Question

I did it well, but I cannot understand how Vertex Groups was connected with bones. Through similar names or through just similar position?

Hi Alex,

The Vertex Groups need to have the exact same names as the corresponding Bones.

You assign vertices to the vertex group so that the bones can have influence on them. So if you have a cube with 20 vertices and you assign 5 vertices to the vertex group, the bone will move those 5 vertices but the other 15 wont do anything because they are not assigned.

When an armature modifier is put on a mesh there are 2 options on the modifier. Vertex groups and envelopes. Vertex groups is the default. When you move a bone in pose mode any objects(usually mesh) with an armature modifier with that armature as it's target will compare that bones name to the list of vertex groups. Oh and it is case sensitive so too and Top are different. Then it calculates how much to deform the vertices assign to that group based on a normalize weight value. Vertices can be assigned to multiple vertex groups and be influenced by multiple bones. Blender needs a number between 0 and 1. If it's higher blender will adjust the weights to be a total of 1. This is called normalizing.
