Blender game normal mapping I have a ground tile for which I use a normal map, it reacts good when facing light, but looking in the Sun lamp direction kills the lightning. I'm using nodes, have a look at the pictures.
Can somebody tell me what's wrong with my setup ?
(connecting the texture normal output straight to the material gives the same result)
You could try advanced material node. This can be  found under the input menu. Otherwise you could just add the normal map in the texture panel and enable normal map at the bottom.
