object completely disappears in sculpt I have been doing Andrew Price's anvil tutorial repeatedly with quite a few restarts from scratch.  My latest attempt was fine through completion of UV unwrapping.  then I entered sculpt mode and the anvil goes completely invisible.  I deleted the file and restarted, getting very little done before entering sculpt just to see and again the object is completely invisible.  I tried changing matcap and managed to get a dark gray silhouette.  I am linking to my .blend
Havent you entered the edit mode then hid the object and then went back to layout? The object stays hidden in edit mode so does in sculpt but not in layout, you just have to go to layout enter edit mode alt+H to make visible everything and then you can change to sculpt.
