3d workspace not working

Hi! I am having trouble getting my workspace to properly display in 3D. It was working fine yesteray. I tried resetting my workspace and even reinstalling photoshop, but when it still won't display the way it should. And if I click any of the camera controls or light controls or material controls, it splits the object into 4 fragments. 

The attached image is supposed to be a pyramid. All the 3d view options are checked to show in the view menu. what happened??

tearing my hair out over here.
