Add On The Fly is a Blender addon that reaches the main data of the active object and lets you manage its properties directly. It covers cameras, lights, meshes, curves, empties, text and render settings, gathering those controls into a single addon.
For lights, it can toggle a light on or off while keeping it visible in the 3D viewport, currently with Cycles only, and set the main light parameters through a Modal Light control — with colour via the modal available when using Photographer. It also sets the main camera parameters, handles hair particle setup, manages Scatter5 settings for Scatter 5.2, covers render, and manages selections through the Add on the Fly pie menu.
Add On The Fly is listed for Blender version 5.0 and released under the GPL license, with documentation included and a demo video available. It earns its spot in the Superhive library for pulling active-object data into callable controls.
