WEBVTT 00:00.240 --> 00:03.210 In this lesson, we're going to learn about post-paid defamations. 00:03.510 --> 00:10.410 But first, I just want to show you a more typical example of using skin paint weights to affect the 00:10.410 --> 00:10.830 model. 00:11.160 --> 00:13.890 So I'm going to select the joints as we know. 00:13.890 --> 00:20.460 We need to do our custom menu and select the hierarchy of it and then select the geometry and go to 00:20.460 --> 00:24.030 skin, bind skin and just use the default that we had before. 00:24.360 --> 00:25.610 And I'll think for a second. 00:25.620 --> 00:30.510 And now we can take a look at the weights that we get just out of the box. 00:30.510 --> 00:37.070 And for this example, I'm just going to be manipulating the joints themselves instead of the cons. 00:37.080 --> 00:40.250 Or we would do if we were properly rigging this buffer speed. 00:40.260 --> 00:47.780 I'm just going to use the joints so we can see that it's pretty messed up and unusable. 00:48.150 --> 00:51.260 So let's take a look at a pose. 00:51.270 --> 00:57.930 Let me just I'll hit on my keyboard to set a key to make sure that we save the default pose because 00:58.170 --> 00:59.280 we're using the joints. 00:59.280 --> 01:06.900 We don't actually have a zeroed out con that we can use and know that if we go to zero, that it'll 01:06.900 --> 01:08.280 go back to the default pose. 01:08.310 --> 01:14.190 If I were to start manipulating this and then try to get back to default, I wouldn't really know where 01:14.190 --> 01:16.350 that would be because it's not zeroed out. 01:16.800 --> 01:21.180 So that's just gives you an example of why zero out your controllers are important if you ever want 01:21.180 --> 01:22.490 to get back to the default pose. 01:23.030 --> 01:28.230 So let me just scrub for it here and then I will crank this shoulder up. 01:28.590 --> 01:34.410 And you can see, because I have the auto on over here, that it automatically set a key for me because 01:34.410 --> 01:39.150 it was keyed once than any time it's moved on another frame, it'll automatically quit. 01:39.750 --> 01:41.300 So we basically have this range. 01:41.310 --> 01:45.630 I'm just going to drop the timeline down so we can scrub the whole timeline here. 01:46.470 --> 01:48.300 We basically have this range now. 01:48.300 --> 01:54.300 We can work on the skin painting the skin Waite's so with the geometry selected I'm going to go to skin 01:54.600 --> 01:57.210 and go down to the paint. 01:57.210 --> 02:02.070 Skin waits and nothing happens and we have the axe on the brush because we need to go to the tool settings 02:02.070 --> 02:02.910 first to get them. 02:03.300 --> 02:09.990 So now we get back to this familiar scene where we have the black and white and we need to see the shoulder. 02:09.990 --> 02:14.790 So let's scrub down into the name joints and go to the left shoulder. 02:15.450 --> 02:22.060 Now, instead of going back and forth between the rig and the paint, skin waits till now. 02:22.060 --> 02:25.830 All we have to do is just scrub the timeline and we get this range of motion. 02:26.130 --> 02:34.230 If we didn't do this, then it would be a major pain to have to constantly switch between these manipulators, 02:34.230 --> 02:35.940 putting it in position that we want it. 02:36.090 --> 02:42.060 Then go back to the paint skin waits tool, then select the joint, then go to work on it and it would 02:42.060 --> 02:43.260 be a major pain. 02:43.470 --> 02:46.830 So this is a much easier way to deal with that. 02:47.190 --> 02:50.370 Let me just delete that key frame because we don't want that. 02:50.370 --> 02:52.230 I'm just clicking on it and going to delete. 02:52.980 --> 02:57.120 So I'm going to select the paint skin whites tool and the geometry. 02:58.260 --> 03:04.110 I need to have the geometry selected for that to kind of register and I'm going to get back to the shoulder. 03:04.110 --> 03:09.260 So now you can see why it's important to set those couple of keys, those two key frames. 03:09.260 --> 03:18.090 So now we can just stay here and go to different ranges of motion and effect the rig and the skin painted 03:18.090 --> 03:18.750 skin weights. 03:19.230 --> 03:26.100 So I'm going to go to this most jacked up pose here and make and replace and let's take the value to 03:26.100 --> 03:26.490 one. 03:26.940 --> 03:32.730 And as soon as I start painting and see it has a huge effect and it moves the vertices in a pretty big 03:32.730 --> 03:33.390 direction. 03:33.480 --> 03:33.960 All right. 03:34.260 --> 03:38.310 And that's this is just really rough just to show you how the tools work. 03:38.580 --> 03:41.280 So I'm going to go back to smooth and then flood this. 03:41.280 --> 03:44.370 And you can see how it greatly smooths out this region. 03:44.370 --> 03:44.700 Right. 03:45.160 --> 03:46.230 Makes it much more smooth. 03:46.230 --> 03:47.580 So let's deal with the armpit here. 03:48.000 --> 03:55.860 We can actually take the replace tool and actually go to a value of zero to kind of erase these values. 03:56.310 --> 04:02.070 But the opposite of of what you would expect to happen is happening where you can see that the instead 04:02.070 --> 04:06.060 of going back into the body, these vertices are going further away. 04:06.060 --> 04:07.380 They're going up to the bicep. 04:07.710 --> 04:12.510 So that gives us an indication that when we're painting a zero on this, it has to replace that value 04:12.510 --> 04:18.660 with something and it's replacing it with a joint that is already having some kind of influence on it. 04:18.660 --> 04:20.430 And now it's just giving it greater influence. 04:21.360 --> 04:23.670 The more we tell it, the shoulder is zero. 04:23.970 --> 04:25.080 It has to replace it with something. 04:25.080 --> 04:27.000 So now it's what my guess is. 04:27.000 --> 04:28.200 It's saying the bicep. 04:28.200 --> 04:30.240 Now the bicep is getting more influence. 04:30.660 --> 04:34.290 So now we can go to the left arm bone and see if that's the case. 04:34.290 --> 04:38.310 Then we can see that is so now we can actually do a zero on this. 04:38.310 --> 04:40.440 And what you would expect is happening now. 04:40.860 --> 04:43.110 The armpit is going back into the body. 04:43.800 --> 04:52.140 So this is kind of one way to troubleshoot and see how the joints are affecting the skin and the weights. 04:52.470 --> 04:58.380 So now we have, you know, decent kind of situation here and we can smooth this out as well. 04:58.380 --> 04:59.220 Unclick smooth and. 04:59.340 --> 05:05.570 Flood this out, but the shoulder is still a little wonky and there's a very interesting tool that we 05:05.570 --> 05:08.000 can use called post space defamations. 05:08.360 --> 05:10.520 So I'm going to get out of the tool settings here. 05:11.390 --> 05:19.580 And with this arm post still up here, we can kind of get an idea of how bad the deformation is. 05:19.880 --> 05:22.010 The shoulder should definitely not look like this. 05:22.010 --> 05:28.310 So let's go back to the default pose and let's select the joint that's going to be influencing that 05:28.310 --> 05:30.950 area, which is the shoulder or this upper arm joint. 05:31.580 --> 05:34.820 And let's go to to form post-paid defamation. 05:35.180 --> 05:40.370 And for this tool to work, we want to make sure that we actually go into our Windows settings and preferences, 05:40.370 --> 05:42.890 plug and manager, make sure the plugin is loaded for this. 05:43.220 --> 05:46.910 So I'll click on that and then you can scroll down to probably near the bottom. 05:47.150 --> 05:49.670 It's called Poes interpolated dot bundle. 05:49.670 --> 05:55.370 You want to make sure these are checked on loaded and auto loaded, so that will make this tool actually 05:55.370 --> 05:55.830 work. 05:56.330 --> 06:00.800 So we need that first setup of the pose editor and we get this new window. 06:00.800 --> 06:03.330 And let's play around with this. 06:03.470 --> 06:07.280 Let's turn on the pose editor and say, create a pose. 06:07.910 --> 06:14.060 And by default, I don't have the the neutral poses being created. 06:14.660 --> 06:17.270 That might not be the case for you. 06:18.590 --> 06:24.650 I did that on mine and I'm having a hard time finding how to get back to the default. 06:24.980 --> 06:28.280 But basically, the default should be that it will create neutral poses here. 06:28.280 --> 06:31.850 If it doesn't, you can just do that from poses ad neutral poses. 06:32.720 --> 06:34.040 So now we have a neutral pose. 06:34.460 --> 06:36.920 So it's basically saying, OK, this is home base. 06:36.920 --> 06:39.320 This is where the headquarters is. 06:39.320 --> 06:43.190 You know, where we're going to always refer back to. 06:43.200 --> 06:45.770 This is a good pose, right? 06:46.050 --> 06:47.660 This is the default neutral pose. 06:48.170 --> 06:52.160 So let's scrub forward and find the jacked up pose, which is up here. 06:52.940 --> 06:57.530 And now we can create a pose to fix this. 06:57.560 --> 07:04.700 OK, and it's basically going to do all of the set driven key stuff we've learned in space can do that 07:04.700 --> 07:07.040 on a defamation level. 07:07.040 --> 07:07.330 Right. 07:07.340 --> 07:09.730 It's going to set up all that stuff behind the scenes. 07:09.740 --> 07:11.300 We don't have to touch any of that stuff. 07:11.810 --> 07:15.330 So let's create a pose with the joint selected. 07:15.380 --> 07:20.760 We'll go to poses add pose and open up the option box and all. 07:20.780 --> 07:21.320 That's fine. 07:21.320 --> 07:25.340 We'll say add pose and now we get the option to name the pose. 07:26.060 --> 07:29.870 I'll just say Shoulder Fix is the name of this. 07:30.350 --> 07:33.770 And this is an important defamation order thing here. 07:33.770 --> 07:34.090 Right? 07:34.400 --> 07:37.990 So if we say automatic, it may or may not choose the right one. 07:38.270 --> 07:45.920 So this is a very important menu and you might need to play around with this, because when I have been 07:45.920 --> 07:52.220 testing this, I get some very undesirable and useless results when I choose the wrong one. 07:52.610 --> 07:57.980 But in general, the way you want to think about this is what is the order of defamations that I would 07:57.980 --> 07:58.280 like. 07:58.640 --> 08:04.020 I would like no one for the bones to deform the geometry. 08:04.070 --> 08:04.830 That's number one. 08:05.360 --> 08:07.760 Number two, I want to correct that. 08:08.210 --> 08:08.740 Right. 08:08.750 --> 08:10.730 I want to correct that deformation. 08:10.730 --> 08:12.250 So that has to happen after it. 08:12.300 --> 08:12.740 All right. 08:13.010 --> 08:16.910 So we need to choose something that's like post or after. 08:16.940 --> 08:20.400 I've figured out that for this example, after works. 08:20.400 --> 08:21.890 So I'm going to say create pose. 08:23.090 --> 08:30.800 Now we get this edit button is turned on, it's red and we can see it's named after the joint. 08:31.340 --> 08:38.790 And what this means is isn't currently with this edit button on, we can select the bound mesh to that 08:38.790 --> 08:41.390 joint and affect it and change it. 08:41.390 --> 08:46.750 And it will remember it based on the pose of this joint that's affecting it. 08:46.790 --> 08:54.590 OK, so I'm in the sculpting tools and I'm just going to quickly try to fix this a little bit. 08:54.590 --> 09:01.460 I'm going to bring up the shoulder, bring in the armpit, and this is going to be very, very rough. 09:02.120 --> 09:10.040 I'm just going to go in here and hold down B and middle mouse drag, try to smooth this stuff out just 09:10.040 --> 09:12.830 a touch and bring up the center. 09:13.730 --> 09:16.340 Same thing on the sides here. 09:16.340 --> 09:17.960 I just want to bring all this stuff up. 09:21.250 --> 09:27.970 And then I can go through and smooth it real quick, holding down shift, if you've watched the first 09:27.970 --> 09:32.550 part of this course, you will have some knowledge of the sculpting tools. 09:33.430 --> 09:40.690 So for the most part, this looks about a million times better already, just in that couple of seconds 09:40.690 --> 09:44.690 of, you know, messing with this pose. 09:45.580 --> 09:52.660 So what we can do is save this by turning off editing here and click this button. 09:52.660 --> 09:54.850 So I'm going to say stop editing when I click that. 09:55.130 --> 10:00.940 OK, so what it's going to do as we scrub back through it should remember all of those changes we've 10:00.940 --> 10:01.390 made. 10:01.690 --> 10:06.760 So any time that the arm gets back into that pose, it's going to fix it. 10:06.760 --> 10:09.310 And it feels like there's muscle here, right? 10:09.310 --> 10:17.410 It feels like there's a trap trap trapezius go with this muscles and the deltoid here. 10:17.890 --> 10:18.310 Right. 10:18.460 --> 10:20.290 It feels more fleshy. 10:20.290 --> 10:21.520 And this is organic. 10:21.520 --> 10:24.630 And there's things moving under the skin like muscles and bones. 10:25.000 --> 10:33.070 So this is a really, really cool way to build and these defamations into the rig so that they'll happen 10:33.070 --> 10:35.980 every time you animate the character and those poses. 10:36.700 --> 10:37.070 Cool. 10:37.570 --> 10:38.880 Thanks for watching this video. 10:38.890 --> 10:44.170 And in the next lesson, we all jump back into finishing up rigging bones. 10:44.380 --> 10:50.070 So we'll have a animated character that we can use in the later part of this course. 10:50.110 --> 10:50.800 Thanks for watching.
