How to build this in Blender:
1) Add a cube if you don't already have one
2) Go to edit mode (TAB)
3) Mesh -> Edges -> Edge Split (CTRL+E)
4) Triangulate faces (CTRL+T)
You can now see in the top info row: Verts:24/24 | Edges:30/30 | Faces:12/12 | Tris: 12 and the model should be like you need in the tutorial.
I think the tutorial might have served more as an introduction to concept of vertices, edges, faces, normals in this case
Hey there this actually worked! Thanks for that. Everything works fine. One important thing to mention here is, one should first apply textures and triangulate and edgesplit later. Otherwise UVs seem to screw up.
