[Solved] Why no lighting?

Recommended Posts

Hi,

I've tried everything. And can't find out why i dont get to lit my vertices.
I do this in C++ and it works, but not in C#. why?

I also tried set VertexFormat to different formats, but still just a black sphere (or mesh).
Tried almost everything, i wonder if there's something wrong with the transformations.
But the ambient values should work anyway, so i just dont seem why it would be wrong.

Sorry for pasting long code, but i just have to do this (its not too long anyway, just a simple app).
