Lighting Technology of The Last of Us Part II

Since the majority of the world of The Last of Us Part II has overcast lighting conditions, ambient lighting was a crucial component of our rendering system. Developing a game that is mainly ambient lit is already a challenge on its own, but we also had to deal with limited amount of processing power and memory on our target platform, Playstation 4. In this abstract we will mainly focus on improvements of our baked ambient lighting system that enabled us to produce convincing and consistent lighting results while maintaining our target of 30 fps and remaining within our limited memory budget.
