This Geometry Nodes setup generates fully procedural, animated thunderclouds. Users can append the cloud object to a scene and adjust parameters through the modifier panel to control dimensions, shapes, and overall scale. A randomization option generates a unique cloud structure with each click.

The system includes procedural lightning featuring internal light points that illuminate the surrounding cloud volume. The entire setup is animated automatically, requiring no manual keyframes, and scales from single distinct clouds to scene-wide atmospheric coverage.
