Koi's Wormhole Generator

Koi's Wormhole Generator is a customizable real-time wormhole VFX tool for Unity 6 URP.

Create and customize wormholes directly inside Unity with real-time preview. Adjust passage size and length, HDR colors, ribbons, particles, animation, entrance distortion, interior space-time deformation, chromatic effects and more.

The optical effect provides continuous screen-space deformation from the entrance through the interior passage, allowing visible scene objects and spacecraft to bend, stretch and drift during an actual fly-through instead of only showing distortion at the portal surface.

The included FLY THROUGH demo automatically sends a sample ship through the wormhole with a follow camera. You can also assign your own ship Prefab to preview the same traversal with its existing visual effects.

Choose from built-in presets, save your own designs, and export the finished wormhole as a single runtime .unitypackage for use in another URP project.

The package also includes a runtime-ready Prefab, Runtime API, Koi Space Optics scene distortion, High / Medium / Mobile quality modes, automatic export backups, demo scenes, and a 15-language PDF manual.

Suitable for sci-fi games, interstellar travel, dimensional gateways, cinematic sequences and space environments.

Note: Wormhole traversal is a visual effect. Teleportation, gameplay logic and physics interaction are not included. Spaceship and exhaust effects shown in promotional footage are for demonstration purposes and are not included in this package.
