WEBVTT 00:00.330 --> 00:08.430 Welcome to using source control resetting in this video you will go over how to extract a previous version 00:08.460 --> 00:15.060 of your files and become aware that blend files are made up of linked files need to be accessed and 00:15.060 --> 00:17.950 restored in a slightly different way. 00:18.300 --> 00:21.080 So first of all let's have a look at source tree. 00:22.160 --> 00:26.260 Okay so in front of us I have some uncommitted changes. 00:26.270 --> 00:32.660 Now I have some unstaged files down here now this might look slightly different to how it looked before 00:32.930 --> 00:36.180 and that's because I've gone for a flat layout. 00:36.260 --> 00:44.240 So on the top of this particular section there is a little button that if you click you can change the 00:44.240 --> 00:45.410 view type. 00:45.410 --> 00:51.810 So I did have it on treeview like this but I was getting fed up of having to open these folders up in 00:51.820 --> 00:54.030 the hierarchy to see what was going on. 00:54.170 --> 00:58.730 So I've changed it to a flat list single column is absolutely fine. 00:58.730 --> 01:01.060 Tells me exactly what's going on and where things are. 01:01.220 --> 01:04.920 Although I can break it out so the path is separate to the others. 01:05.060 --> 01:07.370 So I've got I've changed the scene. 01:07.370 --> 01:12.650 The Gothic church I have a note that is a test for this lecture. 01:12.650 --> 01:18.670 This particular lecture that so that's been added to the working directory that we were in at the moment. 01:18.740 --> 01:24.340 I've got a couple of tests some in Dune stained glass windows few guys and a glass test blend file. 01:24.350 --> 01:25.290 I've been working on. 01:25.940 --> 01:32.870 Now if I want to go back in time I have to go to the next layer up and I've got all of my commit history 01:32.870 --> 01:33.560 going here. 01:33.560 --> 01:35.840 Going back and back and back in time. 01:35.900 --> 01:44.080 Now if I want to pick up a file from with in any of these historical events see this as a time line. 01:44.240 --> 01:48.980 If I want to go back in time to that say Here we go. 01:48.980 --> 01:57.240 G A P E 16 linking blend files I created a version of the Gothic church at that particular point. 01:57.290 --> 02:06.620 If I go and right click on that I can open the selected version and that will open up that particular 02:06.620 --> 02:10.860 file and we get a big long error message. 02:10.860 --> 02:14.500 Now this is because it contains linked items. 02:14.540 --> 02:21.020 If this was a non linked item so let's say the doorway or the archway the the items which were linking 02:21.980 --> 02:26.990 then we wouldn't have this error message but because we got linked items it causes us a problem so we 02:26.990 --> 02:28.750 just have a look at the blend file. 02:29.860 --> 02:35.830 Once the error message is gone we can see that pretty much everything has gone. 02:35.830 --> 02:39.150 Every bit of linked information and it's been replaced with empties. 02:39.160 --> 02:41.560 So you'd have a couple of choices at this point. 02:41.590 --> 02:49.270 You could relink formal by reimporting them into the scene and then replacing the appropriate empty 02:49.330 --> 02:54.970 with the right mesh and that would be a real pain if the scene well even with this relatively straightforward 02:54.970 --> 02:59.730 scene would be a real pain to do so we don't want to do that so what we need to do instead would linked 02:59.740 --> 03:07.270 files is actually go back in time completely and we can do that by the following notice at the top here 03:07.270 --> 03:12.970 the name is complete gobbledygook this is assets seeing Gothic church before and then a serial number 03:13.060 --> 03:16.360 that's coming from the database that everything stored in. 03:16.360 --> 03:23.800 But because this is existing within that database and not within the actual file structure itself the 03:23.800 --> 03:27.350 current file structure it doesn't know where anything else is. 03:27.400 --> 03:34.920 And this is perhaps where absolute links to our files would work better than relative links. 03:35.350 --> 03:42.100 But that aside what we need to do now is basically close that down because that's of no use to us. 03:42.190 --> 03:47.660 What we can do however is right click on there and check out this. 03:47.710 --> 03:53.260 This basically this part in history when we do that it gives us a warning. 03:53.410 --> 03:57.040 We can go ahead and click okay now. 03:57.460 --> 04:03.430 My file structure is exactly how it was when this comet was made. 04:03.430 --> 04:06.700 So if I go ahead and I can double click these as well. 04:06.700 --> 04:09.900 If I go ahead and open that up we can see that it works. 04:09.910 --> 04:11.400 Now that is pretty cool. 04:11.530 --> 04:19.530 At this point I can go in straightaway and go file save as and call it. 04:19.660 --> 04:23.220 I don't know it depends on what you're calling it recovered. 04:23.230 --> 04:29.530 Say I'd made some major mistake during my model or added a load of nonsense to it and I didn't want 04:29.530 --> 04:33.890 to go ahead and delete things and like when I could just go back to a previous happy state. 04:33.910 --> 04:38.960 My model so recovered gough Gothic church and a save that blend file. 04:39.310 --> 04:47.690 Now what I can do is go back to the source tree and go forward in time and go all the way back up here. 04:47.830 --> 04:55.960 So then I go to the last comet and check out that comet that pushes everything back to how it was before 04:55.960 --> 05:01.210 we went back in time to check everything else and when we go to are uncommitted changes if I just make 05:01.210 --> 05:04.010 this area a little bigger we will see that now. 05:04.030 --> 05:07.790 Waiting there for us is the recovered Gothic church blend. 05:07.810 --> 05:09.430 Now will we make our new comet. 05:09.430 --> 05:15.130 It will save that and we would have got back any potential date that we had lost or a model that we 05:15.130 --> 05:16.030 now want to take. 05:16.030 --> 05:18.070 Perhaps in a new direction. 05:18.490 --> 05:19.860 That is brilliant. 05:19.900 --> 05:22.260 Now I would like you to give this a go. 05:22.270 --> 05:24.420 In a very small challenge. 05:25.470 --> 05:33.230 I would like you to go back in time yourselves and restore a previous version of your interior scene. 05:33.240 --> 05:36.020 Balls of the air now and give that ago. 05:39.050 --> 05:39.660 Okay guys. 05:39.680 --> 05:40.680 Welcome back. 05:40.700 --> 05:45.640 Let's do that process again and I'll show you a couple of other nuances as we go. 05:46.860 --> 05:51.370 So we're back in the file structure itself down here. 05:51.480 --> 05:54.530 And I want to go back now. 05:54.570 --> 06:01.980 At this point in time I can see here that I made a commit that can change that contained the Gothic 06:01.980 --> 06:02.790 church. 06:02.850 --> 06:10.290 So if I want to go back before just one step before that I never committed I never made any change to 06:10.290 --> 06:16.110 the Gothic church so I can be a little confusing sometimes if I want to go back just one stage in that 06:16.110 --> 06:16.490 scene. 06:16.500 --> 06:20.350 I'd actually have to find when I change that. 06:20.400 --> 06:22.360 It wouldn't necessarily be there. 06:22.410 --> 06:24.260 What just going one back. 06:24.330 --> 06:26.040 So I'd go back here and go. 06:26.070 --> 06:27.230 No it's not in there. 06:27.240 --> 06:33.130 This is where the flats lay out really helps you know diving in and out of folder structures. 06:33.150 --> 06:36.110 So no it's not though I'm just looking for Gothic church blend. 06:36.150 --> 06:40.820 And as we go down here this is looking a bit bigger. 06:40.820 --> 06:41.800 And there we go. 06:41.820 --> 06:50.160 So I didn't change the actual scene itself didn't save that scene change anything in its way back here 06:50.160 --> 06:52.330 in gaap 20. 06:52.350 --> 07:00.060 So at that point I could go back and check out that area click okay here the folder changes I can double 07:00.060 --> 07:02.280 click and open up Gothic church. 07:02.280 --> 07:04.360 It should work when it opens up. 07:04.380 --> 07:06.640 I might need to tap into it. 07:08.650 --> 07:09.920 There we go. 07:09.940 --> 07:12.810 Just going to close that down and try double clicking that again. 07:12.820 --> 07:13.580 There we go. 07:13.580 --> 07:19.840 So that is how it was before I started adding all of the portals the light portals in in the previous 07:19.840 --> 07:20.480 lecture. 07:20.620 --> 07:26.530 And I might actually want to go back to this state if I don't want all of those portals in because it 07:26.530 --> 07:31.660 turned out that at the moment I've got enough light coming in that the portals are having very little 07:31.660 --> 07:34.170 effect other than slowing my scene down. 07:34.180 --> 07:42.760 So at this point I'm going to go file save as an unknown and go Gothic church before portals and then 07:42.760 --> 07:49.180 of course I can fork that and go off in a different direction with it so let's save that as the blend 07:49.180 --> 07:50.080 file. 07:50.080 --> 07:56.140 Now remember at this point I'm going to have to go back to the committee that I made or the most recent 07:56.140 --> 08:02.920 committee in this case and I should have in uncommitted changes a list of items. 08:02.980 --> 08:07.480 And here we go rigi off recovered gough at church someone done and got it shown. 08:07.610 --> 08:13.970 There he is back in camp and Gothic church before the portal. 08:14.080 --> 08:17.010 Well before light portal's I could have been a bit more descriptive. 08:17.110 --> 08:23.850 So then I can go and stage all of my file so I don't lose any of the recovery that I've just done. 08:23.920 --> 08:26.890 And of course I'm going to call this one appropriately. 08:27.130 --> 08:29.780 And there we go I'm going to make my commit. 08:30.190 --> 08:31.990 And everything's done okay. 08:32.020 --> 08:32.520 Brilliant. 08:32.530 --> 08:40.240 I hope you guys restored a previous version of your interior scene and I will see you guys in the next 08:40.240 --> 08:40.920 lecture.
