Getting identical results is actually shockingly complicated. There's a _ton_ of computation in the fixed-function pipeline, and you'll have to duplicate all of it. As the number of lights increases, the shader complexity increases as well. Fully expect the need to dive deep if you're going to have a complicated pipeline that behaves comparably with Fixed Function and Shaders with non-trivial GL state. -- Christopher Wright [email protected]
