Model does not move after I put a rig I recently put my first rig to a model with rigify, the problem is that when I go to pose mode some parts of the model do not move as you can see:



Any help?

Thanks
You need to add weight painting to this part of the mesh as well. First click on the mesh (model) then keep holding the shift button and click on the rig then hit ctrl+P then select parent with Automatic weighting, this should fix this.
