Armature Modifier in Blender<br /><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 Works<br /><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 Modifier<br /><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 />🔹 Example<br /><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.
