1 00:00:06,130 --> 00:00:14,170 All right let's take a look at how to make a flag simulation using the cloth the cloth physics tab. 2 00:00:14,170 --> 00:00:20,470 Also we're going to be using Virtex groups and taking a look at new something new called the for the 3 00:00:20,470 --> 00:00:26,080 force fields options and I'm trying to remember everything we're going to cover in this video. 4 00:00:26,200 --> 00:00:28,160 So always learning something new. 5 00:00:28,180 --> 00:00:33,430 We're going to be looking at force fields here and how we can use them with the other two things. 6 00:00:33,430 --> 00:00:35,660 All right deleting our default cube. 7 00:00:35,710 --> 00:00:40,840 Let's go ahead and delete that hit shift day and let's add in a mesh plane. 8 00:00:41,700 --> 00:00:48,210 Grabbing it up let's hit r to rotate x 90 degrees. 9 00:00:48,320 --> 00:00:53,580 Now hitting tab to go into Edit Mode w subdivide. 10 00:00:54,030 --> 00:01:02,330 Subdivide this a couple of times and then hitting s to scale in edit mode still and then as an X to 11 00:01:02,330 --> 00:01:10,700 scale along the x axis go ahead and bring it up. 12 00:01:10,940 --> 00:01:21,860 And now hitting shift day adding a mesh cylinder we're going to add the pole for the flag. 13 00:01:21,990 --> 00:01:26,400 We're going to keep it pretty simple because we're going to focus mainly on the simulation and the wind 14 00:01:26,430 --> 00:01:28,360 and the VOR the force field. 15 00:01:28,590 --> 00:01:33,010 But let's go ahead and at least add a Polen for our flag. 16 00:01:33,120 --> 00:01:44,200 Let's hit smooth shading and then as Z scale on the z axis as Z and then s shift Z to scaley on all 17 00:01:44,200 --> 00:01:48,550 of them except the z axis and bring it to there. 18 00:01:48,790 --> 00:01:57,480 Now selecting this I'm going to hit G and Z and bring it up and scale it down just a tiny bit 19 00:02:02,750 --> 00:02:05,170 and get and bring it higher as well. 20 00:02:06,400 --> 00:02:06,880 All right. 21 00:02:06,880 --> 00:02:10,880 Now let's select our plane go to the physics tab. 22 00:02:10,930 --> 00:02:15,220 This little bouncy ball right here and click on clock. 23 00:02:15,450 --> 00:02:19,910 If we hit all day obviously we can see nothing is happening. 24 00:02:19,930 --> 00:02:23,700 So what we want to do is go ahead and add in the wind. 25 00:02:23,740 --> 00:02:26,420 Now how do we add in the wind. 26 00:02:26,620 --> 00:02:29,110 Well it's pretty simple. 27 00:02:29,110 --> 00:02:33,880 And before we add in the wind let's actually go ahead and do the vertex group part of it. 28 00:02:33,880 --> 00:02:40,480 What I wanted to do is I want it to be attached right here on this corner and the top corner here. 29 00:02:40,750 --> 00:02:46,480 So I want these two corners to not be moving so that it seems like it's attached to this pole right 30 00:02:46,480 --> 00:02:50,730 here the way we do that is via the pinning group. 31 00:02:50,770 --> 00:02:56,830 So the pinning is basically it's going to pin those vertices down and the group is going to be which 32 00:02:56,830 --> 00:02:59,290 vertices it's going to pin down. 33 00:02:59,350 --> 00:03:03,730 If we had to have to go into Edit Mode go to our Virtex groups. 34 00:03:03,850 --> 00:03:10,110 Let's go ahead and add in a new vertex group double click on the name to rename it to flag. 35 00:03:12,770 --> 00:03:15,650 And then we're going to slide this vertex right here. 36 00:03:15,890 --> 00:03:19,910 And this one right here and click a sign. 37 00:03:19,910 --> 00:03:26,620 Now going back to our physics tab we click on pinning and select our vertex group flag. 38 00:03:27,790 --> 00:03:35,060 Now if we hit Alt-A you can see that it's being held by those two vertices. 39 00:03:35,130 --> 00:03:40,710 So the two vertices we put on the vertex group are not moving and they're basically pinning down the 40 00:03:40,710 --> 00:03:41,460 cloth. 41 00:03:41,540 --> 00:03:49,700 They're lets also select our cylinder and make it a collision object so that our flag interacts better 42 00:03:50,030 --> 00:03:53,380 with the actual cylinder and doesn't go through it really. 43 00:03:54,550 --> 00:03:57,530 And now we want to add in the wind. 44 00:03:57,670 --> 00:03:59,770 So how do we do that. 45 00:03:59,800 --> 00:04:04,780 Because right now it's just kind of falling kind of anti-climatic and boring. 46 00:04:06,140 --> 00:04:07,490 Nothing is boring in 3D. 47 00:04:07,490 --> 00:04:08,990 I take that back. 48 00:04:08,990 --> 00:04:12,270 All right now let's go ahead and add in the wind. 49 00:04:12,500 --> 00:04:19,100 So for the win it's basically a force field which is also in the physics tab but we have an easier way 50 00:04:19,100 --> 00:04:19,680 to add it. 51 00:04:19,700 --> 00:04:22,010 We don't want to actually add it to any of these. 52 00:04:22,010 --> 00:04:24,160 We want to add it to a new object. 53 00:04:24,410 --> 00:04:31,580 And if we had shift day we could go to this task force field and Blendr has already assigned these force 54 00:04:31,580 --> 00:04:38,270 fields to an empty object so if we grab any of these right here you can see these are different kinds 55 00:04:38,270 --> 00:04:39,190 of force. 56 00:04:39,380 --> 00:04:40,370 Force fields. 57 00:04:40,460 --> 00:04:42,250 We have some very interesting ones. 58 00:04:42,380 --> 00:04:46,710 I suggest just going through them and clicking all the options and seeing what they do. 59 00:04:46,730 --> 00:04:53,830 There's some pretty cool ones like the vortex which spins your object around and out like a tornado. 60 00:04:53,840 --> 00:04:54,850 Pretty cool. 61 00:04:55,010 --> 00:04:56,460 But we're going to be doing. 62 00:04:56,450 --> 00:05:00,340 So go ahead and click on wind add that in. 63 00:05:00,440 --> 00:05:09,170 And now hitting g to grab this and rotating it like so you can see that we have an arrow here and this 64 00:05:09,170 --> 00:05:13,130 arrow dictates where the wind will be blowing out to. 65 00:05:13,130 --> 00:05:16,420 So in this case it's going that way. 66 00:05:16,550 --> 00:05:21,010 All a you can see that nothing is happening. 67 00:05:21,020 --> 00:05:23,450 So what we want to do is increase our size. 68 00:05:23,530 --> 00:05:28,730 I'm going to also drag down and frame so that it loops back faster. 69 00:05:28,760 --> 00:05:36,130 We want to increase the strength right here and you can see that as we increase it the circles are going 70 00:05:36,160 --> 00:05:36,480 out. 71 00:05:36,480 --> 00:05:43,110 So let's increase it way up so that our flag starts blowing in the wind. 72 00:05:44,920 --> 00:05:47,250 Dustin though. 73 00:05:47,450 --> 00:05:48,360 All right. 74 00:05:48,610 --> 00:05:51,840 That song just popped into my mind as I was saying winda. 75 00:05:52,010 --> 00:05:54,660 So now you can see what our flag is doing. 76 00:05:54,710 --> 00:05:56,210 Pretty cool. 77 00:05:56,210 --> 00:05:57,170 It's falling a little bit. 78 00:05:57,170 --> 00:06:03,310 And then it's flowing and the wind looks like this and had smooth shading as well. 79 00:06:03,320 --> 00:06:09,750 Now you want to keep in mind that you want to have a good size to your to your cloth. 80 00:06:09,920 --> 00:06:13,250 For example if I scale it way down 81 00:06:16,730 --> 00:06:24,410 you can see that it will not have the same effect with the wind. 82 00:06:24,420 --> 00:06:29,670 In fact the wind doesn't even pick it up because it is way too small. 83 00:06:29,700 --> 00:06:32,980 So if your wind is not acting as it should be. 84 00:06:33,180 --> 00:06:42,500 Just make sure that you scale up your flag or your cloth to a good size because otherwise if it's too 85 00:06:42,500 --> 00:06:51,220 small it won't even pick up the wind as the calculations for it won't work and needs to be a correct 86 00:06:51,780 --> 00:06:58,480 Blendr units or a certain amount of metres across or yards whatever measurement you're using. 87 00:06:58,510 --> 00:07:00,340 So keep that in mind as well. 88 00:07:00,580 --> 00:07:01,560 And there we go. 89 00:07:01,570 --> 00:07:05,420 That is our little flag simulation right there. 90 00:07:05,440 --> 00:07:06,390 Pretty cool. 91 00:07:06,430 --> 00:07:11,150 And of course we have all the different options that we could take a look at like we did before. 92 00:07:11,160 --> 00:07:19,600 I mean not take a look at that we could change like we had seen before we could select silk see how 93 00:07:19,600 --> 00:07:26,240 that interacts and that is pretty much how you can make a quick little flag animation to it. 94 00:07:26,270 --> 00:07:27,900 Let's do one last thing. 95 00:07:28,060 --> 00:07:31,270 Let's go ahead and add in a texture to this. 96 00:07:31,270 --> 00:07:36,140 So going to the materials tab Let's go ahead and click new. 97 00:07:36,210 --> 00:07:39,070 We're going to go to cycle's render as well. 98 00:07:39,420 --> 00:07:42,620 Use nodes and we're color it says color. 99 00:07:42,630 --> 00:07:50,440 Let's click this little icon and click image texture which is down here. 100 00:07:50,440 --> 00:07:50,910 All right. 101 00:07:50,910 --> 00:07:51,640 And that was click. 102 00:07:51,640 --> 00:08:01,000 Open it see I thought it had disappeared for a second and go to wherever our flag or our image texture 103 00:08:01,000 --> 00:08:02,430 is saved. 104 00:08:02,440 --> 00:08:04,530 I believe mine is in 105 00:08:07,380 --> 00:08:10,640 and we just had to find our image wherever it's saved. 106 00:08:10,860 --> 00:08:14,250 So the flag image that I made quickly is right here. 107 00:08:15,080 --> 00:08:18,860 Open image and now splitting the viewport. 108 00:08:19,810 --> 00:08:26,890 So it also to close these out and go to the U-V image editor over here and hit tab to go into Edit Mode 109 00:08:27,510 --> 00:08:32,340 ADAs select everything and hit you unwrap. 110 00:08:32,530 --> 00:08:39,690 Go to the image down here and click on the image that you just loaded and let's go to the materials 111 00:08:39,690 --> 00:08:41,710 tab so we can see how it looks. 112 00:08:42,300 --> 00:08:43,510 And I'm going to hit you. 113 00:08:43,650 --> 00:08:51,400 Project from view and scale it up like that's all right. 114 00:08:51,400 --> 00:08:52,220 Awesome. 115 00:08:52,390 --> 00:08:54,000 Now going to close this back up 116 00:08:57,200 --> 00:09:00,550 and then let's go into. 117 00:09:01,040 --> 00:09:04,990 Let's actually try like this. 118 00:09:05,050 --> 00:09:10,660 And now you can see that our flag has a a and a texture to it. 119 00:09:10,690 --> 00:09:11,510 Pretty cool. 120 00:09:11,530 --> 00:09:13,360 Blender rocks. 121 00:09:13,630 --> 00:09:18,640 And then of course we could even try this in rendered mode which is going to look a little strange as 122 00:09:18,640 --> 00:09:24,330 it's going to be calculating it every every length of the way so let's go in textured mode. 123 00:09:24,340 --> 00:09:27,370 It's nice because it has some shading to it. 124 00:09:27,370 --> 00:09:32,160 RAZ If you're just in material mode there's not as many shadows that you could see. 125 00:09:32,170 --> 00:09:34,700 That is our final result right there. 126 00:09:34,840 --> 00:09:43,420 And pretty cool of course you could go ahead and make this into a full animation by just you know tweaking 127 00:09:43,420 --> 00:09:50,280 this whole little bit adding some some ropes and some loops to it so that looks a little bit better. 128 00:09:50,500 --> 00:09:55,960 And then go into the render tab and rendering out your flag animation. 129 00:09:56,200 --> 00:09:57,430 So pretty cool. 130 00:09:57,460 --> 00:10:02,800 And once again keep in mind that if you want to increase the quality of it of course you could increase 131 00:10:02,800 --> 00:10:10,110 the steps and subdivided even more so that it has more vertices to play with. 132 00:10:10,110 --> 00:10:17,320 All right so that is how you make a flag or any kind of flowing object like that and how you would use 133 00:10:17,440 --> 00:10:22,600 the winda or the the wind force field. 134 00:10:22,600 --> 00:10:27,850 Now let's take a look quickly before we wrap it up here at the different options. 135 00:10:28,870 --> 00:10:32,340 Also going to undo that as now it's taking way too long. 136 00:10:32,380 --> 00:10:36,760 I'd put the steps back to five so the forcefield options. 137 00:10:36,760 --> 00:10:40,630 Of course we have the strength right here which determines the strength of the wind. 138 00:10:40,660 --> 00:10:47,320 We have the flow down here which basically is the flow velocity or how the wind is flowing around. 139 00:10:47,390 --> 00:10:49,990 Our our flag. 140 00:10:50,500 --> 00:11:01,360 We have the noise here which basically is the amount of variation in the wind and the speed of which 141 00:11:01,360 --> 00:11:08,080 is basically the different seed's means it will have a different noise value to it. 142 00:11:08,080 --> 00:11:12,860 So it's kind of like a randomness to that to the noise. 143 00:11:13,060 --> 00:11:18,400 And then right here these options right here I'm not sure I've actually never used these before. 144 00:11:18,550 --> 00:11:21,250 And so that's pretty much it. 145 00:11:21,250 --> 00:11:26,660 The main one that you're reusing honestly is just the strength and possibly the flow. 146 00:11:26,860 --> 00:11:33,540 But that is the wind or field really really cool and you could have lots of fun with this. 147 00:11:33,550 --> 00:11:34,030 All right. 148 00:11:34,030 --> 00:11:37,930 I'll see you guys in the next tutorial under rocks. 149 00:11:38,000 --> 00:11:38,500 Peace out. 150 00:11:38,500 --> 00:11:39,340 See there. 151 00:11:41,690 --> 00:11:42,210 All right. 152 00:11:42,210 --> 00:11:44,960 You know one of my favorite beaches Bora-Bora. 153 00:11:45,020 --> 00:11:51,030 We should totally have a blender 3D artists get together in Bora-Bora if you're down for that I'll let 154 00:11:51,030 --> 00:11:53,310 you know if that happens in the future. 155 00:11:53,580 --> 00:11:54,900 All right. 156 00:11:54,900 --> 00:11:56,670 You are the creator of your life. 157 00:11:56,730 --> 00:11:59,300 Much like you create in the world of 3-D. 158 00:11:59,310 --> 00:12:05,010 Don't forget that this world is a place where you can create your very own reality as well. 159 00:12:05,010 --> 00:12:09,950 You can't just hit shift plus 8 at a Lamborghini the house or woman of your dream. 160 00:12:10,080 --> 00:12:15,000 But don't forget that you do have power to create whatever you want here as well. 161 00:12:15,000 --> 00:12:24,120 If you decide to I ladies and gentlemen it might not be a shift a that fast but you can create your 162 00:12:24,120 --> 00:12:24,600 reality. 163 00:12:24,600 --> 00:12:30,090 So go out there create the reality you want both within Blendr and in your life. 164 00:12:30,390 --> 00:12:32,190 Ciao for now of La.
