Oh, that was really mk_1 on the Irrlicht IRC channel I thought about asking if it is him, but decided against it :P

I guess that you now the problem with stencil shadows and open meshes? I hope that that is the problem causing the strang selfshadowing. The problem can also be seen in the example, though it is far not that visible. I did not check it, but I guess that the mesh is open.
The normalmapping shader supports a glossmap but I did not have one. And I dropped that shader for now anyways.

Yes, I know that my taskbar is crowded and I don´t like it, but the only window I did not really need was SED.
