@bitinn Man, that's so nice to see. First game I worked on. I implemented the lighting system, material system, and effects system, fresh off of a Global Illumination PhD from CMU. Plus a few other things. Even the lot imposterisation system for the neighbourhood launch screen was quite advanced for the time.
I thought in particular the guy who owned the animation system was on the top of his game, but sadly he left the games industry a few years afterwards.
A bit of both if I recall. The CPU-generated lightmap would be updated with broad-scale pseudo-radiosity effects, but we also had the classic (at the time) most-influential-point-lights thing on the GPU, basically via 2-band SH. (I think! It was a long time ago.)
