WEBVTT 00:00.330 --> 00:07.840 Welcome to copying meche properties in this video you will learn how to copy attributes of a mesh object. 00:07.860 --> 00:14.700 See that this is actually really useful when you have lots of components for example that need the same 00:14.700 --> 00:22.050 material apply to them and understand that it is a destructive operation that is copying materials from 00:22.050 --> 00:26.360 one mess to another will overwrite a meshes current materials. 00:27.090 --> 00:31.150 So let's go explore this now and hop straight on over into blender. 00:32.110 --> 00:39.190 Hey welcome back over into blender so I've noticed as I open this up that's I've got a warning and that 00:39.190 --> 00:40.480 warnings just disappear. 00:40.480 --> 00:46.840 But what I can do is expose the window associated with the info header and we can see what's going on. 00:46.930 --> 00:51.940 So not much has happened here we can see that it's brought in its red library for the meche data and 00:51.940 --> 00:52.910 loads of other things. 00:53.080 --> 00:55.810 Oh got this red line here so we got a warning. 00:55.810 --> 01:02.740 That was the box that appeared a moment ago that the wall is missing from this particular file and I 01:02.740 --> 01:07.040 think I've read rename that and it's ended up being bald 0 0 1 now. 01:07.090 --> 01:13.150 It doesn't seem to have any impact on my 3D view so let's just have a look. 01:13.180 --> 01:18.220 Quick Rick look around our model and see if we can work out where this has gone wrong. 01:18.220 --> 01:20.740 So a wall pace for instance. 01:20.890 --> 01:26.530 And while all these blank areas here are war pieces Incidentally I have noticed that the wall pieces 01:26.590 --> 01:30.340 I've not applied the texture to both sides so it looks good here. 01:30.670 --> 01:36.040 But if that piece is flipped round it's still rather plain and I can see that on the inside of the church 01:36.040 --> 01:37.320 as well. 01:38.850 --> 01:44.450 Okay so I suspect that it's this roof area here that prehaps causing the problem. 01:44.450 --> 01:49.320 I remember that having a texture on it and it doesn't anymore and I can't remember removing that and 01:49.320 --> 01:52.790 it does say wall in the materials properties here. 01:52.830 --> 02:00.030 So in order to select linked materials i.e. other objects that may use the same material way as you 02:00.030 --> 02:03.030 probably already guess it's in the select menu. 02:03.030 --> 02:09.000 If we go down to the select menu and go to linked at the very top there we can see we can select anything 02:09.000 --> 02:13.270 that's got the same object data material data texture data et cetera. 02:13.410 --> 02:18.660 So if I go ahead and click on material we should find that that selects everything else that uses the 02:18.660 --> 02:20.520 same material. 02:20.550 --> 02:26.920 Now that it's done that I can go ahead and change the material for all of those so I can use the dropdown 02:26.940 --> 02:28.550 here and just change it. 02:28.560 --> 02:31.060 Let's say two linked wall. 02:31.080 --> 02:32.270 One that does work. 02:32.280 --> 02:33.580 One that's enough. 02:33.990 --> 02:38.080 Just going to save the file before I do any rendering and let's render that out. 02:38.160 --> 02:41.820 Now it's got a similar colour to the rest of the world in fact probably got a text on it. 02:41.820 --> 02:42.940 Yes it has. 02:43.140 --> 02:50.550 Okay so that's one way we can go about selecting everything that has the same linked property everything 02:50.550 --> 02:52.150 that shares something similar. 02:52.410 --> 02:57.200 But what about the ones that we want to make the same. 02:57.200 --> 02:59.980 So what we can do here is I can select. 02:59.990 --> 03:02.630 And then we go out of rendered mode against That's a bit quicker. 03:02.910 --> 03:10.260 I'm going to go ahead and select this roofline here and then go ahead and select the new roofline. 03:10.260 --> 03:15.830 Just here this silver arch way into the into the model itself. 03:16.380 --> 03:22.160 So then what I can do once I've selected them both holding down the SHIFT key there. 03:22.200 --> 03:22.710 There we go. 03:22.710 --> 03:24.380 Got them both selected. 03:24.480 --> 03:32.930 I can go ahead and go to object and make links so I can make links to the materials. 03:33.360 --> 03:39.600 Okay now all of this overwrites what they were using before so let's go and see what's just happened. 03:39.990 --> 03:42.610 So it's gone the other way round. 03:42.660 --> 03:49.080 It has taken the last selected items of the active selected and applied that to all the other selected 03:49.110 --> 03:50.330 objects. 03:50.430 --> 03:58.710 Everything that did have it has now gone backwards on both sides there so need to be careful about which 03:58.710 --> 04:00.390 way we select things. 04:00.390 --> 04:09.540 So if I wanted this material the top to share the same material as the wall for instance I would need 04:09.540 --> 04:11.260 to select the wall last. 04:11.310 --> 04:16.860 So could I go ahead and select the roof and the do it so I can see one selecting and must select these 04:16.860 --> 04:18.130 areas here. 04:18.410 --> 04:21.230 The little bits sticking out still don't know the name for that. 04:21.240 --> 04:24.100 And then finally I'm going to select a wall piece. 04:24.330 --> 04:29.790 Now I'm going to use a shortcut key which was control in L and select materials. 04:29.790 --> 04:35.370 Now when we go into rendered mode or material mode we can see that it's now using the same material 04:35.670 --> 04:37.500 as the wall piece. 04:37.500 --> 04:43.890 We can also see areas that are not using that so this area here for instance is a little triangle in 04:43.890 --> 04:45.150 the top corner here. 04:45.210 --> 04:51.580 We can go ahead select that select the wall pace and again control an L and select materials and now 04:51.580 --> 04:53.930 it will share the same material as before. 04:53.970 --> 05:00.690 So it's the last one that you're selecting the active selection that is going to be the source for the 05:00.690 --> 05:04.700 material to be copied to the other selected items. 05:04.860 --> 05:09.570 And that is incredibly powerful especially when working with a large object like this where otherwise 05:09.570 --> 05:15.120 I'd have to go round and select each one individually and that would be a real pain in the backside 05:15.120 --> 05:15.830 to do. 05:15.870 --> 05:18.420 So this is coming along really nicely now. 05:18.630 --> 05:24.700 I'm still not too sure on the roof pieces here and I certainly need to change the colour of that. 05:24.720 --> 05:28.310 But this is just a demonstration of how you can move those about. 05:28.300 --> 05:33.870 I think the roof does need to be a different colour than the set of the walls Otherwise it does look 05:33.870 --> 05:34.450 a bit odd. 05:34.620 --> 05:37.620 But of course now we have explored linking these objects. 05:37.620 --> 05:39.930 I've got a challenge for you. 05:39.930 --> 05:43.950 I would like you to explore different material choices. 05:43.950 --> 05:50.930 So just as a reminder here make sure you save your farm before exploring with any thing you do in blender 05:50.940 --> 05:56.820 that's potentially high or highly destructive such as changing materials about willy nilly. 05:56.850 --> 06:02.160 You may want to make a backup of your file or even you save as and progressed from there and give your 06:02.160 --> 06:04.230 file a version number. 06:04.230 --> 06:09.210 Explore different material options for your models in the scene see if you can come up with anything 06:09.510 --> 06:14.610 that's slightly different See how that affects your scene and remember to use the linking to quickly 06:14.610 --> 06:18.330 change a large number of objects at once. 06:18.330 --> 06:20.820 Pause the video now and give that a go. 06:23.090 --> 06:23.740 Okay guys. 06:23.740 --> 06:24.550 Welcome back. 06:24.700 --> 06:27.100 Let's hop back on over in a blender. 06:27.520 --> 06:34.000 So the first thing I'm going to do here is actually heed my own advice not divisive to save my work 06:34.220 --> 06:40.010 and I'm with a save as and I'm going to add staddon material. 06:41.640 --> 06:43.900 Exploration on the end. 06:44.190 --> 06:50.130 And then when we save as we find that we're working on that brand new file which is very powerful we'd 06:50.400 --> 06:55.920 say and don't want to make up our original far in list now opens up the realm for exploration and I'm 06:55.920 --> 07:01.830 going to change to material mode here so I can see a bit clearer what's going on as I move around the 07:01.830 --> 07:05.010 model without having to wait for it to render all the time. 07:05.100 --> 07:10.830 So one of the things that I can do here is literally select absolutely everything. 07:10.830 --> 07:16.690 Now when you do that it's the last selected object that becomes the active object. 07:16.710 --> 07:22.320 So if you had selected let's say one of these volts on the top or whatever you're working on and then 07:22.320 --> 07:25.020 pressed a twice it's still the active object. 07:25.020 --> 07:28.250 The original one that you selected and then it has everything on it. 07:28.260 --> 07:29.910 Now of course because of selected everything. 07:29.910 --> 07:37.860 If I go and apply the materials everything has that one material applied to it and that is interesting 07:37.860 --> 07:42.650 seeing that brick texture over the entire world itself. 07:43.020 --> 07:47.520 Now the question is Have we lost all of the properties all together. 07:47.520 --> 07:50.140 So these are sort of the explorations that you can do. 07:50.140 --> 07:52.490 So the answer there is yes we have. 07:52.620 --> 07:58.920 So even though we've not lost things like the displacement modifier and items like that we have actually 07:58.920 --> 08:06.480 lost the fact that it sets the material to use another texture to Alpher it out around the edge here. 08:06.480 --> 08:11.940 So it became more and more transparent my sky texture obviously hasn't changed at all that still the 08:11.940 --> 08:18.330 default sky if I go off to my world to hear you see I've picked sky texture and I've just left these 08:18.390 --> 08:19.720 as the faults here. 08:19.800 --> 08:23.970 So that is looking a bit more grey scale than it was previously. 08:23.970 --> 08:25.880 Obviously this doesn't change the geometry. 08:25.880 --> 08:31.410 However we can use this to change the geometry as well which is incredibly powerful. 08:31.410 --> 08:37.490 So let's undo that and our own blender has crashed. 08:37.500 --> 08:43.920 Now I didn't plan this but this is a warning that when you start mucking about with things it's very 08:43.920 --> 08:46.110 easy to crash blender. 08:46.140 --> 08:49.590 Someone's going to click reopen then see where we were before. 08:49.680 --> 08:54.600 Some will open up material exploration it's probably just where the save was before which was where 08:54.600 --> 08:56.250 I was going back to anyway. 08:56.340 --> 09:02.940 So let's say for instance I select this wall piece in the middle and then go ahead shift and select 09:03.180 --> 09:04.740 the window on top. 09:04.740 --> 09:12.390 I can go control in L and link object data and there we go I've got another window in place very powerful 09:12.390 --> 09:16.540 for swapping things in and out as well as changing materials. 09:16.830 --> 09:17.250 Brilliant. 09:17.250 --> 09:24.050 How did you guys get on did you do any modifications to your model after exploring different materials. 09:24.080 --> 09:29.540 If you have make sure you share your work in the discussions and I will see you guys in the next lecture.
