My blender stoped to make subdivisions When I press  + &lt;2>, the program seems to work, but when I go to the sculpture tab, it just doesn't work, when I go to the edit mode that's what I see.



At some point I disabled subdivision, and I don't know how I did it or how to get back to normal
You need to apply the subdivision surface modifier in order to actually get those extra vertices. As of now, you can only move and sculpt those 8 vertices.
