IES Master Studio is an Unreal Engine 5 Editor tool for creating custom IES photometric light profiles directly inside the editor.

• The plugin provides a procedural, layer-based system to design complex light distributions using beam shaping, multi-peak control, asymmetry, and procedural noise. You can preview the result instantly through analytic 2D views, an interactive 3D distribution preview, and a real-time scene using a transient Texture Light Profile.

This tool is designed for lighting artists, technical artists, and environment artists who need full artistic control over photometric profiles without leaving Unreal Editor.

Editor-only plugin. No runtime dependency.
