WEBVTT 00:00.180 --> 00:02.400 Welcome to basic sculpting. 00:02.400 --> 00:05.680 In this video you will learn the basics of sculpting. 00:05.820 --> 00:09.300 Adjust your brushes type strength and size. 00:09.510 --> 00:14.720 Understand how dynamic top policy works and when to use it. 00:15.030 --> 00:16.710 And then finally how to find a brush. 00:16.710 --> 00:21.590 If you've accidentally deleted it send it on straight on over in a blender. 00:22.940 --> 00:23.840 Right so. 00:23.900 --> 00:27.650 Well now we're over in blender The first thing I want to do is we're going to be playing with something 00:27.650 --> 00:29.070 that's quite destructive. 00:29.120 --> 00:33.130 So I don't want to work on our fluffy bunny for the moment. 00:33.220 --> 00:39.270 Somebody go ahead and open up a brand new blender file with our default cube in it and I suggest you 00:39.270 --> 00:39.800 do the same. 00:39.800 --> 00:42.130 Now to play with the sculpting tools. 00:43.120 --> 00:48.160 So let's go ahead and start playing with the sculpting tool so if we hop down to where it says object 00:48.160 --> 00:55.240 mode we've got a series of options and we're going to click on scolloped mode and you will see on the 00:55.270 --> 00:59.260 left hand side in the tool shelf the menu options change. 00:59.250 --> 01:02.030 Down here there are different tabs going down. 01:02.090 --> 01:05.590 We're going to be focussed on each just the tools one here and I'm going to pull this out so we can 01:05.590 --> 01:09.380 see a bit more of what's going on and down at the bottom here. 01:09.400 --> 01:12.960 The menus have changed ever so slightly. 01:13.030 --> 01:15.250 So what does this do. 01:15.250 --> 01:22.570 Well we can literally start changing our cube about now as you can see um left clicking here and it's 01:22.570 --> 01:26.260 kind of pulling the corners of ask you about we're not really changing its shape. 01:26.260 --> 01:28.440 There's nothing awesome going on yet. 01:28.450 --> 01:33.910 Now the reason for that is the brush tool directly affects the underlying mesh. 01:33.910 --> 01:38.830 So in this case there are only eight vertices so the only thing I can move are the eight vertices and 01:38.830 --> 01:41.060 everything else is joined to that. 01:41.080 --> 01:48.700 So if I were to add more vertices to this mesh so if we go in and quick we're doing this is probably 01:48.700 --> 01:54.110 just subdividing it and applying the subdivision so I'm going to go over to our modifiers. 01:54.130 --> 01:58.910 I'm going to go down on the generate column turn subdivision surface modifier. 01:58.960 --> 02:01.640 Of course it makes it kind of spherical. 02:01.780 --> 02:05.880 I'm just going to add two subdivisions and apply them. 02:05.950 --> 02:11.050 So now we have some more geometry to play with and we can see that in wireframe mode as well. 02:11.050 --> 02:16.730 We've now more FA model about now it's not moving very much at the moment as we try and move it I'm 02:16.780 --> 02:20.670 just clicking away and wiggling around and there we go. 02:20.670 --> 02:25.930 It starts to move up and every time you go over the top of one of those verses again it moves it out 02:25.930 --> 02:31.960 slightly and we can see here this is the type of brush we have and we're currently adding you can subtract 02:31.960 --> 02:36.830 of course which does the reverse and pushes stuff in there we go. 02:36.970 --> 02:38.960 So let's flick that ad for the moment. 02:39.070 --> 02:42.890 Now the first thing I'm going to deal with is this radius and strength. 02:43.000 --> 02:45.130 So the radius is the size of that brush. 02:45.130 --> 02:51.280 Now you notice it's in pixels Now this is important because if you zoom in or out on your model you 02:51.280 --> 02:56.660 see when it's all the way zoomed out here were affecting the entire model by doing this sculpting. 02:56.710 --> 03:03.340 If we were to zoom in and we're only affecting one vertex in fact in this case but the radius of the 03:03.340 --> 03:04.940 brush hasn't changed. 03:04.940 --> 03:09.340 So depending on the scale of your model your radius will differ. 03:09.340 --> 03:14.210 Now the shortcut for adjusting the radius of your brush is the F key on the keyboard. 03:14.380 --> 03:21.490 And if we press F now we can see we can make that brush bigger and smaller and that outer red circle 03:21.490 --> 03:24.180 will show the new sides. 03:24.190 --> 03:31.910 Now you'll notice that it's faded and it's faded because it doesn't affect the entire area. 03:32.110 --> 03:37.750 Equally it affects the middle more so than the edges and that helps with your sculpting otherwise you'd 03:37.750 --> 03:39.730 end up with a very sharp lines. 03:39.730 --> 03:45.040 Now if that's something that you wanted then you can control that the strength itself is currently set 03:45.040 --> 03:50.380 to 50 percent and the strength allows you to be much more gentle with your sculpting. 03:50.410 --> 03:53.780 So imagine that this was a real piece of clay in front of us. 03:53.860 --> 03:59.350 If you went for it really heavily with a tool you would end up making more of an impression of changing 03:59.350 --> 04:01.610 it more than if you were very gentle. 04:01.810 --> 04:08.050 Ultimately you can do the same amount of sculpting at 50 percent you just have to do something twice 04:08.050 --> 04:12.240 to get the same result as if it was up at 1 or roughly speaking. 04:12.250 --> 04:17.200 However the lower the strings it does afford you more control when you're working on something detailed 04:17.610 --> 04:18.290 now. 04:18.430 --> 04:21.440 Unrest set the size of our brush down a little some. 04:21.490 --> 04:23.970 To press the F key and move it back down. 04:24.460 --> 04:31.480 So the strength of the brush can be changed either here in the tool shelf or it can be changed with 04:31.480 --> 04:34.540 the sheath and F key. 04:34.540 --> 04:37.900 Now you notice it gets this way is a bit counterintuitive. 04:37.990 --> 04:44.590 The brush gets weaker or weaker less strength when you go towards the outer edge of the circle. 04:44.590 --> 04:51.020 The big circle here and stronger as you move in and in so you'll want to pick. 04:51.040 --> 04:52.930 I usually leave it around 50. 04:52.930 --> 04:57.490 But if you need to make massive changes quickly obviously you can bump the strength up and if you need 04:57.490 --> 05:03.550 to be more gentle and subtle with your changes you can lower the strength and have more control. 05:03.550 --> 05:05.620 Now we've already covered the add and subtract. 05:05.620 --> 05:10.720 They basically mean are you pulling the model outwards or pushing it inwards but at the top. 05:10.720 --> 05:13.710 We've got this picture so we're not quite doing this in order here. 05:13.840 --> 05:19.810 But that at the top we've got a picture of a brush and if we click on that it gives us a selection and 05:19.810 --> 05:22.210 these are the default selection. 05:22.240 --> 05:29.650 So we've got one two three four 8 16 18 different brush types to choose from and they all affect our 05:29.650 --> 05:32.050 models slightly differently. 05:32.080 --> 05:36.440 Obviously you can customize these like you can anything in blender. 05:36.460 --> 05:39.920 That also means you can unfortunately delete something. 05:39.940 --> 05:42.290 So if I go ahead now and. 05:42.380 --> 05:45.090 Let's say this blob won't select it. 05:45.200 --> 05:51.590 Now during the messing about up here if you were to experiment with it if you accidentally hit the F 05:51.590 --> 05:58.940 key which removes the users from it and creates a fake user and then click the cross for some bizarre 05:58.940 --> 05:59.940 reason. 06:00.110 --> 06:02.650 And on top of that so it's still there at the moment. 06:02.650 --> 06:05.310 You can see it's just there but it's got a zero next to it. 06:05.510 --> 06:09.040 But if I now save this blend file. 06:09.280 --> 06:12.210 So let's go ahead and save it and brush gone test. 06:12.920 --> 06:17.380 Now if I call quits from my blender program. 06:18.630 --> 06:22.250 Okay now I have quitted from Blender start it back up again. 06:23.270 --> 06:25.410 Need it bring it down on to this screen. 06:25.700 --> 06:27.050 Make it the right size. 06:27.210 --> 06:32.170 Okay so go file an open response and go to brush contest. 06:32.210 --> 06:33.810 Now it's not there anymore. 06:33.980 --> 06:39.500 So if you hadn't realized you had done this you need to get that brush back so let's cast our eyes to 06:39.500 --> 06:41.640 the sculpting head down at the bottom. 06:41.810 --> 06:44.480 And there's a word there that says brush. 06:44.590 --> 06:50.410 Okay and then if we click on that there are a series of options here one of which is sculped tool. 06:50.420 --> 06:52.790 And the one that we've deleted was called blob. 06:53.090 --> 06:59.030 So you may have to refer to an unaltered blender file if you were to do that but here we can go ahead 06:59.060 --> 07:03.670 and go blob and that's added it back to our. 07:05.380 --> 07:06.450 Oh no sorry. 07:06.460 --> 07:13.210 That's overwritten the one that was there previous which was brush sculpt Clay case and we need to click 07:13.210 --> 07:17.240 the plus to lock clays 001 and you can see that's here. 07:17.350 --> 07:21.160 And with that one selected we can go in and go brush. 07:22.010 --> 07:24.210 Sculpt tool blob. 07:24.350 --> 07:27.570 And of course rename it's here to blob. 07:27.830 --> 07:34.160 So if you wanted to modify your tools and you actually found a brush type you light and you were working 07:34.160 --> 07:37.920 with volts you could go ahead and create a custom type. 07:38.030 --> 07:41.080 And now you can see there are FS all across these. 07:41.090 --> 07:46.340 That means it's got a fake user so that when you close blender down and open it back up again you will 07:46.340 --> 07:47.660 see this again with materials. 07:47.660 --> 07:52.180 In fact we covered it briefly in the material section before it has a zero next to it. 07:52.190 --> 07:57.570 It means that the next time you close blender and reopen it it won't exist anymore. 07:58.070 --> 08:02.270 Okay so finally we scroll down here you might not have the score yourself. 08:02.270 --> 08:06.490 There's something here that says Dean toppo or dynamic topology. 08:06.530 --> 08:11.210 Now as we mentioned to begin with this is actually turned off. 08:11.600 --> 08:20.320 Now when I move this is moving that single vertex about if I enable dynamic topology it gives us. 08:20.510 --> 08:25.680 You can see straightaway it's triangulated our mesh it needs to do that it can't work with quads. 08:25.880 --> 08:34.880 And if we go in here and start modelling you see that is adding new vertices to our model enabling us 08:34.880 --> 08:38.090 to add a fine amount of detail to that small area. 08:38.390 --> 08:45.670 Yet if we look at the underlying mesh all in fact it's got reflection turned on as well that's important 08:45.670 --> 08:47.200 and have a look at that in a moment. 08:47.420 --> 08:54.660 So this here is adding detail where we need detail but keeping the rest of our model plane. 08:54.800 --> 09:00.670 Now that is quite important when you're modelling because in this area here doesn't need lots of geometry. 09:00.710 --> 09:06.060 It's pointless having lots of geometry and if you cast your eyes up to the top we can see this. 09:06.230 --> 09:11.990 This model now has nearly twelve hundred verses and if I draw some more in there it will go down. 09:11.990 --> 09:13.290 Now why is it gone down. 09:13.340 --> 09:15.700 Because I was zoomed out slightly. 09:15.710 --> 09:20.610 In fact if I zoom out a lot so this brush size is the entire model and click. 09:20.610 --> 09:25.700 It's dropped everything down so you can see that dynamics apology is very useful. 09:25.910 --> 09:32.990 But if you didn't know that actually zooming out and using it will actually lower the amount of polygon 09:33.110 --> 09:37.910 in your scene that could be very destructive if you've just been working on some detail. 09:37.910 --> 09:40.390 You'd have to obviously go and undo it. 09:40.510 --> 09:44.730 But if you'd gone past your undo buffer you'd be pretty much stuck. 09:45.170 --> 09:47.940 Okay so final thing now on reflection. 09:48.020 --> 09:50.440 So further down we've got symmetry. 09:51.380 --> 09:58.020 And we can see here the direction on dynamic top ology here because we've got it enabled it is minus 09:58.020 --> 10:05.680 X 2 plus X so if we were looking front onto our model here and this was the site we can give it some 10:05.940 --> 10:11.380 must give it some is I suppose if you wanted or a nose and we can see that we can start building out 10:11.380 --> 10:19.300 a model very quickly and I haven't really played with this too much going on here and we can see if 10:19.300 --> 10:21.810 we turn dynamic top ology off. 10:22.700 --> 10:29.180 Symmetry and symmetry lock down here is locked to the x axis at the moment which means that as you can 10:29.180 --> 10:35.630 see here along the access it will mirror and we can change that if we want to the y axis which will 10:35.630 --> 10:39.630 do this way and then Z access wince will do the top and the bottom. 10:39.660 --> 10:43.800 And of course that will depend on the orientation of your model. 10:44.240 --> 10:48.970 So one final thing to cover here is smoothing the auto smooth feature. 10:49.100 --> 10:54.890 So as you're going around your model and adding You may end up with it not being quite as smooth as 10:54.890 --> 10:55.820 you wanted. 10:55.820 --> 11:01.580 Now there is a brush here that is smoothing as well which is this one here looks granya and smooth and 11:01.580 --> 11:04.210 that one itself will help smooth out details. 11:04.220 --> 11:08.570 If you've made too much of a sudden change in your model. 11:08.660 --> 11:15.310 Now if we have a look back at a normal brush time let's go back to blob and we can see here also smooth. 11:15.320 --> 11:21.430 If we turn that up as you're modelling it will help smooth out the details so it won't be as aggressive. 11:21.650 --> 11:28.640 The other thing that you can do when your modelling is press the shift key and this will smooth as your 11:28.640 --> 11:33.170 modelling so it's no longer doing the blob it's doing smoothing so it can help flatten out details. 11:33.200 --> 11:40.090 If I let's go here it's up the strength to one and really bring this out here. 11:41.890 --> 11:47.380 Let's turn on dynamic topology as well to make sure we get detail in there as well so that's bringing 11:47.380 --> 11:49.890 it really far forward like that. 11:49.900 --> 11:56.020 Now if we wanted to make all this jaggedness smooth Well we can just hold down Shift as I'm just going 11:56.020 --> 11:58.750 to make the window a bit bigger so we can see what's going on. 11:58.750 --> 12:05.230 I can hold down Shift as I'm doing this just to run over these aggressive details to smooth them out. 12:05.230 --> 12:12.310 Now of course if you wanted a large amount of detail then you may want to go back again with a smaller 12:12.310 --> 12:14.390 brush and add in that detail. 12:14.620 --> 12:19.240 Now do be careful when using the smooth of course because as you can see here this lovely point that's 12:19.240 --> 12:20.080 coming out. 12:20.080 --> 12:24.880 If I just smooth it eventually it will end up flattening it back down because that's what it will tend 12:24.880 --> 12:25.660 towards. 12:25.750 --> 12:28.530 But smoothing your model out helps massively. 12:28.900 --> 12:31.350 And we can see here that you can see all the faces. 12:31.360 --> 12:34.810 Perhaps you don't like that of course in object mode. 12:34.810 --> 12:39.120 What we haven't done here is set the shading to move it we set the shading to move. 12:39.250 --> 12:43.270 We get a much better appreciation of how that's looking. 12:43.270 --> 12:48.100 Of course when it's flat we get a much better pression of the underlying geometry. 12:49.070 --> 12:51.050 Okay guys it's Challenge time. 12:51.050 --> 12:53.830 I'd like you to define your bunny shape. 12:54.050 --> 13:00.050 So the head will want the most detail since it's a focal point for our model recommends making sure 13:00.050 --> 13:04.120 symmetries turned on it's going to make making your model much much better. 13:04.130 --> 13:10.370 Now use reference material for an accurate shape although if you do want to caricature your bunny rabbit 13:10.400 --> 13:11.820 then please do so. 13:11.820 --> 13:12.320 It's cheap. 13:12.340 --> 13:13.550 Remember this is your model. 13:13.550 --> 13:15.560 There's no right way of modelling a bunny. 13:15.560 --> 13:18.940 As long as everybody sees it as a bunny that is great. 13:18.980 --> 13:27.530 Now do models the is at this stage to using whatever method you want an ad to use is for the eyes and 13:27.530 --> 13:30.290 keep them as a separate object for now. 13:30.290 --> 13:37.360 Now I would suggest with the IS themselves that too quickly block model a couple of years basically. 13:37.400 --> 13:44.150 And then join them to the rest of the mesh rather than trying to use the sculpting tools to create is. 13:44.150 --> 13:47.480 Although if you want to do that do give it to go have fun with it. 13:47.560 --> 13:49.970 Pause a video now give that a go. 13:50.000 --> 13:56.570 Now because of the length of the solution for this video the actual solutions will not be in this lecture. 13:56.570 --> 13:58.940 It will be in the following lecture. 13:59.210 --> 14:04.340 So get creating your bunny and I will see you in the next lecture.
