WEBVTT 00:00.330 --> 00:04.130 In this lesson, we're going to clean up the head, the first one you take a look at the neck. 00:04.230 --> 00:10.530 If we click on the neck control and we rotate it around, we can quickly see that it doesn't follow 00:10.530 --> 00:13.550 the neck joint exactly one hundred percent. 00:14.010 --> 00:21.560 So this is a case where we need to go in and adjust the skin weights on this part of the geometry so 00:21.560 --> 00:24.000 that the geometry selected will go into skin. 00:25.110 --> 00:32.850 Paint, skin, whites, and we need to open up the tool settings here so we can see the bones neck and 00:32.850 --> 00:36.690 we can pretty easily see that this is pretty great out and it's not 100 percent. 00:36.690 --> 00:42.350 So we want to attribute this on 100 percent to the neck joint. 00:42.510 --> 00:45.480 So a quick way that we can do that, we could paint that. 00:45.480 --> 00:46.590 But let me show you one other way. 00:46.590 --> 00:50.850 Now that we have a little more knowledge of how things work. 00:50.880 --> 00:52.470 Let me show you one new way. 00:52.840 --> 00:57.210 I'm going to go to the vertices option here by right clicking and dragging order vertex. 00:57.810 --> 01:01.890 And I'm going to select everything that I want to follow the neck joint. 01:02.400 --> 01:05.460 I want to undo that because it's trying to select the next joint. 01:05.460 --> 01:08.460 So I'm going to click this little button that says Don't select joints. 01:09.240 --> 01:11.160 And I'm going to try that selection one more time. 01:13.050 --> 01:17.400 And now I'm going to go into the Windows component. 01:17.400 --> 01:17.910 Ed. 01:21.540 --> 01:31.440 And if we drag this out, we can see smooth skins over here and what this is, is a table telling you 01:31.440 --> 01:36.450 exactly the influence of each joint on each of these vertex. 01:36.460 --> 01:43.590 We can see a vertex with a number and it's basically saying it's 50/50 for most of these. 01:43.600 --> 01:45.200 We can scroll through and see all of them. 01:45.210 --> 01:51.060 But what we can do that is much quicker than painting because we know we want them to be 100 percent 01:51.060 --> 01:56.220 is just click the top one and then shift, click the bottom one and now type of one. 01:57.120 --> 02:02.880 And very quickly now, if we go back into the paint can weights tool here go to object mode. 02:02.880 --> 02:03.090 Right. 02:03.090 --> 02:04.680 Clicking going to object mode. 02:05.520 --> 02:10.440 If we go to the paint skin weights I can get two from the most recent used tool here. 02:10.440 --> 02:16.200 You can see now everything that I had selected is totally white because it's one hundred percent. 02:16.710 --> 02:25.770 So let me go into the tool real quick and I'm just going to smooth out this neck joint so you can watch 02:25.770 --> 02:31.770 this get smooth here over this one joint when a flood that and now we smooth that out. 02:31.800 --> 02:38.370 So let's go back to the con, the controller of the neck joint and see that it is one hundred percent 02:38.370 --> 02:41.250 controlled by that joint. 02:41.430 --> 02:41.820 Right. 02:42.690 --> 02:44.130 That's pretty close to what we want. 02:44.160 --> 02:45.420 We can adjust this more. 02:45.420 --> 02:48.720 We could, you know, have that be a smoother transition. 02:48.720 --> 02:50.190 So it's not over one joint. 02:50.640 --> 02:56.820 But you get the idea this is a pretty cool way to go through that spreadsheet instead of visually having 02:56.820 --> 03:01.890 to paint things and not entirely know if it's 100 hundred percent on that one joint, we can just tell 03:01.890 --> 03:07.950 it, hey, you're one hundred percent you're one point zero are going to follow that joint. 03:08.520 --> 03:10.020 So now we have that resolved. 03:10.020 --> 03:18.390 Let's let's actually now constrain the geometry to this head control, because we the way we rigged 03:18.390 --> 03:23.460 it up, we know the head control already works, just the head geometry isn't hooked up to it yet. 03:24.150 --> 03:32.520 So let's find the geometry in the outliner by F and we can see there's also that plane back here. 03:33.390 --> 03:35.190 But let's make a group just for the head. 03:35.190 --> 03:38.910 So I'm going to hit Command G and call this the head group 03:41.790 --> 03:45.270 and I'm going to constrain the group to the head control. 03:45.270 --> 03:50.940 So select the head control first and then the head group and then go to constrain parent constraint. 03:51.630 --> 03:57.870 So now we can see that the head is indeed constrained to that control. 03:58.560 --> 04:00.510 So kind of magical. 04:00.510 --> 04:07.560 Part of what we're going to learn in this video is about Blende shapes and what Blende shapes. 04:07.560 --> 04:13.410 Our Blende shapes are basically a way to deform geometry based on a sculpt. 04:13.530 --> 04:17.490 It's kind of like post-paid defamations, but it's a little different. 04:17.500 --> 04:22.860 Post-paid defamations came after BLENDE shapes, PLEN shapes historically came first and then they developed 04:23.280 --> 04:26.280 post-paid defamations actually fairly recently. 04:27.030 --> 04:28.920 But Blunt Shapes is kind of the original. 04:28.920 --> 04:29.580 The former. 04:29.910 --> 04:30.390 Right. 04:30.390 --> 04:31.770 And it's very useful still. 04:32.700 --> 04:37.410 So let's duplicate out the head and we'll drag it over here. 04:37.890 --> 04:41.700 And I'm just going to delete the eye mask here because we don't need that. 04:41.700 --> 04:42.960 We just want the head geometry. 04:43.650 --> 04:50.070 And I'm going to drag this over and I'm going to shift to select the original head. 04:50.080 --> 04:54.510 I'm going to go to deform and go down to blend shape. 04:54.510 --> 04:57.420 It's the first one open up the option box. 04:57.420 --> 05:02.490 And let's name this buffer BBs for Blende Shape. 05:02.700 --> 05:03.210 All right. 05:03.900 --> 05:06.600 And all of that's fine. 05:06.600 --> 05:15.780 And will it create so what this is is basically going to be the intermediary between the original head 05:16.110 --> 05:19.560 and all of the BLENDE shapes that we're going to make over here? 05:19.680 --> 05:24.600 OK, they're going to filter through this one thing so we can turn this on. 05:24.600 --> 05:30.240 We can see now we have an input of buffer B.S. over here on the inputs so we can click that and we can 05:30.240 --> 05:31.920 see has had one. 05:31.920 --> 05:33.330 And that's named for the geometry. 05:33.330 --> 05:34.290 This is head one. 05:34.950 --> 05:43.020 And we can turn that from a zero to a one, some middle mouse drag in the viewport and turn that up 05:43.020 --> 05:43.470 the one. 05:44.250 --> 05:48.900 So watch what happens just real quick so you can kind of get an idea of what this is going to. 05:48.900 --> 05:52.440 It's like some vertices in it, B and I'm going to yank them around. 05:53.250 --> 05:57.690 And now you can see that it affects the geometry. 05:58.290 --> 05:59.730 So why is this important? 05:59.730 --> 06:02.510 Because it looks like it's doing why don't we just do this directly to the thing? 06:02.520 --> 06:05.070 Well, the difference is we could do this. 06:05.610 --> 06:10.080 And then on the balance sheet buffer B.S. here, we could just turn it off. 06:10.860 --> 06:19.140 So what we're going to do is apply those types of defamations to the buffer head and they're going to 06:19.140 --> 06:20.910 all filter down instead of having to. 06:20.980 --> 06:25.720 Turn on, you know, 20 different things, we're going to have one controller through the buffer head 06:25.720 --> 06:28.110 so we can turn them all on or off if we want to. 06:28.810 --> 06:32.640 And it's just a nice kind of way to organize blend shapes. 06:32.920 --> 06:39.460 So I'm going to duplicate this head out again and I'm going to move this over a little bit so we can 06:39.460 --> 06:39.760 tell it. 06:39.880 --> 06:43.090 It's not the buffer blend shape, actually. 06:43.090 --> 06:44.830 Duplicate this out a few times. 06:45.760 --> 06:53.330 And I'm basically going to model on these different types of poses that I want. 06:53.860 --> 06:58.810 So in the most obvious case, I think would be to create a blink. 06:59.200 --> 07:03.730 So I'm going to go to edge mode and I'm going to double click on an edge here. 07:03.730 --> 07:10.900 I'm going to be to turn off self select and I'm going to select the kind of middle and the inner one 07:11.530 --> 07:13.900 that's going to do that on both sides. 07:14.950 --> 07:20.560 And I'm going to be to turn on self select and just kind of scroll that out a little bit. 07:21.400 --> 07:27.580 And I'm just going to try to make a blink real quick so I can just scale that down. 07:27.700 --> 07:35.380 And I actually turn on down here, holding down our left, clicking, I can say prevent negative scale 07:36.190 --> 07:39.610 so I can just bring that down and not have to worry about it going through itself. 07:40.690 --> 07:42.520 So it will stretch the textures. 07:42.520 --> 07:44.500 That's something you need to be aware of. 07:44.800 --> 07:46.810 So the textures are obviously going to stretch. 07:46.810 --> 07:51.540 But, you know, that's that's a price you have to pay for this defamation. 07:51.940 --> 07:54.790 So now what we can do, we can have the blink. 07:55.210 --> 08:00.730 Let's have maybe let's even have it be a wider eye. 08:01.210 --> 08:03.190 So let's make that same selection. 08:06.370 --> 08:08.680 And expand the. 08:10.070 --> 08:11.500 So we can scale this up. 08:13.340 --> 08:20.990 And might even just go straight up and down and maybe increase the soft selection area here, go straight 08:20.990 --> 08:21.680 up and down. 08:26.970 --> 08:35.460 And I'm going to maybe dislike some of this so we can scale in towards the bridge of the nose a little 08:35.460 --> 08:35.820 bit. 08:40.220 --> 08:48.080 So now we have wide eyed, we have a blank, we can make new brow shape, we can do a lot of different 08:48.080 --> 08:48.870 things. 08:49.910 --> 08:55.870 Let me just choose these two and I'll drag them up. 09:00.940 --> 09:07.090 We'll be limited by kind of a texture a little bit here to change the brow shapes. 09:07.740 --> 09:15.280 It'll be a little more challenging because we're kind of fighting against the shape of the texture that 09:15.280 --> 09:15.930 we drew. 09:16.570 --> 09:21.970 But it's still definitely possible to affect this stuff. 09:27.810 --> 09:31.170 And just kind of taking a look in all directions here to make sure. 09:32.650 --> 09:35.650 It's kind of staying true to form a little bit. 09:38.070 --> 09:45.090 So basically, what we can do is when we have a point that we like, let me just I'm going to duplicate 09:45.090 --> 09:46.740 one more and have an angry face. 10:11.060 --> 10:17.750 So now we have four different models that we can select all of them at once and now apply as a blend 10:17.750 --> 10:19.440 shape to the buffer head. 10:19.940 --> 10:26.660 So let's go back up to deform blend shape and we'll call this expression's. 10:27.860 --> 10:31.190 And before we do that, actually, let's call this blank. 10:36.630 --> 10:37.680 Why'd I? 10:43.330 --> 10:44.440 High brow. 10:47.580 --> 11:01.890 And angry, and I'm going to do one more just for fun, and I'm going to call that extra. 11:03.680 --> 11:10.550 And I want to select all of these and shifts like the head and call these expressions and head apply. 11:11.620 --> 11:15.250 So now what's happened is on the buffer blend shape. 11:15.670 --> 11:25.770 We have this input called expressions, and we have each model represented in an animated BL layer here. 11:26.260 --> 11:34.720 So now we can get the head to actually animate and we could use multiple ones of these together. 11:36.280 --> 11:43.600 So it's pretty cool and we're going to learn a little bit more about how to animate these and in the 11:43.600 --> 11:49.170 animation part, but it's fun to just play around with this stuff and you could separate this out. 11:49.180 --> 11:53.920 You could have, you know, do one blink for the left eye and blink for the right eye and separate. 11:53.920 --> 11:55.810 You could go really deep on this stuff. 11:55.840 --> 11:57.300 You could have a ton of blinn shapes. 11:57.640 --> 12:05.560 And this is how and big feature films, how they create different facial, different facial expressions. 12:05.980 --> 12:12.250 And they can have, you know, 100 of these things are more even to capture what a human face would 12:12.250 --> 12:12.550 do. 12:13.150 --> 12:15.130 So play around with that. 12:15.490 --> 12:20.140 And then I'm going to I think at this stage of the game, if you've made it this far in the course, 12:20.590 --> 12:30.190 I think you can go back and create your own attribute, go to add attribute and then create a set driven 12:30.190 --> 12:33.040 key of the expressions. 12:33.040 --> 12:33.520 Right. 12:33.520 --> 12:34.600 Set driven key. 12:35.230 --> 12:44.020 And I'm going to leave that up to you as homework to make a set driven key on add new attributes to 12:44.020 --> 12:44.770 the head control. 12:45.070 --> 12:45.580 All right. 12:46.120 --> 12:47.620 That is going to be the homework for this. 12:47.620 --> 12:49.060 I feel like you've made it this far. 12:49.070 --> 12:50.080 You should be able to do that. 12:50.500 --> 12:57.310 And if you can't, then you need to go back and watch the set driven key lesson and then you'll be able 12:57.310 --> 12:57.910 to do that. 12:57.920 --> 13:02.680 So just to to make this in your mind, I want you to have to do that yourself. 13:02.680 --> 13:11.620 Otherwise, I don't think you'll learn as much so we can hide all of this stuff and we can always come 13:11.620 --> 13:14.150 back to it and change these models as well. 13:14.230 --> 13:20.500 OK, but they're all in this head group, so we can just group them together and call these B.S. for 13:20.500 --> 13:23.830 blend shape and just hit hide. 13:24.670 --> 13:28.390 So go through and make those set driven keys. 13:28.810 --> 13:31.780 And in the next lesson, we're just going to clean up this rig. 13:31.780 --> 13:36.960 So it's going to be ready for animation and then we'll be done with this part of the longer course here. 13:37.360 --> 13:38.110 Thanks for watching.
