default shaders

I'm having problems with the shaders that are included in the gamestudio directory; they work fine in the included demo, but don't seem to work when I add them to my game. The specific shader I am having a problem with is specbump.fx.

are you applying the shader to level geometry or models?

I am having issues when this particular shader is applied to level geometry in terms of one side not being rendered

Oh sorry, they are being applied to models. I am using the normal maps and everything; I've done this tons of times with other shaders and have even edited some myself for simple things so it's not like some kind of newbie thing; I just wanted to use the default shaders. Interestingly enough, the other default shaders work great, it's just the normal mapping ones that don't seem to work outside of the demo.

So in other words, nothing?

And what is not working exactly? You should also post your code
