We introduce SwitchLight, an architecture based on Cook-Torrance rendering physics, enhanced with a selfsupervised pre-training framework. This co-designed approach significantly outperforms previous models. Our future plans include scaling the current model beyond images to encompass video and 3D data. We hope our proposal serve as a new foundational model for relighting tasks.
