I have a strange problem I need some help with… I have a model that when entering into edit mode none of the elements move; vertices, edges, faces, but snapping is turned off and alternating between Local and Global transformation as well as Local, Normal, and Global view modes make no difference. Oddly enough, when I try to move a face the face will collapse all of the vertices into the center. The translate widget will move but the face/vertex/edge stays in the same place.
I am sure it is some setting I have done at the object level. None of the other objects in the scene are affected; this object is the only one without a rig (it does have shape keys but removing them did nothing.) I have appended the mesh to new files with no change and tried all of the (I believe) obvious settings, but I am a total newbie to Blender so there is sure to be an easy answer I am missing.
