Abstract:
This talk discusses in detail the area lights technique used in Cyberpunk 2077. We outline the limitations and challenges we had, and then present our solution. Particularly, we describe our 100% analytical capsule lights, our spot-capsule solution, and our capsule light shadow technique. We then discuss our artistic pipeline, our performance results, and limitations.
