 07:59.230 --> 08:03.680 Now these yellow patches here don't worry about those are just reflecting the ground man. 08:03.760 --> 08:08.200 It's directly parallel with the ground it's going to do see is happening there and to some extent under 08:08.200 --> 08:08.890 the arches. 08:09.040 --> 08:11.590 I don't have an oar I've actually walked to have a door that was very good. 08:11.590 --> 08:17.060 I was going to say I dont have any colliders So while I do on the floor so I dont fall through by there 08:17.080 --> 08:21.010 on the walls or anything like that at the moment so I can go in and out of the model. 08:21.050 --> 08:26.380 This is really good for seeing how its going to work so I can already see some problems and its good 08:26.380 --> 08:28.410 that I can see problems at the moment. 08:28.410 --> 08:29.850 Big cars. 08:30.070 --> 08:33.660 Well I can fix them sooner rather than later. 08:33.820 --> 08:38.260 And here we see this one's working and that's because it's a solid model so I've also identified at 08:38.260 --> 08:47.680 this point that when I moved these into the scene and indeed all of these volts the ceiling pieces the 08:47.710 --> 08:53.830 modifier the solidify modifier did not link as well so I'll need to set that up again on them all. 08:53.860 --> 09:00.880 I can also see around here whereas this bit here it looks like there's a piece misaligned idea bad construction 09:00.880 --> 09:01.020 there. 09:01.020 --> 09:04.150 Or is it a secret panel to a secret area of the church. 09:04.150 --> 09:09.210 Who knows but we can start to see here that this this is feeling right it's feeling pretty epic it's 09:09.220 --> 09:11.640 feeling big is not feeling too big. 09:11.650 --> 09:15.090 This is a one point six meter mannequin. 09:15.100 --> 09:19.920 It's actually a very handsome chap it's modelled on myself hergé. 09:20.170 --> 09:25.600 So this is great because we get to experience how it is looking and how it feels. 09:25.600 --> 09:30.070 By just walking around it now obviously because these are made out of modular parts. 09:30.070 --> 09:35.470 The game designer or yourself if you're wearing multiple hats can now start filling about with the layout 09:35.860 --> 09:40.730 inside the game engine or wherever else you're working with straightaway. 09:42.000 --> 09:43.550 Okay quick challenge for you guys. 09:43.550 --> 09:49.610 I'd like you to explore your model move around your model and get fit I have a better feel for the space 09:49.640 --> 09:51.380 that you are creating. 09:51.380 --> 09:57.500 Remember to make any alterations immediately working lean and walk around again and test those alterations. 09:57.500 --> 10:02.600 Now optional for those with unity or another game engine or another external package import your model 10:02.660 --> 10:05.760 and walk around it or fly around it there too. 10:06.080 --> 10:09.650 If the airport has problems remember that is a good thing. 10:09.710 --> 10:15.860 Were being lean about this and taking it to one of the N stages that we want very quickly to make sure 10:15.860 --> 10:21.290 that there aren't any glaring problems so balls a video now give that a go. 10:21.290 --> 10:25.790 I've already identified some problems with my model so I'm going to go and fix that. 10:25.910 --> 10:28.950 But I will see you guys in the next lecture.
