1 00:00:05,890 --> 00:00:11,350 All right let's go ahead and take a look at the hair particle system and the hair particle system can 2 00:00:11,350 --> 00:00:17,300 be used for many many things including obviously the hair for your character. 3 00:00:17,470 --> 00:00:23,130 You can use it for fur on animals for your rug for the carpet. 4 00:00:23,250 --> 00:00:30,760 A sweater has you know lint on it or a little hair particles on it you can use a hair particle for any 5 00:00:31,150 --> 00:00:37,850 of that kind of stuff that you could think of that would have some kind of hair or fur on it. 6 00:00:38,200 --> 00:00:41,700 So let's take a look at the different options and settings that we have. 7 00:00:41,830 --> 00:00:48,120 If we go ahead and x to delete this shift and mash U-V sphere. 8 00:00:48,700 --> 00:00:57,400 Now going to the particle system or a new particle new and let's change it from emitter to hair. 9 00:00:57,430 --> 00:00:57,760 All right. 10 00:00:57,790 --> 00:00:58,630 Awesome. 11 00:00:58,630 --> 00:01:00,310 Now keep in mind as well. 12 00:01:00,400 --> 00:01:06,370 If I had zero to go into camera view and this is something keep in mind for the last Torrijos for the 13 00:01:06,370 --> 00:01:13,870 last tutorial and any other tutorial really if I hit 12 right here you can see it looks like that which 14 00:01:13,870 --> 00:01:18,990 looks kind of terrible it's looks like a bunch of tiny little cylinders sticking out. 15 00:01:19,060 --> 00:01:26,200 The reason for that is because we are in the blender renderer which is the old engine of rendering that 16 00:01:26,200 --> 00:01:27,730 is kind of outdated. 17 00:01:27,940 --> 00:01:34,390 So always make sure that your are in cycles render if you're going to be rendering things and you can 18 00:01:34,390 --> 00:01:42,130 see that for the most part the options are pretty much the exact same thing over here now and we have 19 00:01:42,130 --> 00:01:45,410 a couple of other options like the cycle's hair rendering right here. 20 00:01:46,230 --> 00:01:52,780 If we have 12 now and cycles render you can see that we get a much softer nicer result. 21 00:01:52,780 --> 00:01:58,450 So for your emitter as well when you're going to be rendering make sure you're in cycles render. 22 00:01:58,480 --> 00:02:00,160 For that matter. 23 00:02:00,250 --> 00:02:00,480 All right. 24 00:02:00,490 --> 00:02:04,250 I'm going to hit escape to close that off because it's taking too long. 25 00:02:04,410 --> 00:02:07,360 And now let's take a look at the different options that we have here. 26 00:02:08,080 --> 00:02:13,820 First of all let's select advance because all the options are most of them are under this tab anyways 27 00:02:14,470 --> 00:02:16,960 and right here the number amount. 28 00:02:16,960 --> 00:02:25,650 Can you guess what that does the number amount is obviously the number of hairs in our mesh. 29 00:02:25,780 --> 00:02:28,710 Hair length is the length of our hair. 30 00:02:28,990 --> 00:02:30,930 I mean I'm kind of stating the obvious here. 31 00:02:30,940 --> 00:02:31,910 I know but. 32 00:02:32,110 --> 00:02:40,120 And then the image is you could choose vertices or faces just like our emitter particle system and the 33 00:02:40,120 --> 00:02:45,530 distribution whether it's random or jittered or hasn't even distribution or not. 34 00:02:46,530 --> 00:02:52,440 All right down here we have a hair dynamics which is really cool if we hit all day. 35 00:02:52,740 --> 00:02:54,280 You can see nothing happens. 36 00:02:54,390 --> 00:03:02,250 Now hair dynamics what that does is just like before when we had added a physics rigid body to our cubes 37 00:03:02,560 --> 00:03:03,070 here. 38 00:03:03,090 --> 00:03:11,430 You can add you can make your hair so that it's dynamic and basically interacts within itself and acts 39 00:03:11,520 --> 00:03:15,220 like hair basically just like with our cloth simulator. 40 00:03:15,450 --> 00:03:24,720 So if I knew if I enable this and hit all a you can see that now we have a nice long flowing hair. 41 00:03:25,170 --> 00:03:26,070 Pretty cool. 42 00:03:26,220 --> 00:03:29,200 And you can grab the ball and move it around of course. 43 00:03:29,550 --> 00:03:33,220 This is like the Baywatch sphere over here. 44 00:03:33,240 --> 00:03:36,190 We got our nice flowing mane of hair. 45 00:03:37,060 --> 00:03:39,350 All right going to close and stop the animation. 46 00:03:39,490 --> 00:03:44,770 And here we have all the different options that we had looked at before which pretty much do the same 47 00:03:44,770 --> 00:03:49,710 kind of result for the hair as they did for the cloth simulator. 48 00:03:50,620 --> 00:03:55,150 Now we are the velocity which is just like we had seen before. 49 00:03:56,060 --> 00:04:05,960 Emits it or makes it longer on the normal velocity and we could choose which access it's going in if 50 00:04:05,960 --> 00:04:07,850 we choose to do so. 51 00:04:08,300 --> 00:04:16,220 Over here we have random which will basically twist and turn them in a random direction and in a random 52 00:04:16,220 --> 00:04:17,020 way. 53 00:04:17,630 --> 00:04:25,420 And the object tangent and rotation don't do anything for now because of the settings that we have although 54 00:04:25,420 --> 00:04:37,230 tangent does kind of it basically gives a different rotation than its starting rotation where it's just 55 00:04:37,250 --> 00:04:40,310 protruding protruding straight out of the mesh. 56 00:04:41,550 --> 00:04:47,700 Over here we have rotation which rotation actually won't do anything right now but we will take a look 57 00:04:47,700 --> 00:04:51,780 at how we can use this option for something else that is pretty cool. 58 00:04:52,720 --> 00:04:59,320 Under here we have the physics tab and here again if you press these you're going to think that's not 59 00:04:59,320 --> 00:05:03,670 really doing much although the Brownian definitely does something. 60 00:05:03,820 --> 00:05:07,170 But for example the drag you could see it's not doing anything. 61 00:05:07,300 --> 00:05:12,980 And this does do something but it will be when the hair dynamics is enabled. 62 00:05:13,150 --> 00:05:21,480 And if you hit Alt A This will be basically the amount of air drag on there which we cannot see. 63 00:05:22,170 --> 00:05:27,480 While it's just stationary and still over here we have the size. 64 00:05:27,490 --> 00:05:34,270 So this basically as you can see would be the size when we increase our object here not doing anything. 65 00:05:34,270 --> 00:05:41,500 But again we will take a look at that how it affects our mesh later and this is the random size which 66 00:05:41,500 --> 00:05:47,950 we will use with the particle for something else in just a bit or in the next tutorial but we could 67 00:05:47,950 --> 00:05:55,030 definitely use the Brownian which basically gives our hairs so that they're not completely straight. 68 00:05:55,030 --> 00:06:02,200 You can see that right here they're just straight boom the Brownian basically curls it up and gives 69 00:06:02,200 --> 00:06:12,440 it more of a twisted look so it's not just a straight strand So pretty cool with the Brownian now we 70 00:06:12,440 --> 00:06:19,040 have down here of course we have the die on head etc. like we saw before. 71 00:06:19,310 --> 00:06:23,330 Down here we have the display. 72 00:06:23,340 --> 00:06:28,390 No I want to go to the children so the children here are pretty cool. 73 00:06:28,440 --> 00:06:34,830 And the simple one is actually not the best one to use because simple what it does is it clumps it together 74 00:06:34,830 --> 00:06:36,060 so simple. 75 00:06:36,240 --> 00:06:39,910 And I'm actually going to turn the Brownian down to zero so you could see it better. 76 00:06:39,990 --> 00:06:46,900 The symbol will take one strand and then add the children's strands right next to it so will clump 10 77 00:06:46,920 --> 00:06:56,280 other particle strands around that one strand which can look good but it looks a little clomped interpolated 78 00:06:56,610 --> 00:07:04,860 basically interprets it or takes one strand and then another and then fills out the in-between with 79 00:07:04,860 --> 00:07:05,460 the children. 80 00:07:05,460 --> 00:07:13,960 So it's much more evenly distributed and between the two strands right here we have the display. 81 00:07:13,960 --> 00:07:17,430 So the display is set at 10 but render is set at 100. 82 00:07:17,580 --> 00:07:24,810 So it will actually render out 100 of these so that would look like this which is a lot. 83 00:07:24,950 --> 00:07:30,580 So I'm going to turn this back down to 10 so that doesn't break my computer and I'm going to turn the 84 00:07:30,580 --> 00:07:38,590 Brownian back up because I do want some some randomness to it. 85 00:07:38,620 --> 00:07:41,350 And for it to not look completely straight. 86 00:07:41,350 --> 00:07:45,580 All right and then we have all the different options here which are basically kind of the same as the 87 00:07:45,580 --> 00:07:49,000 other ones but this one these ones affect the children 88 00:07:51,450 --> 00:07:54,330 closing that we have the field weights here of course. 89 00:07:54,330 --> 00:08:02,270 And for example again these will be in effect when you actually put the head dynamics or dynamics on. 90 00:08:02,490 --> 00:08:12,360 You can see if I hit gravity nothing happens but if we go ahead and turn on the head dynamics hit all 91 00:08:12,400 --> 00:08:17,660 of a you can see that right now the hair is falling. 92 00:08:17,660 --> 00:08:24,110 Once I reset my animation back to the beginning you can see that the hair is falling down. 93 00:08:24,120 --> 00:08:31,170 However if I turn the gravity off reset it you can see that the hair is no longer falling because there 94 00:08:31,170 --> 00:08:32,290 is no gravity. 95 00:08:32,400 --> 00:08:34,610 Pretty self-explanatory. 96 00:08:34,830 --> 00:08:41,110 So again those would take into effect when you have the hair dynamics on. 97 00:08:41,610 --> 00:08:48,030 And we have the wind factor and all the other ones for the force the Forsett forcefield that we want 98 00:08:49,360 --> 00:08:51,350 here we have some forcefield settings. 99 00:08:51,550 --> 00:08:56,050 Virtex groups here you could determine the density of it the length of it. 100 00:08:56,050 --> 00:09:02,680 So if you want for example hair to only be on the side of the sphere you would at a vertex group and 101 00:09:02,680 --> 00:09:08,600 assign these vertices to it and then select that vertex group from here. 102 00:09:08,950 --> 00:09:14,740 And then there would only be hair sticking out from that vertex group or more density on that vertex 103 00:09:14,740 --> 00:09:15,440 group. 104 00:09:15,460 --> 00:09:16,190 Pretty cool. 105 00:09:16,990 --> 00:09:24,100 And then here we have custom properties textures and the cycle's hair rendering Tabaret here. 106 00:09:24,190 --> 00:09:29,800 Now what we want to take a look at is how this is rendering so far. 107 00:09:30,040 --> 00:09:36,670 I'm going to go ahead and go to a file user preferences system and turn on my graphics card rendering 108 00:09:36,670 --> 00:09:45,250 by selecting my graphics card here and then going to the render tab and selecting sheepy you now going 109 00:09:45,250 --> 00:09:47,260 back here if ii. 110 00:09:47,950 --> 00:09:51,430 I'm also going to turn the children down a little bit. 111 00:09:51,580 --> 00:10:00,820 So under children which is right here I can turn the render down to 20 that zero to go on camera view 112 00:10:00,910 --> 00:10:06,020 let's I'm actually going to scale that hair down a little bit. 113 00:10:06,250 --> 00:10:13,180 So the hair length let's bring it in looks a little all over the place. 114 00:10:13,980 --> 00:10:22,820 And I non-normalized Well all right zoom out a bit and 12 to render. 115 00:10:22,820 --> 00:10:26,590 See how our hair ball looks like. 116 00:10:27,020 --> 00:10:31,150 And I'm going to pause it quickly and let this render out. 117 00:10:32,290 --> 00:10:34,720 All right so that's what it's looking at. 118 00:10:34,730 --> 00:10:39,260 Pretty interesting except it's kind of gray on gray background. 119 00:10:39,380 --> 00:10:43,180 So what we can do is hitting F 11 to go back here. 120 00:10:43,280 --> 00:10:49,730 We can actually add a material to our hair particle system going to the material tab. 121 00:10:49,850 --> 00:10:56,660 Let's click on new and let's make it while you can make it whatever color you'd like going to make it 122 00:10:56,660 --> 00:10:59,390 red and then hit 12. 123 00:10:59,390 --> 00:11:03,000 Once again to render it out. 124 00:11:03,050 --> 00:11:08,050 All right so that is how our hair ball is looking pretty interesting. 125 00:11:08,050 --> 00:11:12,700 It looks like a ball of yarn that went crazy. 126 00:11:12,700 --> 00:11:18,610 In fact I could see this thing with a pair of eyes and a pair of teeth for sure. 127 00:11:18,610 --> 00:11:19,270 All right. 128 00:11:19,270 --> 00:11:20,790 Now let's go over here. 129 00:11:21,710 --> 00:11:29,070 Let's go back to the particle system and down here we have a couple other options. 130 00:11:29,080 --> 00:11:33,340 If we look at this and it might be hard because it's a little messy so I might have to tone it down 131 00:11:33,340 --> 00:11:34,500 a little bit. 132 00:11:34,570 --> 00:11:40,440 Ray your route thickness is basically the thickness of the root of the hair. 133 00:11:40,510 --> 00:11:47,020 As a name would imply if I turned this down and you might not see it here because it's actually not 134 00:11:47,020 --> 00:11:51,200 going to affect it it's not going to affect it. 135 00:11:52,300 --> 00:11:58,510 With the strands here but in the render if I change the root and I'm going to exaggerate it like crazy 136 00:11:59,160 --> 00:12:08,340 to let's say 70 now let's even go not that much maybe 30. 137 00:12:08,340 --> 00:12:19,540 If I go back to my render tab and render it out you will see that the root of it is much thicker. 138 00:12:19,670 --> 00:12:26,900 So it gives a really interesting and cool result now actually because now instead of just being a thin 139 00:12:27,170 --> 00:12:34,610 tiny piece of hair which looks like you know a piece of string which I guess hair would look like that 140 00:12:34,610 --> 00:12:38,390 but it looks kind of stiff. 141 00:12:38,440 --> 00:12:46,330 And and yeah very very sharp here it's more clumped together. 142 00:12:46,330 --> 00:12:49,890 And of course the root is a lot thicker. 143 00:12:49,900 --> 00:12:53,350 So you can see we're getting a pretty interesting result. 144 00:12:53,350 --> 00:12:56,140 In fact it looks I don't know. 145 00:12:56,150 --> 00:13:01,540 I mean I mean I like abstract artwork I don't know about you but this looks pretty cool to me. 146 00:13:01,540 --> 00:13:04,570 You can get some pretty cool interesting looks to this. 147 00:13:04,570 --> 00:13:07,870 And of course if you were to animate it that would be even cooler. 148 00:13:07,870 --> 00:13:13,500 All right going to escape to close that off and then adding F 11 to go back. 149 00:13:13,720 --> 00:13:14,870 So that's the route. 150 00:13:14,950 --> 00:13:19,230 And of course the tip does the same thing for the tip. 151 00:13:19,240 --> 00:13:26,200 So if I increase this you can see that again and the viewport doesn't do anything. 152 00:13:26,650 --> 00:13:36,730 But if I go back to here hit F 11 to go back to our render tab and by the way you could render different 153 00:13:36,730 --> 00:13:42,870 images in different slots and basically the way that you do that is going over here. 154 00:13:42,940 --> 00:13:49,840 Once again you could choose which slot that you want to render And so you could have different slots 155 00:13:49,840 --> 00:13:53,620 to compare your pictures are going to get to slot three hit F 12. 156 00:13:54,790 --> 00:13:57,160 To render that and just show you what it looks like. 157 00:13:57,230 --> 00:14:07,430 Of course you might have guessed the tape will increase the tip of the of of the particle or the particle 158 00:14:07,730 --> 00:14:10,260 and the children of it. 159 00:14:11,450 --> 00:14:13,790 So you could see kind of a difference between these two. 160 00:14:13,790 --> 00:14:17,010 Here the tape is thinner and here it's thicker. 161 00:14:17,430 --> 00:14:21,400 And here we just have strands all the way through. 162 00:14:21,400 --> 00:14:21,840 All right. 163 00:14:21,860 --> 00:14:24,820 So right here also you could make it close the tip. 164 00:14:24,830 --> 00:14:32,810 So it will basically even if the tip is increased like here. 165 00:14:33,920 --> 00:14:36,800 It will tapered off into a closed shape. 166 00:14:36,800 --> 00:14:48,090 So until like a law pointed tip if I take this off you will see that the tips won't be closed off and 167 00:14:48,090 --> 00:14:56,000 it will actually be kind of a empty open a cylindrical shape as you can see here. 168 00:14:56,130 --> 00:14:59,490 It's just a cylinder which is open and it's not closed off. 169 00:14:59,490 --> 00:15:03,490 So it gives it a very interesting and strange result. 170
