    Some of my own lighting issues

    I have seen a couple of other threads on here lately regarding lighting, so I felt I might chime in with my own lighting issues.

    All my normals are being calculated and applied perfectly fine, so that is not the issue.

    [edit]

    Since no one has replied, and my problem has slightly changed since I initially posted, I am going to edit this post.

    I got a lot of my lighting stuff working, but it seems like my light is moving with the camera, even though I specify a position for the light. I want the light to stay in one place so that it lights a specific room...how would I go about doing this?

    I am not sure, but I think you might have to check if a polygon can see the light. So, if the light is in one room, polygons in the other rooms cant see it and will not be effected by it.

    Is this being done in a shader or fixed-function? Are you able to post any code?

    Are you transforming your normals to world space prior to the lighting?? You will need the inverse transpose world matrix to transform the normals.
