WEBVTT 00:00.450 --> 00:01.140 Welcome to. 00:01.160 --> 00:04.410 Introduction to a sapling in this video. 00:04.410 --> 00:12.720 You'll turn on a sapling and on your learn the fundamentals of suppling understand to save before using 00:12.720 --> 00:19.950 sapling and we'll see why and learn how to prevent blender from crashing when using sapling. 00:20.010 --> 00:23.300 Let's go explore sapling now over in blender. 00:24.180 --> 00:29.260 So the first thing that we need to go and do now is make sure that sapling is turned on. 00:29.400 --> 00:35.750 So you'll find that under file user preferences and go to the add ons tab. 00:36.030 --> 00:38.250 Now we can search for it. 00:38.400 --> 00:41.610 In fact it's here add curve sapling we don't need to search for it. 00:41.640 --> 00:43.240 I've already got it turned on. 00:43.260 --> 00:49.180 If you haven't please put a tick in this box and save your user settings. 00:49.440 --> 00:49.980 Excellent. 00:49.980 --> 00:53.860 Now that saplings turned on we can go and explore with it. 00:54.030 --> 00:59.810 So first of all so we don't muck around with our current blender file the bunny that we're working on. 00:59.880 --> 01:04.370 Let's go explore the sapling add on in a brand new blender file. 01:04.380 --> 01:09.380 Ill also make sure everything's nice and smooth for us and nothing else is slowing us down. 01:09.540 --> 01:15.640 So I'm going to make sure I've saved my fluffy bunny and hop over into a brand new blender file. 01:15.780 --> 01:16.260 Excellent. 01:16.260 --> 01:21.900 So now that we're in a brand new blender far we can go ahead and add half first tree. 01:21.930 --> 01:25.120 So first of all let's get rid of our cube. 01:25.440 --> 01:33.540 Now the sapling add on itself is located under the curves so you can go add curve and add tree or shift 01:33.540 --> 01:41.170 in a curve add tree and it will add a tree forus not quite there yet. 01:41.220 --> 01:43.870 Let's go in and see what else we can do. 01:45.230 --> 01:52.430 Okay solvay expanded the operation panel all the operator panel in the lower left hand corner here so 01:52.430 --> 01:54.580 we can play with some of these settings. 01:54.590 --> 02:00.620 Now when you're going to go into great detail at this point in the course regarding sapling but do have 02:00.620 --> 02:06.030 a play about it's a wonderfully addictive tool for making some wonderful. 02:08.390 --> 02:11.660 Trees and other plants as well. 02:11.660 --> 02:15.930 So we're going to start on the Geometry tab and look at the branch splitting and branch growth. 02:15.980 --> 02:20.870 We're not going to do the leaves or anything else for the moment we just go and deal with these three 02:20.870 --> 02:24.240 sections and a very brief overview of them. 02:24.320 --> 02:31.700 So geometry if we turn the bevel on we can see the the tree becomes three dimensional which is a great 02:31.760 --> 02:35.800 stance and the bevell resolution determines how high. 02:35.840 --> 02:38.400 How many faces this is going to happen at the moment. 02:38.390 --> 02:46.520 Scott 4 I presume this is now 5 6 7 etc. but what you can see is as these increase the number of triangles 02:46.550 --> 02:51.950 also goes up so the higher the resolution the tree the more efforts you are going to have to put into 02:51.950 --> 02:57.770 rendering it as well as the curve resolution doesn't make a difference when it's on vector. 02:57.770 --> 02:59.910 However when it's on auto. 03:00.030 --> 03:07.310 This curve for a solution has a huge difference and it basically controls midspan up here with the curve 03:07.310 --> 03:08.760 resolution set to 1. 03:08.810 --> 03:12.250 You can see that these are really jagged. 03:12.270 --> 03:15.290 But as we turn this up they get smoother and smoother. 03:15.440 --> 03:18.380 But of course that adds more geometry as well. 03:18.380 --> 03:20.210 Random seed will as it sounds. 03:20.210 --> 03:23.210 It starts the tree off in different ways. 03:23.270 --> 03:25.940 A great way of getting a good starting point. 03:25.940 --> 03:32.010 In fact I quite like the one that one there kind of wiggles along as a great start ratio. 03:32.150 --> 03:39.170 Well this is the ratio of the trunk size so that looks more like a dragon's tail or something outside 03:39.170 --> 03:41.810 of World of Warcraft of days gone by. 03:41.900 --> 03:46.010 To be quite honest I can't see that being a tree. 03:46.010 --> 03:47.890 Could be some alien plant though. 03:48.080 --> 03:50.190 Your imagination can run wild. 03:50.210 --> 03:52.450 But that biloela not ever backed down. 03:52.670 --> 03:55.650 Scale of the tree is how high it is solves. 03:55.690 --> 03:59.370 You can make it a whopping great big tree or a tiny tree. 03:59.650 --> 04:04.940 So I'm going to make it a bit smaller so just fits on the screen so we can see the whole tree scale 04:04.940 --> 04:06.320 variation. 04:06.320 --> 04:13.370 The variation in the tree scale so we can turn that up and down and it will make another difference 04:13.910 --> 04:15.410 radius scale. 04:15.430 --> 04:19.350 Well this is going to change the size of the trunk itself. 04:21.420 --> 04:22.760 We want that back. 04:22.770 --> 04:23.500 Here we go. 04:23.640 --> 04:26.800 And the variation will change a variation on that. 04:26.850 --> 04:30.840 So going onto the branch splitting this is where you need to be careful. 04:30.960 --> 04:35.380 I can't stress enough that you will lock blender up at some point whilst playing with this. 04:35.400 --> 04:39.840 So if you're working in a file before you play with sapling please save. 04:39.870 --> 04:45.180 Otherwise there's a good chance that you'll get fed up waiting and will have to quit the program and 04:45.180 --> 04:46.200 start again. 04:46.560 --> 04:55.860 So levels here now these levels going from one to three and will for lock up my computer it might do 04:56.270 --> 04:59.180 be a great example of how not to look at your computer. 04:59.180 --> 05:05.220 Okay I am able to go for in general you probably don't need to go any more than 3 so I'm going to leave 05:05.220 --> 05:10.950 it on too for the moment so we can see what's going on now branches at the moment. 05:10.950 --> 05:13.140 Zero is absolutely fine here. 05:13.140 --> 05:16.890 If we turn this up it's not going to do anything at this moment in time. 05:16.980 --> 05:20.190 The next one means off this main trunk. 05:20.250 --> 05:26.990 There are now 50 branches on the third layer down so 1 2 3 where it's 30. 05:27.000 --> 05:31.040 It means for every every one of these 50 there are 30. 05:31.110 --> 05:37.770 And finally the four effort every one of those attached to those attached to those there's going to 05:37.770 --> 05:39.350 be 10. 05:39.420 --> 05:44.190 Now you can see very quickly cause these are multiplied up you only need to change one of the lower 05:44.190 --> 05:47.150 figures to have a huge impact further down the line. 05:47.310 --> 05:50.520 And that's one of those things that all cost you dearly. 05:50.520 --> 05:51.840 If you go too high. 05:51.860 --> 05:54.990 And trust me I've done it accidentally. 05:55.250 --> 05:56.580 You're just moving the figuring. 05:56.580 --> 06:03.560 Just go to high and the system decides to it's not crashing it's just going to take ages to calculate 06:03.570 --> 06:09.570 the new geometry segment splits are very similar to branches. 06:09.700 --> 06:15.240 Ever let's just lower these down so it limits my chance of crashing. 06:15.240 --> 06:21.960 So we've got 10 branches that are producing 10 branches and that producing 10 branches. 06:21.990 --> 06:22.670 So there we go. 06:22.670 --> 06:24.760 We've got a series of branches coming in off there. 06:24.920 --> 06:27.070 Now other segments splits. 06:27.180 --> 06:34.980 They split the branches themselves but they don't alter these numbers here so if you split up some of 06:34.980 --> 06:40.440 these branches Well it looks of it funky at the moment and I don't think were going to be able to count 06:40.440 --> 06:40.980 them. 06:41.010 --> 06:46.290 There's far too many of them now let's drop back down a couple of levels if and let's drop down to just 06:46.500 --> 06:49.390 level two so we can see what's going on. 06:49.590 --> 06:52.340 So we've got 10 branches coming off of here. 06:52.350 --> 06:56.600 Well it looks it doesn't quite look ten branches but that's what it says. 06:56.820 --> 06:58.650 We got ten branches coming off of here now. 06:58.650 --> 07:00.200 If we splits. 07:00.910 --> 07:02.690 This first level. 07:02.710 --> 07:08.200 We still only have 10 branches coming off of it just splits the first level so is a great way of adding 07:08.200 --> 07:14.380 detail without having to add a load more branches because you're just splitting branches that already 07:14.380 --> 07:15.720 exist. 07:15.750 --> 07:21.670 One of the useful things just go turn up the number here again so we can see more some more tree basically 07:21.970 --> 07:29.790 is the base size and that determines where the actual branches start from at zero or close to zero. 07:29.800 --> 07:37.780 Any way the branches themselves will they start towards the bottom of the tree so that there looks much 07:37.780 --> 07:42.760 more like a Christmas type tree of fir tree. 07:43.090 --> 07:49.020 And of course up the top here a couple of trees that look like that will not look like this. 07:49.040 --> 07:53.740 A couple of ones are like this Acacia trees and things like that. 07:53.830 --> 08:00.910 So there's a lots of different types of tree that you can emulate using this and I would encourage you 08:00.910 --> 08:07.630 to play with the split tangles split angle variation and all of these things here and you'll soon see 08:07.630 --> 08:14.260 that you can make your tree that was once facing up would droop down and have some really weird effects 08:14.260 --> 08:16.130 carrying on with it there. 08:16.520 --> 08:20.000 Okay let's move on to the final section here. 08:20.020 --> 08:21.960 The branch growth. 08:22.060 --> 08:28.390 Now this is where you can really change the dynamic of the tree and you can have a let's say a shorter 08:28.390 --> 08:29.890 stump just here. 08:29.920 --> 08:36.670 Now all of these are relative to the one above as well as very important to realize that point five 08:36.670 --> 08:37.350 and point five. 08:37.350 --> 08:40.990 Well that's half of it was before but point five and 1. 08:40.990 --> 08:49.000 Both of these are now the same length and point five and 2 means that's the actual All these branches 08:49.060 --> 08:55.400 are twice as long as the original stump itself. 08:55.600 --> 08:57.000 Vertical attraction. 08:57.150 --> 09:02.900 Well it simply changes their vertical attraction it literally all looks. 09:02.980 --> 09:04.360 That is quite awesome. 09:04.360 --> 09:05.800 Sorry I have not done that before. 09:05.800 --> 09:08.090 That is quite alien. 09:08.130 --> 09:09.170 It's hypnotic. 09:09.280 --> 09:15.730 Okay that's basically pulls some vertically in a course when they go on over earthcare Looks like it 09:15.730 --> 09:19.120 wraps it round again and then pulls and backup. 09:19.120 --> 09:20.460 So very cool. 09:21.530 --> 09:25.440 And again we've got lots of other things we can work on down here. 09:25.460 --> 09:31.520 In general I don't bother changing the curve for a solution but as you saw earlier it changes the detail 09:31.520 --> 09:37.030 level of the curves and it can actually change the appearance of the tree quite dramatically. 09:37.460 --> 09:43.250 So do play with these sections here and there are a couple of things I want to show you now that you 09:43.250 --> 09:44.860 can actually make. 09:44.940 --> 09:49.150 I have made two things I've made a tree and I've made a little bush wood flowers. 09:49.310 --> 09:53.920 Just to show you how versatile sapling can be. 09:55.540 --> 10:00.770 So here we have the little bush that I have made with some green leaves on it. 10:00.880 --> 10:08.590 I modelled these leaves very quickly using a plain and subdividing it and colouring it in green essentially 10:08.950 --> 10:11.830 and the flowers were there in the nature pack. 10:11.830 --> 10:20.200 I basically just attach them to the vertices at the end of sapling once it was made and of course saplings 10:20.200 --> 10:24.210 more known for its ability to generate a tree. 10:24.220 --> 10:29.530 And here we have a tree in some grass land so you can see the power of it. 10:29.710 --> 10:33.060 And now I've got a challenge for you guys. 10:33.900 --> 10:42.770 I would like you to create a flowering bush so you sapling to create a bush like plants create a basically 10:42.770 --> 10:52.590 leaf to use on our bush convert the sapling curve into a mesh objects using weight painting and virtex 10:52.590 --> 10:57.770 groups to add flowers to the tips and leaves to the bush. 10:58.140 --> 11:03.330 Then we're going to use geometry to make the flowers 3-d. 11:03.870 --> 11:10.140 We're going to make sure that all of your objects have an appropriate material assigned to them. 11:10.140 --> 11:17.300 And just a reminder to save before making any changing in sapling to prevent the loss of data. 11:17.310 --> 11:21.980 Just in case you make one change and it causes blender to crash. 11:22.140 --> 11:25.040 So go ahead and plan out the bush. 11:25.050 --> 11:30.020 You're going to make have an idea in your head of what it's going to look like as well. 11:30.420 --> 11:34.000 And now pause the video and give that a go. 11:37.020 --> 11:38.500 Okay guys welcome back. 11:38.610 --> 11:42.370 Let's go create a flowering bush over in blender. 11:43.300 --> 11:49.880 Okay so I've hopped straight on over into my fluffy bunny and I'm going to create a new layer here. 11:49.900 --> 11:51.840 I'm going to create my bush on. 11:51.970 --> 11:58.480 So let's go ahead and add the sapling and it looks like my cursor was just a little bit away and I'm 11:58.480 --> 12:01.220 just gonna move the lock camera off. 12:01.330 --> 12:04.410 Now I've got just about eight minutes to make this in this video. 12:04.410 --> 12:06.240 So wish me luck. 12:06.250 --> 12:10.690 I'm going to add a level to it and make it a much smaller tree. 12:10.780 --> 12:12.390 About one in height. 12:12.460 --> 12:13.620 Perfect. 12:13.860 --> 12:14.230 Right. 12:14.230 --> 12:15.570 Or in fact it's going to be a Bush. 12:15.580 --> 12:18.890 So let's go and do some branch growth. 12:18.890 --> 12:21.220 Let's yeah the first one one. 12:21.270 --> 12:23.780 The second one point nine. 12:23.800 --> 12:24.410 Excellent. 12:24.410 --> 12:28.300 Now there's too many branches there so let's come back to splits. 12:28.300 --> 12:30.480 Let's reduce that a little. 12:31.350 --> 12:32.220 That's good. 12:32.220 --> 12:35.730 Base size this drop it down just a little. 12:36.430 --> 12:38.130 So it's nice and spread out. 12:38.150 --> 12:41.870 That is looking pretty good. 12:41.930 --> 12:42.730 Okay. 12:42.830 --> 12:46.250 So there's lots of different ways you can go about doing this. 12:46.250 --> 12:51.050 I don't want to make it too complicated and that's probably going to be complicated enough actually 12:51.050 --> 12:53.090 so I'm going to stick with that. 12:53.150 --> 12:57.210 I'm going to shorten the arm length just a little. 12:57.210 --> 12:58.940 Let's go to branch growth. 12:58.940 --> 13:00.520 Let's bring that one down. 13:00.530 --> 13:02.620 And this one up slightly. 13:03.440 --> 13:04.400 Excellent. 13:04.410 --> 13:05.870 So now we've got vose there. 13:05.870 --> 13:09.630 I'm going to keep that as my base because I'm quite happy with that. 13:09.800 --> 13:12.890 So let's go ahead and convert that so that's good. 13:12.890 --> 13:17.860 Find it in here we've got our tree under a rename that bush to be consistent. 13:17.960 --> 13:21.590 And I'm going to convert that to a mesh object. 13:21.590 --> 13:22.210 Brilliant. 13:22.340 --> 13:24.800 I'm going to give that mesh object to material. 13:24.800 --> 13:33.570 I'm going to call it Bach and I'm going to set that Bach colour just to if diff use so dark brown so 13:33.590 --> 13:34.580 stands out. 13:34.730 --> 13:38.810 Okay we need to go ahead and create our flower and our leaf. 13:38.810 --> 13:41.980 Now I'm going to create those on another layer. 13:42.200 --> 13:47.670 So first of all let's create the leaf so I'm going to do that as a very basic leaf. 13:47.720 --> 13:55.160 I'm going to get myself a plane here and I'm going to subdivide it a couple of times so I got some geometry 13:55.160 --> 13:56.390 to work with. 13:56.600 --> 13:58.000 Now they're subdivided it. 13:58.010 --> 14:00.760 I'm going to make sure I'm in proportional editing mode. 14:01.040 --> 14:09.200 It's you're going to start grabbing bits and pulling them about to try and create a general leaf shape 14:10.100 --> 14:11.680 give or take. 14:11.690 --> 14:14.910 Hey there's there is Travis way. 14:15.290 --> 14:16.530 Okay. 14:16.730 --> 14:17.660 There we go. 14:18.210 --> 14:19.810 So in point happy with that. 14:19.810 --> 14:21.300 That rough shape. 14:21.350 --> 14:27.250 I'm just going to twist the leaf ever so slightly to give it a bit more of a dynamic feel. 14:27.260 --> 14:27.890 There we go. 14:27.890 --> 14:29.660 So we've got a leaf there. 14:29.690 --> 14:30.140 Perfect. 14:30.140 --> 14:35.930 A final thing I'm going to do on here's a primer add a subsurface division modifier just to smooth the 14:35.930 --> 14:37.160 leaf out. 14:37.280 --> 14:40.850 And I'm going to place the origin on the end of the leaf. 14:40.880 --> 14:47.000 Otherwise it will stick in the middle of our branches when we try and put it on origins of 3-d cursor. 14:47.000 --> 14:47.480 Perfect. 14:47.480 --> 14:51.450 So that's that one done is a huge leaf but we can deal with that in a bit. 14:51.470 --> 15:00.470 Now we need to bring in enough flour so let's add a mesh image as planes go find a flower now which 15:00.470 --> 15:01.370 one shall I pick. 15:01.400 --> 15:03.860 I am going to pick. 15:04.070 --> 15:05.210 I'm going to pick this blue one. 15:05.210 --> 15:10.730 I do like it's and I'm going to use the alpha channel because I've set up that already diffused and 15:10.730 --> 15:13.010 transparent import. 15:13.160 --> 15:14.500 Excellent. 15:14.540 --> 15:19.090 Let's just focus on that particular. 15:19.100 --> 15:20.040 There we go. 15:20.060 --> 15:24.800 Let's go into edit mode and subdivide that twice. 15:25.010 --> 15:29.780 And that's going to give us some extra geometry on that plane which should allow us to just pull this 15:29.780 --> 15:30.470 down. 15:30.740 --> 15:36.460 With proportional editing again turned on and make ourselves a bit more of a 3-d flower. 15:36.650 --> 15:38.580 Now on it's a have a trumpet that's too big. 15:38.600 --> 15:40.010 That's perfect. 15:40.010 --> 15:46.850 And finally under the move 3D cursor to select it will shift an S and then I'm going to hop into object 15:46.850 --> 15:49.550 mode and set the origin to the 3D cursor. 15:49.730 --> 15:52.530 So again the flowers are mounted on the right points. 15:52.670 --> 15:57.990 Now we've got all that we just need to assign ourselves our virtex groups. 15:58.010 --> 16:02.770 So let's hop into edit mode on this Bush and the object a tour over here. 16:02.770 --> 16:11.030 This add a vertex group called flowers and hop into edit mode with the Bush selected. 16:11.030 --> 16:16.650 I'm going to make sure that I've not got any duplicate vertices going on there by removing doubles. 16:16.700 --> 16:16.970 Yes. 16:16.980 --> 16:20.380 Fifty one of them were removed some glad I gave it a go. 16:20.540 --> 16:25.400 And I want flowers to basically appear on the end of all of these. 16:25.400 --> 16:27.790 Now it looks like I've picked quite a few. 16:27.800 --> 16:32.780 Of course it doesn't need to be every single one but me being me are I'm going to pick every single 16:32.780 --> 16:33.160 one. 16:33.280 --> 16:35.840 Anyway that looks good. 16:36.070 --> 16:39.890 Add Virts group called flowers. 16:39.950 --> 16:41.360 I'm sure I did that a moment ago. 16:41.360 --> 16:44.660 I'm just going to assign those to them. 16:44.670 --> 16:47.960 Right we're going to lock that group so I can't muck around with it. 16:47.960 --> 16:53.630 We'll going to add one called leaves and that's basically going to be the rest of our model with the 16:53.630 --> 16:55.490 flowers D selected. 16:55.700 --> 16:56.840 Perfect. 16:56.840 --> 17:03.010 And now let's go to the leaves click a sign and not lock it just yet. 17:03.020 --> 17:07.460 I'm going to go into a weight paint mode and just remove. 17:07.490 --> 17:10.610 We've got everything painted red there above the tips. 17:10.730 --> 17:17.180 I'm just going to go in and scroll up here go to subtract and remove it from the very bottom because 17:17.180 --> 17:20.690 I do not want leaves coming out of the bottom of the plant. 17:20.690 --> 17:21.110 There we go. 17:21.110 --> 17:23.260 That should be good. 17:23.390 --> 17:24.850 I'm going to lock it. 17:24.920 --> 17:29.670 Let's go into the particle effects and make sure that we are on the Bush we are. 17:29.810 --> 17:32.510 I'm going to add a Flowers. 17:32.510 --> 17:38.480 First of all Ann I'm going to add leaves as well. 17:38.540 --> 17:41.320 So flowers is going to be a hair type. 17:41.330 --> 17:45.680 And it's going to come from a scroll down here. 17:45.680 --> 17:49.630 Density the flower sections all come from the ends. 17:49.670 --> 17:59.260 I'm going to only have what 50 50 flowers coming on there will set the object to the blue flower. 17:59.600 --> 18:00.620 Excellent. 18:00.620 --> 18:02.860 Now I could play about with rotations but I don't feel I. 18:03.050 --> 18:03.770 Time to do that. 18:03.770 --> 18:06.000 I'm going to leave it as it is for the moment. 18:06.140 --> 18:11.660 And then on here on the leaves again it's a tight pair. 18:11.690 --> 18:14.860 Object is going to be our. 18:15.110 --> 18:16.320 Or did a name it is. 18:16.320 --> 18:18.820 It's probably still plain. 18:20.460 --> 18:23.180 I can't score down there we go plain yet. 18:23.220 --> 18:28.380 Those are the leaves are going to have to make them a little bit smaller or ashie that's worked out 18:28.380 --> 18:29.430 quite well. 18:29.430 --> 18:34.950 Now they're a bit too uniform across them actually going to turn on rendered mode to see what happens 18:34.950 --> 18:38.920 and they've not got a material assigned to them so let's go assign the material. 18:39.090 --> 18:40.900 Of course you can probably guess what I'm going to do. 18:40.900 --> 18:43.000 I'm going to assign it a green. 18:43.110 --> 18:45.630 That's a little bit darker. 18:45.810 --> 18:46.830 And there we go. 18:47.010 --> 18:49.670 And I think all we need to do to this. 18:49.670 --> 18:51.640 Have we got any children assigned. 18:51.660 --> 18:54.950 Let's go back to the bush scroll down here. 18:54.960 --> 18:59.160 No we haven't got any children assigned us so we can't apply any randomness. 18:59.220 --> 19:02.410 So I'm going to drop this down to about 200. 19:02.760 --> 19:10.320 Well outlook's much better straightaway than a proper people children on and change the randomness of 19:10.320 --> 19:12.340 the end points. 19:12.450 --> 19:14.860 Twist and round ever so slightly. 19:14.910 --> 19:16.920 We don't want to do that. 19:17.340 --> 19:18.300 That's looking pretty good. 19:18.300 --> 19:23.870 Let's see how that looks in context by switching on the ground plane as well. 19:23.880 --> 19:29.610 So in layers layer management can't see to do grass. 19:29.700 --> 19:31.350 That's the other one. 19:31.350 --> 19:32.640 There we go. 19:32.640 --> 19:35.410 So that's starting to look pretty good. 19:35.460 --> 19:39.390 Let's render that out there that looks okay. 19:39.420 --> 19:45.470 I could certainly work on it a bit longer to make it a bit neater but that's a good start. 19:45.630 --> 19:46.980 How did you guys get on. 19:47.010 --> 19:50.140 I'd love to see what foliage you came up with. 19:50.160 --> 19:52.460 Please share yours in the discussion. 19:52.470 --> 19:58.040 Even if you make a couple different varieties and I will see you guys in the next lecture.
