This command is needed in order for me to set the lighting for the Per Pixel Lighting shader I'm trying to get working in Dark GDK, however, this command is not even available...why?

Can't you just use dbSetEffectConstantVector?

Those aren't the same commands. The LightPos constant is actually an array of 8 lights, and you have to use the dbSetEffectConstantVectorElement command in order to access each light in the array that is declared in the shader. The documentation tells you to use this command, but it does not exist in the GDK version.

Have you tried to manually add the function definition to the header file?
Sometimes that can be missing...

Well I added dbSetEffectConstantVectorElement() to the header file and it seemed to recognize it as a valid command, but then I got a runtime error that said I had to use dbGetObjectEffect(), which apparently returns an int...I then did the code to try to get the lights to work and they still don't...I'm going to go to tech support about this.

I do not completely understand what you explain.
Maybe a parameter has the wrong kind or there is some mistake in the function definition that you added.
I don't have the DarkShader help files at hand, but you could post the related information, as well as the function definition that you used. The same about that error and even some source code.
I don't think that people can help you with the current information, unless they have solved this before, that is.
