>The Build effect works on Meshes and causes the faces of the Object
  to appear, one after the other, over time. If the Material of the Mesh
  is a Halo Material, rather than a standard one, then the vertices of the
  Mesh, not the faces, appear one after another.</P

  be re-sorted as a function of their value (Z co-ordinate) in the

    do much because the Z-axis is orthogonal to the plane. You must rotate
    it in EditMode to have some numerical difference between the co-ordinates
    of the faces, in order to be able to reorder them.</P
