Can't see part of the mesh in object mode I'm following the book Introduction to Character Animation in Blender. I stopped a long time ago and now I'm starting again so I'm confused about many things. I know you unhide with Alt+H but that doesn't work. I've read a few threads I found on Google but I could not find the solution. I'm linking to my file so you can look at it.

EDIT: I also can't see the texture I added to the head material. I thought it was because the path to the image had changed, but no. In an earlier version of the file I can fix it by reloading the image (because the path changed), but not in this one. Last thing, any time I hit render it crashes.
Turn off Armature modifier's ... "Bind to" > Vertex Group.


Note : It also starts to render with no issue.
