I have a cube-based world like Minecraft and I'm wondering if there's a way to construct a cube with fewer than 24 vertices so I can reduce memory usage.

It doesn't seem possible to me for 2 reasons: the normals wouldn't come out right and per-face textures wouldn't work.

Is this the case or am I wrong? Maybe there's some fancy new DX11 tech that can help?

Edit: Just to clarify, I have 2 requirements: I need surface normals for each cube face in order to do proper lighting and I need a way to address a different indexes in a texture array for each cube face
