BRef is a tool for managing reference images within the 3D viewport. It allows users to place floating overlay images that can be repositioned, scaled, and organized into layers directly on screen. Additionally, the add-on automates the setup of orthographic scene references by creating and positioning Blender Empties for front, back, side, top, and bottom views. Images are managed through a dedicated sidebar panel, which includes controls for opacity, aspect ratio locking, and visibility.
