That worked perfectly. As I saw the word crease angle I immediately thought
about the same notion in VRML. Interpolation between normals is only done if
the angle is smaller than this value, so if it is too small, the drastic change
in direction of the normals at the edges and the vertices is too big, giving all
those nasty shadows. To check if it was really that, I put the crease angle back
to zero, but to no avail, I have to recreate the cube. Anyway this helps me a
lot, thanks.
