LuminaBrush provides an interactive tool for adding illumination effects to images, targeting artists and image editors. It simplifies complex relighting tasks by decomposing the process into two stages, enabling more intuitive control and consistent results.

How It Works

The framework employs a two-stage approach. The first stage converts input images into a "uniformly-lit" appearance, effectively removing existing lighting. The second stage then generates desired illumination effects based on user-provided scribbles, applied to the uniformly-lit image. This decomposition simplifies the learning process by avoiding the need for complex light transport consistency constraints, leading to more stable model behavior.
