Light Placer

Viewport light placement/editing tool for Isaac Sim.

Installation

1. Add this extension's parent folder as an extension search path: Window > Extensions > ⚙ > Extension Search Paths.
2. Enable Light Placer in the Extensions window.

Usage

1. Hover the viewport and press C to activate Light Placer.
2. Move the mouse over geometry to preview placement.
