Model won't follow its armature in pose mode I've set up a rig and built it around my model, and I've linked it to my model but when I rotate the bones in pose mode, the character doesn't move with them. 

My rig is the human meta rig that comes with rigify. I've seen tons of videos of it working. Why isn't it working on mine?

My character was made by creating different body parts and joining them together into the same object, then a texture was added by unwrapping them in texture mode.
try following these steps

after joining all the separate parts and the body mesh together, you should parent the body mesh to the armature by ( in object mode )


selecting the mesh then the armature and pressing Ctrl P
select Armature Deform >> With Automatic Weights
select only the mesh and go to Modifiers
deselect Bone Envelopes in the Armature Modifier





press Tab to enter Edit Mode and navigate to Vertex Groups
ensure only necessary vertices belong to each Vertex Group





press Tab to enter Object Mode
select the armature and press Ctrl Tab to enter Pose Mode
select a bone and move by pressing G or rotate by pressing R


hope this helps!
