Meshes and Armatures: Rigging

How everything is connected, or: why your edited mesh moves weirdly

Summary

This page will give you a short explanation on why 3d objects are moving.

Wait, this is not what I want!

The connection between a mesh and a rig is made via vertex groups. Any number of vertices can be assigned to a group, which is then matched to a rig's bone via name.

These vertices move with the bone "Spine3"

How much every bone influences the vertices is determined by vertex weight, which can be altered in Blender's Weight Paint perspective:

Vertex weights are assigned for every vertex group, and each vertex will move on the basis of the sum of all its weights.

You can see a video of the process here (courtesy of Vesna).
