Abstract
Designing effective lighting is an iterative and often time-consuming process. This work contributes to automatic lighting design research by presenting a render-engine-agnostic optimization routine: gradient descent on RGB multipliers of one-light-at-a-time (OLAT) basis images. We propose several objective functions to accomplish lighting tasks and show that our method is capable of quickly and effectively exploring different lighting styles using either text prompts or reference images.
