Blender: Fast B-Bone Rig (Easy tutorial)

hello guys and welcome to another tutorial today I'm going to be showing you how to make this bendy hose a big in blender to connect free now this is a very useful kind of regular has two control points like you can see here one is a base control and one is an end control and then you have this bone in the middle that's being manipulated by these two it's super easy to do it's one of the easiest rigs you can do forty mount you get out of it like you could do rotation on these little controllers and you can move them around both of them can be rotated like this and effect the middle spine bone and I made a you can make them as high as you want you can see here is another example I made one here where I made it really long so I go to mypos mode here is an example so you you could use this for a lot of things I primarily use these when I do character limbs like release stylized characters so yeah I'm going to show you how to do this it's going to be a quick tutorial very easy I hope you guys like it implemented in your workflow and show me what you make so let's get into a new scene in blender so what I'm going to do is I'll just enable my screencast keys for you guys so you can see what I'm pressing down here okay so I'm just going to go eight just like everything and then X and delete so we just have a nice clean seen here in blunder I'm gonna go shift a and let's go down and add in an armature and so we added in an armature and by default it's gonna make it and a tree he drew one I thinks if you go here to your bone settings and you go to viewport display yeah it should be it octahedral but whenever we're doing these sort of this kind of rake with bendy bones we need to make it be bone so you can see here B bones which stands for bendy bones you can click on that and here we have a bendy bunch so just like when we're working with any sort of mesh or a cube or some primitive object in blender this exact some of the rigs we want to go into an edit mode so you can come up here just like you usually do and you can go into your edit mode just like anything else the only difference is there's no you're not cutting any sort of mesh or adding in vertices anything what you're doing is extruding points and placing in button so what we're gonna do is grab this little nub on the end here and we're gonna go G Z and just bring it down to something like this and then what we're gonna do is with this little nub selected we're gonna go e to extrude and we're gonna hit C just to extrude up and these two bones are connected so if I were to grab this move it you can see they are connected and so I'm going to grab this Giger G Zed and you want to move this as high as the length of the object you want to rig with it so I'm just gonna go something like - is an example maybe even a little bit less tempting here and then I'm gonna go e to extrude one more time and hit Z and just make another little nub now these two little nubs are both connected to this guy here and if they're going to be controlling it but what we want to do is grab this guy at the top and we want to go alt P and we want to clear the parent and we're going to go alt P and we want to disconnect the bone so this needs to be its own separate bone okay and but these two will still be connected now what we can do to make things a little bit easier in a viewport if if you go ctrl alt s with this bone selected you can scale it in like so okay you can see what I'm doing is so we can make it a little bit thinner so these control points stent it just looks a bit more visually pleasing to me personally and if you can see if you were to grab this and actually just hit s by itself this would happen that's why we go ctrl alt s whenever we want to mess around up to thickness of our bones okay but at the moment before we add in our constraints you want to make sure we can add some divisions to dissapoint so what we're going to do if this bone selected let's go to our bone properties here go down to the vendee button options and we want to add in some segments because right now if we were to move these around this thing isn't gonna be able to bend because it doesn't have any segments to it so let's come in here come to the segments undo the bendy bones and let's increase the segments now you can make this whatever you want depending on how much geometry have to deform if you have something that's got a lot of detail might suggest maybe something like 32 is usually quite a good number for me so I'm going to just type in 32 and this is all of our bones placed as they should be and that is all good so let's now go into our pose mode and a pose mode we can do I do two things we can animate or we can add constraints and properties to our bones so what we're going to be doing now is adding constraints what I want to do is we want to select this bone here first holding in shift to want to select the bones that it's going to be controlling its going to be affecting this bug there's one is going to be in the hierarchy of our constraints then we're going to go shift ctrl C that's going to open up this tab and we're going to go and give this guy a stretch too so if we grab this control now we go G you can see this guy is stretching along if you grab this guy to bottom it's also stretching along but at the moment there's only one thing that's not quite there yet if we rotate this guy you can see it rotates but if we grab this guy at the top it's not going to rotate so now we're going to do is come over here into our bone properties panel here and we want to come down to this little section here where we see start handle and end handle now one thing I did forget to do but it's not hard to do is just quickly rename these bones so this has got to move this guy at the top selected and over here on our bone property she's prepped at top here and let's call this guy and so it's our end controller grab the guy at the bottom and just call it base and hit enter and you can call this one in the middle something if you wanted to I just call it mid or spying or something so what we're gonna do is have this guy selected because it has two constraint added to it we're going to come here to have bendy bones under up any bones tab if you go down you can see a start handle we want to take the start handle setting here we want to make it absolute and we want to select this bone called base the first one then we're going to grab the second one here at below it and we want to make it absolute as well and over here we're going to come and grab that and the bone so now if we grab this guy and not only can we move it we could also rotate it which gives us a lot more control and this one at the bottom can also do that so this is extremely useful little rig now one little tip I can give you guys because I found this out the hard way because I'm using the blender 2.8 and free alpha something is different so now if you select all your bones once you've moved them around in your viewport you can no longer go alte G alt R and Valdez to put things back into their original place so what you have to do is hit f3 in your number pad and you have to type in clear pose transforms type and clear pose transforms and hit that and everything will go back to where it originally was so that's a little tip for you guys so let's just quickly add something to this it's just something I want to do so let's come into our front view here and now it's important that you go into object mode again so you can add something in and we're gonna go shift a node our measure options I'm going to add in a UV sphere I'm just gonna scale it down something like this captain to edit mode rabb these vertices at the top and this is just a quick little example of how it's useful I'm gonna control are just adding a whole bunch of loop cuts here double click how about of edit mode go control a and just apply it this scale on that so now if I select this rig here holding in ship I don't select cylinder here to capsule and then holding in shift select the rig you can go control P and we'll go down to with automatic weights so now if we grab our rig here and we go into our pose mode and we actually move it around you can see it is actually deforming this mesh and this like I said is a very useful thing you could use this for a worm animation it's more practical for stylized animations it's not something I would use for like a very realistic character but I do use it a lot in some of my work in my characters and it can be using a ton of things I hope you guys found this tutorial useful and if you do make something cool with it put it into your workflow I will not be making this available on the patreon page because it's such a basic thing it's not even worth clogging up my patreon page of this sort of thing so I'm just gonna leave it at this and I hope you guys are able to yeah make something cool of it I'll see you guys for another tutorial coming up real soon later
