WEBVTT 00:00.870 --> 00:06.680 Welcome to a profile based modelling using mesh objects in this video. 00:06.680 --> 00:14.700 You use the array modifier to repeat a mesh objects along the length of a curve will then deform the 00:14.700 --> 00:21.710 array using the same curve data and hopefully end up with some pretty awesome results. 00:21.720 --> 00:24.570 So let's go hop on over in a blender. 00:24.930 --> 00:27.330 Hello everybody and welcome back over into blender. 00:27.330 --> 00:31.840 The first thing you might notice here is I'm back on my p.c SO is me Michael from the future. 00:32.130 --> 00:37.380 And the other thing to mention here is that this particular door that we're about to work on doesn't 00:37.380 --> 00:40.310 have the curve profile that we set up in the last lecture. 00:40.440 --> 00:44.370 But that doesn't matter because we can do everything we need to do with what I've got in front of me 00:44.370 --> 00:44.740 here. 00:44.850 --> 00:49.470 Or you could even use your curved profile to work office as well a little mini challenge if you want 00:49.470 --> 00:51.710 to go off and do that later on. 00:51.720 --> 00:57.450 So the first thing we need to do is think about what we're going to do in terms of duplicating the information 00:57.450 --> 01:01.950 we have in front of us here because I could just go ahead duplicate the entire mesh objects in front 01:01.950 --> 01:04.640 of me and then go and delete the geometry. 01:04.640 --> 01:12.120 I don't want or I could go into that mesh object itself by going into edit mode find the bit of geometry 01:12.120 --> 01:17.580 I want to select in this case it will be this bottom face here although there is something odd going 01:17.580 --> 01:20.700 on the bottom face I'm not sure what is going on there. 01:20.730 --> 01:22.260 It seems a bit crooked. 01:22.260 --> 01:27.090 In fact it looks like there's still sivers doubles over there you know. 01:27.240 --> 01:30.380 Yes it's it's done something very weird with that profile. 01:30.420 --> 01:33.960 I'm going to delete that bottom face at the moment and then sort that out. 01:33.960 --> 01:39.330 Now this will obviously didn't want to do that I just to delete the face itself's X and then delete 01:39.360 --> 01:40.180 the face. 01:40.260 --> 01:42.310 So there is some rule. 01:42.380 --> 01:45.540 And so you'd lose geometry and here perhaps there might be. 01:45.570 --> 01:49.550 I'm not entirely sure thing I'm trying to select the main axis there. 01:50.500 --> 01:52.590 So we can select the age group running around. 01:52.600 --> 01:57.570 There seems to be a break in edge loops around there when to select everything here remove doubles. 01:57.580 --> 02:00.120 Nothing there no increase the merge distance. 02:00.130 --> 02:06.040 Not that much but ever so slightly and just make sure that the profile remains intact which I think 02:06.040 --> 02:07.070 it has done. 02:07.270 --> 02:12.160 Yes I think there might have been some geometry that was very close to itself anyway. 02:12.220 --> 02:13.740 I'm happy with that now. 02:13.760 --> 02:18.340 And what I really want is this bottom edge running ran and we see excellence being selected all at once 02:18.340 --> 02:18.770 there. 02:18.820 --> 02:22.370 So at some point a duplicate a bit of geometry moved it to one side. 02:22.480 --> 02:29.290 But now I've got that bottom edge loopier I can both fill it in and we can see that one of the issues 02:29.290 --> 02:33.820 that it makes there's with the subdivisions surface model the fire as she brings it all together. 02:33.970 --> 02:38.770 So finally I'm going to increase the mean crease so doesn't do that. 02:38.770 --> 02:44.890 Now that that's done I can grab this bottom face and duplicate it will shift and day and then press 02:44.890 --> 02:51.730 the P key to separate it by selection and it will generate a new mesh object with the same name as before. 02:51.730 --> 02:52.450 That's fine. 02:52.540 --> 02:54.390 Only change that name to door profile. 02:54.410 --> 02:59.890 So this is going to be a mesh profile that we're going to use before we do anything else. 02:59.910 --> 03:04.780 There are a couple of modifiers attached to it so let's go ahead and remove those and then hide. 03:04.870 --> 03:06.240 Profile one. 03:06.250 --> 03:11.440 So we've got our starting point here that we're going to build up a bit of a an example with. 03:11.800 --> 03:17.650 So let's go ahead into edit mode and select that face and extrude it up almost flip around to the front 03:17.650 --> 03:22.270 view I mean orthographic mode here so I can extrude that up by let's say that amount. 03:22.270 --> 03:27.610 Now we can see straightaway that this isn't going to work as I intended because the normals are flip 03:27.610 --> 03:34.890 so let's go select everything and then control an N to flip those normal so that's a great start. 03:34.900 --> 03:39.540 The next thing I'm going to do is background to the front view with the number pad number pad number 03:39.580 --> 03:40.450 one in this case. 03:40.560 --> 03:43.140 And I am going to duplicate this mesh that I've generated. 03:43.170 --> 03:49.240 Fix it to the x axis and then just lift it up with enough space for two hours of fake mortar or a gap 03:49.240 --> 03:54.430 in the brick work that's going to add a bit of shadowing and then I'm going to zoom around or not zoom 03:54.430 --> 03:58.810 Let's move around here select a couple of these faces that I want to pull out. 03:58.920 --> 04:01.100 Now I'm not just going to pull them out. 04:01.280 --> 04:03.010 Actually that might work in home. 04:03.070 --> 04:05.880 I can just pull it out like that and be done with it. 04:06.040 --> 04:06.300 Yeah. 04:06.310 --> 04:06.720 Okay. 04:06.820 --> 04:08.790 That will do for the purposes of this exercise. 04:08.790 --> 04:13.580 I was thinking of extruding rather than just moving but that looks all right there. 04:13.720 --> 04:17.950 Now a couple of options we've got with these corners here because we've got some odd shadowing going 04:17.950 --> 04:18.340 on top. 04:18.340 --> 04:25.310 Now the odd shadowing of course is is caused by the fact that there these are in ons here and it's not 04:25.410 --> 04:29.760 what is trying to smooth it the best it can but it doesn't really know how. 04:29.770 --> 04:31.660 So we can bevel this edge around the top. 04:31.660 --> 04:34.070 We could make some loop cuts closer to it. 04:34.090 --> 04:36.420 It's entirely up to you this very top face here. 04:36.430 --> 04:40.120 We're not going to see any way any shading artefacts around. 04:40.170 --> 04:41.440 We'll deal with that later. 04:41.500 --> 04:43.100 If there is indeed an issue. 04:43.420 --> 04:44.680 So we've got our meche object. 04:44.680 --> 04:50.500 Let's go back into object mode and add in an array modifier because we want this to repeat itself. 04:50.650 --> 04:55.910 So the array modifier is under the generate column so it's right at the very top array. 04:56.170 --> 04:58.190 And it's going the wrong way. 04:58.450 --> 05:01.930 Of course we can increase the counts and that's great and looks like a brick wall it's going the wrong 05:01.930 --> 05:02.130 way. 05:02.130 --> 05:08.470 So let's turn relative offsets on the x direction to zero and we probably want it on the z direction. 05:08.470 --> 05:09.030 Excellent. 05:09.040 --> 05:14.590 And I'm going to zoom in here because one of the issues will be is that it butts one object up against 05:14.590 --> 05:18.220 the other and we don't want that we want a little gap between the two. 05:18.220 --> 05:20.780 So this is going to need to be something like 1 point. 05:20.800 --> 05:27.180 No that's too much too little I'm going to hold down Shift to move this in a much more controlled manner. 05:27.370 --> 05:28.480 Let's say about there sir. 05:28.530 --> 05:30.550 Oh port o points. 05:30.660 --> 05:33.760 Not the rry of a blender unit up. 05:33.840 --> 05:34.420 So there we go. 05:34.420 --> 05:35.170 Perfect. 05:35.170 --> 05:37.020 Now if we increase the account number. 05:37.030 --> 05:41.050 Oh dear that's that's no good is it it's going in a random direction. 05:41.260 --> 05:42.790 Now we want to control this. 05:42.790 --> 05:48.960 We need to fit to something else at the moment it's being fitted to a fixed count to ten of them. 05:49.030 --> 05:54.580 If I change it to fit courval Fit a length Well we dont have a length for it to fit because I dont know 05:54.580 --> 05:55.960 the length of this curve. 05:55.960 --> 06:00.370 But what we can do is select fit curve and we need a curve for it to follow. 06:00.370 --> 06:02.200 Do we have a curve at the moment. 06:02.200 --> 06:03.340 Unfortunately we dont. 06:03.340 --> 06:04.940 So were going to have to generate one. 06:05.020 --> 06:08.540 And of course following along from the last lecture you would have actually had a curve. 06:08.580 --> 06:15.220 Im going to generate one very quickly by going to my elodie BE front door going into edit mode selecting 06:15.310 --> 06:20.900 the mesh that runs around here or rather the edge that runs all the way up and down. 06:20.970 --> 06:22.950 Thats selected it first time brilliantly. 06:23.010 --> 06:26.860 Im going to duplicate it presses scapes So its definitely not moved anywhere. 06:26.920 --> 06:34.060 Then Oulton see I of course silly me Oulton see it needs to be object mode that we do this is not going 06:34.060 --> 06:37.320 to work whilst we in edit mode of that particular object. 06:37.330 --> 06:38.550 We try it and see in there. 06:38.710 --> 06:41.540 It's an object mode operation easily done say. 06:41.560 --> 06:45.190 So we're going to convert this to a mesh from our curve. 06:45.240 --> 06:46.710 I dont need to convert the array. 06:46.770 --> 06:49.210 No we need to do the other way sorry for a curve. 06:49.440 --> 06:51.910 Our mesh and we dont need to keep the original. 06:51.990 --> 06:52.500 Okay. 06:52.770 --> 06:57.330 So now we've got all that sorted the next thing to do is go back to our door profile that we've created 06:57.330 --> 07:00.510 these bricks and fitted to the curve and bang. 07:00.690 --> 07:04.920 Hopefully it will now shoot up into the sky. 07:05.080 --> 07:07.740 Why is it not doing that so let's have a look at the door. 07:07.740 --> 07:10.460 Curve it follows round that's absolutely fine. 07:10.470 --> 07:13.830 Let's have a look at our scale factors have I scale this. 07:13.830 --> 07:16.230 No that's absolutely fine as well. 07:16.270 --> 07:17.200 Door curve. 07:17.380 --> 07:19.760 Have we go object mode in edit mode again. 07:19.920 --> 07:23.050 This is now as tall as that length is long. 07:23.100 --> 07:24.300 Okay brilliant. 07:24.300 --> 07:29.430 The next thing we need to do here is actually have it follow the curve going round. 07:29.580 --> 07:33.430 So we go to our ad modifier again and this time we're going to deform. 07:33.560 --> 07:36.780 So it's in the form it's the fourth one down with a curve. 07:36.810 --> 07:41.880 And again if we scroll down here I'm just going to minimize the array modify our curve here the object 07:41.880 --> 07:47.170 we're going to follow is the door curve and it's gone off in a random direction. 07:47.610 --> 07:50.820 So this is one of the problem solving parts of this. 07:50.820 --> 07:56.430 Now we've got to figure out why it's going off in that direction what the defamation access is probably 07:56.430 --> 07:57.110 what's going on. 07:57.110 --> 07:59.120 It goes up and over in the z axis. 07:59.190 --> 08:00.520 So we go to set up. 08:00.540 --> 08:02.590 It seems to fit but it's been offset. 08:02.670 --> 08:04.040 How annoying is that. 08:04.260 --> 08:09.640 Well it's been offset because of the difference between the objects origins. 08:09.660 --> 08:13.120 So we have a look at the door curve the origins all the way over here. 08:13.200 --> 08:16.930 We have a look at the door profile the objects origin's all the way over here. 08:17.070 --> 08:24.120 So I'm going to move my cursor my 3-d cursor first to the objects origin that we're using so the door 08:24.120 --> 08:31.450 profile in this case so shift and s cursor to selected so that's in the right place. 08:31.470 --> 08:39.300 Now we can go ahead to the door curve and in object mode go in the tool shelf itself go to set origin 08:39.510 --> 08:41.470 to the 3-d cursor. 08:41.490 --> 08:43.740 Now it should be in the right place but it's not. 08:43.740 --> 08:44.660 Why is it not. 08:44.660 --> 08:50.340 I bet it's the same issue we have before it's not in the right place at the moment because we probably 08:50.340 --> 08:52.480 need tab in and out. 08:52.830 --> 08:59.570 And in fact there we go if we hop in and out of edit mode and back into object mode it fits things imperfectly. 08:59.580 --> 09:03.720 Now I'm not sure of this smooth shading actually when it comes to this brick work so I'm going to turn 09:03.720 --> 09:04.610 smooth shedding back. 09:04.660 --> 09:06.780 Ah yes that's much better. 09:06.780 --> 09:09.240 Let's go into a rendered mode. 09:09.270 --> 09:13.770 The lighting is not too great in this scene but that is coming along really nicely. 09:13.890 --> 09:17.970 And in fact I'm just going to shove in a lamp into our scene. 09:18.000 --> 09:19.400 Let's go to a lamp. 09:19.560 --> 09:20.930 Make sure an object married yes. 09:20.940 --> 09:25.380 Sunlamp and Im going to press the ah key twice. 09:25.530 --> 09:31.140 So it's got a track ball rotation it's a lot easier to try to align things when you do that. 09:31.170 --> 09:36.810 And here we go really and that's followed around perfectly exactly how we expected. 09:36.810 --> 09:40.410 So a couple of things to remember there sometimes when you make a change youre going to have to tap 09:40.440 --> 09:48.330 in an out object mode to edit mode for Brenda for Blender to reset itself there and theres something 09:48.330 --> 09:51.260 else Ive just noticed and were going to have to rotate our curve. 09:51.270 --> 09:54.320 By the looks of it because this is not will it look like when I was creating it. 09:54.390 --> 10:00.320 So lets go back to our door curve going to go into edit mode on the tilt. 10:00.330 --> 10:01.640 I'm going to try ninety degrees. 10:01.770 --> 10:03.750 Oh that is pretty cool. 10:03.750 --> 10:05.510 It's not my intention. 10:05.760 --> 10:06.810 Yeah that is pretty cool. 10:06.810 --> 10:10.750 That's because I'm not monitoring what I'm doing if I go back into solid mode. 10:10.890 --> 10:11.250 We'll see. 10:11.250 --> 10:16.170 I've only selected this bottom vertex down here so want to set that tilt back to zero and I'm going 10:16.170 --> 10:20.320 to select everything and then I mean tilt maybe minus 90 instead. 10:20.460 --> 10:26.880 And hopefully that would have twisted everything back round how I would want it to sticks out. 10:26.880 --> 10:28.260 That way wasn't it. 10:28.290 --> 10:29.640 Oh it is minus 90. 10:29.640 --> 10:30.410 There we go. 10:30.450 --> 10:31.500 Tab in and out. 10:31.500 --> 10:32.010 Perfect. 10:32.010 --> 10:37.320 That was the intention as it goes around and that has worked really really well and it's not too bad 10:37.320 --> 10:43.080 at the top here even occasionally you have to fill about especially on this mirror point here at a mirror 10:43.080 --> 10:43.530 point. 10:43.650 --> 10:48.870 So what we could do is have it going half the length of this arch arch way itself so we can do that 10:48.870 --> 10:50.730 itself with the door curve. 10:50.880 --> 10:55.200 We come in here we select the points that we want to delete which is going to be all the way to the 10:55.200 --> 10:57.450 top one here and delete them. 10:57.450 --> 11:01.470 Now when we tab in and out it will come to this point and stop there. 11:01.590 --> 11:05.890 And then finally on the door profile we add in a mirror modify. 11:05.890 --> 11:11.310 Now this is going to be a bit different from before we can use the same mirror points that we had. 11:11.310 --> 11:13.820 We've now got this empty gap at the top. 11:14.100 --> 11:19.830 Now that's an ideal place for you guys to go in and put in a I think is called a cornerstone at the 11:19.830 --> 11:22.380 top or something like that I can't remember what it's called. 11:22.380 --> 11:26.730 There's a special name for the thing at the very top of doorways that big block you can put that in 11:26.730 --> 11:30.030 manually or Again you can tweak the curve itself. 11:30.030 --> 11:37.200 So if we go back to the curve and come into it it obviously comes up here and then doesn't go 90 degrees. 11:37.210 --> 11:43.500 So what you could do is bring that curve back ever so slightly to maybe here and then extrude a new 11:43.500 --> 11:46.500 point for it to come across like that. 11:46.500 --> 11:49.110 Now this will because I've not turned on clipping. 11:49.750 --> 11:53.300 Intersect itself and cause probably some rendering errors. 11:53.320 --> 11:57.180 So this has got to be played with and made accordingly. 11:57.310 --> 12:03.340 Now in this case I'd probably just truncate this back to around here and then add in another bit of 12:03.340 --> 12:11.140 geometry just to make up that difference there or in this case come in and solidify these these objects 12:11.170 --> 12:15.920 and adjust them after that there's lots of options that you could do with everything in blender. 12:16.060 --> 12:21.480 And of course looking at this you could come in and perhaps add a bit more of a subdivision surface 12:21.520 --> 12:22.200 modifier. 12:22.220 --> 12:25.000 The choices here are absolutely endless. 12:25.000 --> 12:30.050 Of course with me rambling on about curb's Now it's time for your challenge. 12:30.340 --> 12:32.380 Okay guys it's Challenge time. 12:32.380 --> 12:39.850 I'd like you to create curve driven mesh objects so this is incredibly powerful tool set however can 12:39.850 --> 12:44.740 be confusing and a little frustrating so we really need to nail this. 12:44.740 --> 12:46.350 What else do you think. 12:46.360 --> 12:49.030 What could you use this method for. 12:49.030 --> 12:51.590 I think I'll throw one in there straight away. 12:51.820 --> 12:54.370 A wobbly path winding through a woodland. 12:54.370 --> 12:56.670 Something along those lines a brick path of AC. 12:56.680 --> 12:58.000 Maybe even the yellow brick road. 12:58.000 --> 12:58.700 Who knows. 12:58.930 --> 13:01.530 So go ahead and add some more detail. 13:01.600 --> 13:04.370 See your other models using this technique. 13:04.440 --> 13:06.950 Pause a video now and give that a go. 13:09.110 --> 13:09.920 Okay guys. 13:09.950 --> 13:10.760 Welcome back. 13:10.940 --> 13:13.380 Let's hop back on over into a blender. 13:14.770 --> 13:15.730 Hey welcome back. 13:15.730 --> 13:19.670 So let's have a look at making this window a bit more interesting. 13:19.720 --> 13:26.790 So I'm going to borrow the curve that we've used to generate and the profile to make a. 13:29.340 --> 13:34.500 Brick that we can use in our model so let's go ahead and duplicate that curve down there and convert 13:34.500 --> 13:36.350 that straightaway to a mesh. 13:36.540 --> 13:39.600 Let's get the curve that's going on here let's duplicate. 13:39.690 --> 13:41.130 Oh that's a different curve. 13:41.130 --> 13:43.940 We don't want to keep duplicating it. 13:44.310 --> 13:45.980 That's get rid of that idea. 13:45.990 --> 13:47.530 Duplicate it in that case. 13:47.970 --> 13:49.200 Where's the. 13:49.200 --> 13:50.880 There we go the path itself. 13:50.940 --> 13:51.350 All I want. 13:51.350 --> 13:53.460 So that's duplicate that as well. 13:53.460 --> 13:55.700 And I'm going to call that a ray. 13:56.780 --> 14:01.860 I can do some renaming later and I'm going to call this a ray profile. 14:02.510 --> 14:07.430 Okay now we've got those two parts enable We just need to make sure that the array isn't causing us 14:07.460 --> 14:10.010 any problems and hide. 14:10.040 --> 14:11.160 These other two. 14:11.180 --> 14:12.870 So we know or working on. 14:12.920 --> 14:18.140 So let's go to this profile itself and hop into edit mode. 14:18.200 --> 14:25.070 Select the edge lube fill and then extrude up ever so slightly over the make these bricks quite thin 14:25.070 --> 14:27.000 so we can have a lot of them. 14:27.110 --> 14:30.460 And once I've done that we just need to set it following the path. 14:30.470 --> 14:33.810 So we're going to need an array modifier and set it. 14:33.890 --> 14:40.720 It's fit tight to fit a curve and we want it going in the z direction. 14:41.060 --> 14:46.480 And in this particular case what I can do is the Z relative offset by one. 14:46.610 --> 14:53.120 I could actually bevel the edge just here so that when they join together will not be but control and 14:53.120 --> 14:55.300 B when they actually join together. 14:55.310 --> 15:00.440 I'm not sure of a anough fine control over this at the moment and need to zoom in a bit more. 15:00.590 --> 15:04.810 But when they join together these will actually have some. 15:07.550 --> 15:10.060 Natural gaps between them. 15:10.340 --> 15:19.900 Okay so now that is done let's hop back in to the modifiers and do the curved deform using the same. 15:20.610 --> 15:21.060 Curve. 15:21.060 --> 15:26.190 Now that's not happening at the my rent and I'm guessing it's a scale problem going on again. 15:26.400 --> 15:29.670 So let's just have a look at the transformer properties. 15:29.670 --> 15:30.230 Yes. 15:30.300 --> 15:32.540 So let's apply for scale. 15:33.970 --> 15:35.140 And would backup here. 15:35.140 --> 15:40.660 Something still isn't working properly that's Have a look at the array and turn the curve off list do 15:40.660 --> 15:42.300 one thing at a time. 15:42.310 --> 15:43.240 There should be lots of those. 15:43.240 --> 15:48.100 I haven't assigned the array itself the curve objectively array. 15:48.100 --> 15:56.020 Now let's go back on to deform and see whether or not we need to generate R own curve. 15:56.050 --> 15:57.580 Yes we do. 15:57.610 --> 16:01.710 So let's go ahead and create a Bezier curve that will follow this path. 16:03.920 --> 16:07.940 Fortunately I already have the origin in the right place. 16:07.940 --> 16:13.920 So here I can move the cursor to the selected because that'll move it over there. 16:13.940 --> 16:20.360 We can add ourselves a Bezier curve and start moving control points about and was done doing that. 16:20.360 --> 16:22.030 I will fast forward the video. 16:27.970 --> 16:31.920 I'm going to remember here to set my resolution down at 1. 16:32.160 --> 16:39.640 And now that the curve is complete I should be able to go back to my array profile and change the properties 16:39.640 --> 16:43.280 here in the modifiers to follow the new Bezier curve. 16:43.490 --> 16:45.380 Okay so looking a bit. 16:45.430 --> 16:47.920 It's looking kind of right but kind of funny as well. 16:47.950 --> 16:51.940 I think what's going on here is something gone wrong with the curve itself. 16:51.940 --> 16:55.040 Let's have a look at that Bezier curve in more detail. 16:55.060 --> 16:58.110 I think it's probably these control points. 16:58.120 --> 16:59.000 Yes it is. 16:59.850 --> 17:06.310 Some just going to turn off a self snapping and snap it to the same point there. 17:06.330 --> 17:10.390 That should bring it back round to looking pretty decent. 17:10.770 --> 17:12.430 Yeah that's looking pretty sweet. 17:12.430 --> 17:13.860 Now that's really good. 17:13.860 --> 17:15.610 I like the way that that's come out. 17:15.630 --> 17:19.130 I think it's probably a little thick but we can always obviously modify our. 17:19.290 --> 17:25.070 Okay there's there's a bit of rotation going on here I can see that's not the profile I'm looking for. 17:25.500 --> 17:28.750 So let's highlight everything and mean tilt. 17:28.770 --> 17:36.010 Last time it was up to 70 or hundred or minus 90 and that looks spot on. 17:36.150 --> 17:40.980 There's a couple of other things I'd want to hear there's some odd stuff going on is that a rendering 17:40.980 --> 17:43.100 artefact or something else going on. 17:43.170 --> 17:45.710 I might have crossed something over at some point. 17:45.720 --> 17:47.090 Wrong. 17:47.250 --> 17:50.540 It being a rendering artefact wouldn't necessarily be a bad thing laughing. 17:50.550 --> 17:55.120 Looks pretty cool but I can investigate later as to what's going on there. 17:55.140 --> 17:58.890 How are your archways and how's the rest of your building coming on. 17:58.890 --> 18:00.530 I'd love to see your results. 18:00.570 --> 18:05.690 Please remember to share in the discussions and I will see you guys in the next lecture.
