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