WEBVTT 00:00.720 --> 00:02.600 Welcome back it's Ben tristam with you. 00:02.610 --> 00:04.920 I'm going to be talking about exporting your model. 00:05.160 --> 00:08.660 So in this video we will tidy our folders for future access. 00:08.940 --> 00:15.930 Export our models as an sbx file import the sbx into both unreel and unity game engines. 00:15.930 --> 00:20.420 Don't worry you don't need either of those installed I just want you to see the process and then we 00:20.460 --> 00:26.440 briefly talking about opening blend models in unity 5 and about exporting textures and materials. 00:26.460 --> 00:30.990 So firstly this is the folder structure it's a very real folder structure that Michael's ended up with 00:31.380 --> 00:35.070 and I just want to talk through how we may think about organising this for the future. 00:35.430 --> 00:37.770 So firstly we have a couple of things here. 00:37.830 --> 00:40.850 The diffuse shader example and this brick. 00:40.850 --> 00:45.690 Q But blend that were used in the production but we don't need now I think a good practice is as Michael 00:45.690 --> 00:48.660 has really started to put those in an archive folder. 00:49.350 --> 00:54.630 Next up we have a couple of renders These are image renders of the actual scene would make sense perhaps 00:54.630 --> 00:56.160 to put them in a folder called renders. 00:56.160 --> 00:57.150 It's entirely up to you. 00:57.150 --> 01:00.830 But the concept is that we are just tidy with our files. 01:00.870 --> 01:03.530 This is your section assets specially for the course. 01:03.570 --> 01:07.030 So then we should be left with six different pieces in chess. 01:07.050 --> 01:07.910 The Bishop. 01:08.920 --> 01:10.840 The base can go into the archive. 01:10.840 --> 01:16.000 The king the night the queen and the queen Mark to Songa archive the first version of the Queen. 01:16.000 --> 01:22.240 So we're clear on what the current version is and the rook were just missing the porn which is probably 01:22.240 --> 01:22.900 in the archive. 01:22.900 --> 01:25.590 Here it is. 01:25.620 --> 01:30.510 And now at the top level we have the scene and then a lot of things that are collectively the pieces 01:30.520 --> 01:32.040 so I'm just going to make. 01:36.260 --> 01:38.740 Pieces before append. 01:38.890 --> 01:42.940 Now these are the pieces before they were appended into the main chess scene. 01:42.940 --> 01:49.030 Any changes that have been made to these pieces inside the chess scene blend file will not be propagated 01:49.030 --> 01:50.150 into the Chessy. 01:50.260 --> 01:55.180 Okay so just understand that these pieces exist in two places in the hierarchy of the chess scene blend 01:55.180 --> 01:58.610 file but they also exist as individual pieces here. 01:58.630 --> 02:01.610 These are very helpful for importing into things like unity. 02:01.660 --> 02:02.440 So let's look at that. 02:02.440 --> 02:06.960 Now let's go to for example the bishop sets the first one in the list. 02:07.000 --> 02:07.740 Here's the bishop. 02:07.770 --> 02:13.660 Note on your bishop that you had a Q here that we hid because we used it for shaping the head of the 02:14.290 --> 02:15.560 poor as the bishop. 02:15.790 --> 02:23.340 So what we need to do is when we export this as an FBI file I want to show you what happens in unity 02:23.350 --> 02:29.380 so I'm just gonna put this in my downloads and then I'm going to go over to unity which you don't need 02:29.380 --> 02:29.750 in still. 02:29.740 --> 02:31.170 I just want to show you what happens. 02:31.180 --> 02:37.250 Some of the things that you may find when you're working with a game designer actually turn up happening. 02:37.480 --> 02:42.010 They may say or I like the bishop but it's got this big things sticking out of it and there are no materials 02:42.010 --> 02:44.860 on it so materials won't come across. 02:44.860 --> 02:49.990 I'm afraid not your texture's Anyway you make it the base colour come across room from blender but you 02:49.990 --> 02:55.280 won't have the actual textures like the wood texture and the other thing is this cube is still here 02:55.330 --> 02:57.670 as a subobject of the bishop. 02:57.670 --> 03:02.230 Now I can just delete it in unity and it's gone. 03:02.230 --> 03:05.260 But of course if we rueter reimport that model it would come back. 03:05.260 --> 03:08.820 So your options as a blender artist are to delete it here. 03:08.830 --> 03:14.950 But then you know you may want to keep this form for future purposes or just communicate with the unity 03:14.950 --> 03:19.840 developer and say hey there's going to be this extra cube just delete it and create yourself a new well 03:19.900 --> 03:23.500 is not up to you to tell them what to do but they would do something like create a new prefab. 03:23.500 --> 03:24.070 Doesn't matter. 03:24.070 --> 03:25.830 Those are there's a unity details. 03:26.350 --> 03:30.810 But the point is that they can safely modify it as long as they understand what's going on. 03:30.850 --> 03:37.270 It's hidden inside blender but is still an object when it's exported as an f b x and the same thing 03:37.270 --> 03:41.950 would happen if we opened this as a dot blend file in unity we'd have exactly the same issue. 03:42.160 --> 03:45.730 Right now I just wanna show you a different engine which is the unreel engine. 03:45.730 --> 03:53.230 Let's just import the same piece into the unreal engine so if I just import over here the bishop. 03:53.840 --> 03:58.730 One of the things with unreal is the scale is very different so when I import using the default import 03:58.730 --> 04:04.310 settings which I actually don't want to use I would probably want to set this to point nought one but 04:04.340 --> 04:10.500 if I use the default settings then the Bishop will be very large and unreal towering into the sky. 04:10.700 --> 04:14.980 And of course it will still have this issue with the cube sub element in it. 04:14.990 --> 04:19.430 Again you may need to do a special export for people deleting that element because hiding it will do 04:19.970 --> 04:25.100 alright so the take home from Blender is that these hidden elements like cubes will appear in the sbx 04:25.130 --> 04:29.780 and you may need to either delete them or communicate with the person youre handing it to to make sure 04:29.780 --> 04:32.170 that they understand how to handle that. 04:32.240 --> 04:33.060 Great. 04:33.080 --> 04:37.130 So another thing to tell you is you can open up blend files directly in unity. 04:37.130 --> 04:40.050 If youre using unity you would know that and that works just fine. 04:40.070 --> 04:43.370 You can end up with a rotation issue with simple models. 04:43.370 --> 04:48.470 So let me just show you that so that you're aware if we take a simple model like a blender porn for 04:48.470 --> 04:49.260 example. 04:51.700 --> 04:52.810 Let it open. 04:54.890 --> 04:55.370 Look. 04:57.330 --> 04:57.690 There it is. 04:57.690 --> 04:58.460 There is a rook. 04:58.470 --> 05:00.180 Now this rook has a single mesh. 05:00.200 --> 05:02.370 There's only one mesh object in the hierarchy. 05:02.370 --> 05:04.230 This is when we get a problem with unity. 05:04.230 --> 05:07.630 Let me show you what happens if I directly open this rook. 05:07.650 --> 05:08.940 In unity now. 05:08.960 --> 05:12.340 Okay so I go to important new asset. 05:13.430 --> 05:14.790 I go find the rook. 05:16.050 --> 05:17.400 Pop it into unity. 05:18.870 --> 05:20.460 And into the scene. 05:20.460 --> 05:21.150 Now there it is. 05:21.150 --> 05:25.680 And it looks like it's okay in the scene the warning sign in Unity is that the rotation has come with 05:25.680 --> 05:27.000 a minus 90 on the X. 05:27.000 --> 05:30.990 Now look what happened this is sort of weird bug you may you may have reported I'm just going to pop 05:30.990 --> 05:35.320 a camera a light into my scene because it's rather dark that's better. 05:35.370 --> 05:39.900 Now when I try and rotate my rook around the x axis it's all fine. 05:39.900 --> 05:44.360 X is the red axis in unity when I try and rotate it round the y axis it's all fine. 05:44.370 --> 05:48.810 But look at this when I try and rotate the z axis it behaves the same as if I was rotating round the 05:48.810 --> 05:51.450 Y that will cause a lot of problems. 05:52.170 --> 05:55.500 There's a simple way to solve that two simple ways to solve that from Blender. 05:55.500 --> 05:58.000 One is to give your game designer an F be X.. 05:58.140 --> 06:04.040 If I exported this as an F be X as we did before with default settings it will be fine. 06:04.050 --> 06:09.930 Another way to solve this is if you want to work with the blender workflow is actually to add yourself 06:10.440 --> 06:11.750 in object mode. 06:13.520 --> 06:14.110 A. 06:14.880 --> 06:16.190 Empty plane. 06:16.220 --> 06:17.250 Axis. 06:17.520 --> 06:19.350 And that's just sits down here at the origin. 06:19.380 --> 06:21.190 Inside the rook file. 06:21.240 --> 06:23.110 If I then save that. 06:24.240 --> 06:29.190 So here's the rook having saved it with these axes So let's pop that into unity. 06:29.280 --> 06:33.660 Now it looks up right in the preview and when I put it in the scene we don't have this funny rotation 06:33.660 --> 06:36.760 in X and all the rotations behave properly. 06:37.150 --> 06:39.800 Okay so there's a useful tip for you in blender. 06:39.930 --> 06:44.070 If you've only got a single mesh meshes only happens this bag with single meshes when you have more 06:44.070 --> 06:45.730 than one mesh like the rook. 06:45.740 --> 06:46.920 I like the bishop. 06:46.920 --> 06:47.830 This doesn't happen. 06:47.880 --> 06:50.390 Just put a plain axes in and that will solve the problem. 06:50.390 --> 06:56.010 You can work directly in unity with a blend file then so the final thing to say is as I as I briefly 06:56.010 --> 06:56.360 mentioned. 06:56.370 --> 06:59.580 Is the materials don't get covered a cart carried across. 06:59.580 --> 07:05.360 So if we were to look at the full chess scene here and bring that into unity. 07:06.310 --> 07:10.530 It's going to take a while to import because it's a much bigger model than some of the other models. 07:10.870 --> 07:14.110 I'm going to delete the rooke's in the scene and pop the chessboard in. 07:14.140 --> 07:16.300 All looks good in unity but it's all flat. 07:16.300 --> 07:22.930 You see there's no textures on the side of the board here no wood texture and the subject of actually 07:23.380 --> 07:24.700 what we call u v. 07:24.700 --> 07:31.540 Unwrapping your model over in blender your full chest scene model and exporting those textures is something 07:31.540 --> 07:35.290 we'll cover it in a couple of sections time because it's a little more complicated so I hope that's 07:35.290 --> 07:38.930 been useful given you some experience of how these things are going to end up in other packages. 07:39.130 --> 07:44.350 Remember generally use sbx with default settings that will be fine if you are going to use unity to 07:44.350 --> 07:48.730 open blender files directly put a plain axes into any model where you've got a single mesh and that 07:48.730 --> 07:50.830 will solve your rotation issues. 07:50.830 --> 07:51.540 And yeah. 07:51.580 --> 07:52.320 So you say.
