WEBVTT 00:00.510 --> 00:03.930 Welcome to fracturing with the grease pencil. 00:04.260 --> 00:06.350 So this is all about manual destruction. 00:06.360 --> 00:12.470 But this time with drawing which gives us even more control over how the object will fracture. 00:12.600 --> 00:20.100 Now this probably is about as manual as you want to get before it starts getting to owner risk to do 00:20.100 --> 00:21.010 anything. 00:21.220 --> 00:26.070 Okay so in a few moments we're going to show you how to set up the grease pencil to work with the fracture 00:26.070 --> 00:29.430 tool because if you just use it by default it won't work. 00:29.430 --> 00:35.550 There's one setting that we've got a nail and then we're going to be using the grease pencil for fracture 00:35.550 --> 00:36.510 guides. 00:36.510 --> 00:39.630 So let's go hop straight on over in a blender. 00:39.960 --> 00:44.820 Okay so before we jump in and start scribbling over our model with the greasepaint So we need to make 00:44.820 --> 00:46.750 sure we've got a few things ready. 00:46.860 --> 00:50.060 First of all I want a campus to be able to draw on. 00:50.070 --> 00:56.190 And this cube is not going to be quite right for me so I'm going to scale it on the z axis by point 00:56.190 --> 01:02.270 1 so it's nice in then on the scale again on the without being on the z axis. 01:03.060 --> 01:03.940 Though get eight. 01:03.960 --> 01:05.900 That's plenty big enough. 01:06.090 --> 01:11.950 I'm also going to apply the scale at this point with the right set of keys control and a scale. 01:12.210 --> 01:13.000 Perfect. 01:13.170 --> 01:18.630 So before we start scribbling on it we need to open up a 3D editor properties panel go down to where 01:18.630 --> 01:24.510 it's his grease pencil and we need to change this to objects so that the grease pencil and the fracture 01:24.510 --> 01:26.610 tool talked to one another. 01:26.700 --> 01:26.940 Right. 01:26.940 --> 01:32.370 So let's get rid of the tool shelf zoom around to the top and the properties window then that's gone 01:32.370 --> 01:33.070 as well. 01:33.210 --> 01:36.620 Orthographic projection viewed from the top. 01:36.630 --> 01:37.370 Perfect. 01:37.480 --> 01:39.460 And also going to get rid of the time line here. 01:39.470 --> 01:40.840 It's just not needed. 01:40.920 --> 01:44.790 So let's start by just drawing a single line. 01:44.790 --> 01:46.270 I'm holding down the d key. 01:46.320 --> 01:48.610 Grease pencils a single line. 01:48.610 --> 01:53.690 I open up the cell fractured soul go to greasepaint So I'm not going to change any other settings. 01:53.700 --> 01:55.510 And let's see what happens. 01:55.980 --> 01:57.820 Okay so it looks like. 01:59.000 --> 02:04.140 Excellent so the splintering seems to almost be perpendicular. 02:04.150 --> 02:09.440 Come I'm calling it splintering here the fracturing seems to be almost perpendicular to that particular 02:09.440 --> 02:11.270 line that I drew. 02:11.660 --> 02:18.650 Okay so let's just undo that and see what happens with three lines saying to draw one line on this side 02:18.680 --> 02:20.950 and one line on this side. 02:21.140 --> 02:22.850 And let's do the same thing again. 02:22.850 --> 02:25.560 Space enter grease pencil. 02:25.580 --> 02:27.400 Okay. 02:28.280 --> 02:35.000 Okay excellent So what we're seeing here is the grease pencil itself isn't drawing where the fractures 02:35.000 --> 02:35.860 are going to be. 02:35.870 --> 02:37.740 That's quite important. 02:37.790 --> 02:41.960 It's drawing a line guiding where the fractures are going to be. 02:41.960 --> 02:45.680 So the fractures aren't necessarily following this exact path. 02:45.680 --> 02:50.650 Let's go back to where those lines are so we can see them to a line here. 02:50.690 --> 02:52.600 Line here the line here. 02:52.640 --> 02:58.820 In fact just so we know what's going on I'm going to go to the scene settings and read draw these lines 02:59.090 --> 03:05.430 just so we can see them as well roughly as they are when we go over to our other objects. 03:05.540 --> 03:09.700 So over here so we can see what's going on select everything. 03:09.710 --> 03:18.450 All there we get so we can see here that it splits between these lines almost equally. 03:18.750 --> 03:23.570 Okay so what happens if we join this line up perhaps with a spiral or a circle. 03:23.570 --> 03:25.060 Let's try that. 03:25.070 --> 03:30.920 So this point I'm just going to get rid of those points completely and on the object I'm going to make 03:30.920 --> 03:34.880 sure I'm on the right object here so we can actually select that thing just get rid of it that's probably 03:34.970 --> 03:39.680 be the quickest way rather than just the leting it going to go back round to the top. 03:39.680 --> 03:44.090 Orthographic I'm just going to delete the grease pencil I've already done on the objects and making 03:44.090 --> 03:45.410 sure it's his object. 03:45.410 --> 03:48.010 Let's draw some concentric circles. 03:48.790 --> 03:49.870 So one. 03:50.670 --> 03:51.720 Soo. 03:52.470 --> 03:54.430 The re I'm just driven. 03:54.440 --> 03:58.470 Draw an absolute squiggle down the side there and see what happens. 03:58.500 --> 04:03.290 You know this is one of these things where experimentation is going to reward you now because we've 04:03.290 --> 04:05.400 got a few other bits to break up. 04:05.400 --> 04:08.060 I'm going to turn that up to maybe 200. 04:08.130 --> 04:10.190 So there can be more shards. 04:10.980 --> 04:12.240 How about that. 04:12.270 --> 04:15.080 We've actually got shattering happening in a circle. 04:15.210 --> 04:20.240 Now you may notice that when glass breaks sometimes it breaks in that type of pattern. 04:20.370 --> 04:26.700 Again if you are trying to emulate something from the real world I would strongly recommend you're using 04:26.700 --> 04:28.110 reference material. 04:28.140 --> 04:30.750 Let's go have a look at how that looks. 04:30.750 --> 04:31.900 That is awesome. 04:31.920 --> 04:36.470 So I could just imagine something has impacted this bang in the middle there. 04:36.480 --> 04:38.810 So let's make sure once again. 04:38.890 --> 04:43.130 Well I'm going to say let's make sure I'm probably not going to correct it at this point in time. 04:43.230 --> 04:47.940 But let's check and see how this behaves when you apply physics to it. 04:47.970 --> 04:54.060 So just going to apply active body with no gravity whatsoever and basically make sure it doesn't throw 04:54.060 --> 05:00.510 itself for parts because if you're starting from a model that spontaneously explodes on you and by the 05:00.510 --> 05:05.880 way it's not I know the timeline's not here but with Oulton a we can see it's running through just here. 05:06.090 --> 05:08.680 So that is already a great start. 05:08.790 --> 05:11.250 Now of course we can have a bit of fun with that. 05:11.250 --> 05:18.470 We can literally let's add something else to the scene rather than playing about so in object mode. 05:18.480 --> 05:24.990 I'm going to add in a what shall I had Eevee sphere almost like a ball hitting it and then give that 05:25.050 --> 05:26.400 active as well. 05:26.400 --> 05:31.160 And then I can literally just lower it in there and smash just comes through. 05:31.170 --> 05:34.100 How cool is that sauce. 05:34.380 --> 05:35.450 Okay guys. 05:35.490 --> 05:37.390 That's it for the grease pencil. 05:37.390 --> 05:39.480 Have lots of fun with it. 05:39.480 --> 05:45.600 Remember to share your particular work what did you come up with when you played with this boom. 05:45.660 --> 05:47.820 Oh it's just research. 05:48.510 --> 05:50.860 I love it without with Lawyer. 05:51.090 --> 05:51.590 Okay. 05:51.660 --> 05:52.610 I stopped doing that. 05:52.610 --> 05:59.880 Now remember to show your work over on the forums and I will see you guys pile on a move too quick in 05:59.880 --> 06:01.190 the next lecture.
