Blender 2.80 Tutorial: How To Add Bones To An Object.

How to add posable bones/armature to a mesh or body in Blender 2.8.

Skeletal animation is a technique in computer animation in which a character (or other articulated object) is represented in two parts: a surface representation used to draw the character (called skin or mesh) and a hierarchical set of interconnected bones (called the skeleton or rig) used to animate (pose and keyframe) the mesh. While this technique is often used to animate humans or more generally for organic modeling, it only serves to make the animation process more intuitive, and the same technique can be used to control the deformation of any object—such as a door, a spoon, a building, or a galaxy. When the animated object is more general than, for example, a humanoid character, the set of bones may not be hierarchical or interconnected, but it just represents a higher level description of the motion of the part of mesh or skin it is influencing.
The technique was introduced in 1988 by Nadia Magnenat Thalmann, Richard Laperrière, and Daniel Thalmann. This technique is used in virtually all animation systems where simplified user interfaces allows animators to control often complex algorithms and a huge amount of geometry; most notably through inverse kinematics and other "goal-oriented" techniques. In principle, however, the intention of the technique is never to imitate real anatomy or physical processes, but only to control the deformation of the mesh data.
This technique is used by constructing a series of 'bones,' sometimes referred to as rigging. Each bone has a three-dimensional transformation from the default bind pose (which includes its position, scale and orientation), and an optional parent bone. The bones therefore form a hierarchy. The full transform of a child node is the product of its parent transform and its own transform. So moving a thigh-bone will move the lower leg too. As the character is animated, the bones change their transformation over time, under the influence of some animation controller. A rig is generally composed of both forward kinematics and inverse kinematics parts that may interact with each other. Skeletal animation is referring to the forward kinematics part of the rig, where a complete set of bone configurations identifies a unique pose.
Each bone in the skeleton is associated with some portion of the character's visual representation in a process called skinning. In the most common case of a polygonal mesh character, the bone is associated with a group of vertices; for example, in a model of a human being, the 'thigh' bone would be associated with the vertices making up the polygons in the model's thigh. Portions of the character's skin can normally be associated with multiple bones, each one having a scaling factors called vertex weights, or blend weights. The movement of skin near the joints of two bones, can therefore be influenced by both bones. In most state-of-the-art graphical engines, the skinning process is done on the GPU thanks to a shader program.
For a polygonal mesh, each vertex can have a blend weight for each bone. To calculate the final position of the vertex, a transformation matrix is created for each bone which, when applied to the vertex, first puts the vertex in bone space then puts it back into mesh space. After applying a matrix to the vertex, it is scaled by its corresponding weight. This algorithm is called matrix palette skinning, because the set of bone transformations (stored as transform matrices) form a palette for the skin vertex to choose from.

"A little chap running" I LOVE THAT SO MUCH

[basspig]

There are so many things that are hidden in Blender that if you don't have someone showing you where and how to find the tools, there's no clue how to begin. This tutorial was helpful in uncovering some of the hidden tools.

[alexandersergal]

this has been the most helpful tutorial for blender ive seen so far. Because you dont act like you have five minutes to get to work and you have a fifteen minute drive ahead.

[colli_cf]

For those who came here to fix any issues about the mesh (like shrinking)

try to turn on the "preserve volume" in the armature modifier

[brain_apostrophe_t]

HEY! If you're like me and you were wondering how he grabbed all the bones at once for the parenting section, you can grab all your bones and hit Control J to join them. It seems obvious in retrospect but it worked a charm.

[atrixentertainmendreply]

I have never seen a tutorial made with so much enthusiasm like this one, make my day 👍

[pizzi_]

Thank you, this helped so much!

Btw if someone's rig doesnt work, make sure the armature is the parent of the sphere, and not the sphere is the parent of the armature.

[MrShroombot]

Great tutorial. Easy to follow and a pace that beginners can follow as a great guide. Thank you!

[quentingartner]

THX thats the best blender tutoriell liv watcht until now!

[QayLikeKay]

If the armature menu does not appear, make sure you're in object mode

[FairButNotReally]

Oh my god that was so easy, Yet there's hardly any (non-video) documentation.

I listen to music while working so I like reading the documentation.

Thank you kind stranger! First day on Blender so I needed the help.

[samminniota]

It has helped me Chipper. Thank you, friend.

[ebo]

A thousand thanks for the no bs vid, no intro no asking to like and sub, and all your buttons presses are shown, please keep being you. For not asking for a sub you get a sub.

[DJRussellBrian]

I watched about 10 videos trying to figure this out and I just want to say thank you for making this video. You explained how to add bones very well and I will be subscribing to your channel for more educational videos!

[chrisbarnes]

I'm just getting into blender, as in I've been working with it for about two weeks. This simple tutorial helped me out. Cheers

[gavinlopez]

Thank you for watching, cheers! I loved that

[Crysal]

Surprisingly good tutorial, I've basically never used blender before, but I got bones into a model that I then could export into the software I needed.

[Hopeofhell]

As someone trying to add bones to a model just for VRC with zero understanding of Blender, Super helpful and straight to the point still to this day ♥

[randomrsifO_O]

Thanks Mate, btw I swear I was falling asleep to this, your voice is so calming!

[nosohoentertainment]

Used this tutorial to anchor a door to its hinges, thanks for the help.
