Armature Modifier in Blender
The Armature Modifier is what actually connects a 3D mesh (your model) to an Armature (skeleton) so that the bones can deform the mesh during animation.
Without this modifier, the armature won’t affect the mesh—it would just be a skeleton floating nearby.
🔑 How It Works
You create an Armature (skeleton).
You create a Mesh (character or object).
You add an Armature Modifier to the mesh.
In the modifier, you assign which armature should control it.
The mesh deforms according to the armature’s bones + weight painting.
🔹 Main Options in the Armature Modifier
Object → The armature that controls the mesh.
Vertex Groups → Uses weight painting to decide which parts of the mesh each bone influences.
Preserve Volume → Helps maintain volume when bending (e.g., elbows don’t collapse too much).
Multi Modifier → Lets multiple armatures influence the same mesh.
🔹 Example
You model a character.
You create an armature with bones (spine, arms, legs).
You add an Armature Modifier to the character mesh.
Now when you rotate a bone in Pose Mode, the mesh bends along with it.
