I feel like this should be really easy but I'm not seeing it. I have a character that part of the head is hidden. When I click Edit Mesh then I can see all of the vertices and faces, including of the hidden portion of the mesh. How do I select all of the head mesh at once so I can click show to make the entire head visible. So far I only see how to select vertices, faces, and elements. I thought it would be in the elements area but when I click on the head there then the whole body is selected.
