About this asset
Koi's Black Hole Generator is a customizable black hole VFX authoring tool for Unity URP.
Create a black hole that fits your scene using real-time visual controls, built-in presets and Simple or Advanced editing modes. Adjust the accretion disk, HDR colors, photon ring, gravitational lensing, scale and motion while previewing the result directly in Unity.
The optional Koi Space Optics scene-distortion system can bend visible pixels from the destination scene, including the skybox and scene objects. Installation is controlled by the project owner and can be added or removed when needed.
Save reusable presets, create your own variations, and export the current design as a runtime Prefab in a single .unitypackage with the required dependencies.
Export also creates and verifies an independent preset backup before packaging, helping protect your current design if an export fails.
A runtime API is included for controlling supported properties from your own scripts.
The package includes Demo scenes, built-in presets and a self-contained multilingual HTML manual with 15 selectable languages, search and printing support.

- Actual GPU cost depends on screen coverage, resolution and overlapping effects
- No specific frame-rate guarantee is made
Camera and distortion limitations
- Orthographic, XR and Overlay cameras use a body-only fallback
- Screen-space distortion cannot reconstruct off-screen or hidden surfaces
- Late overlay UI is not refracted
- HDR, Bloom, tonemapping, render scale and other post-processing settings can change the final visual result
- Demo Bloom and ACES settings are not forced onto exported runtime projects
Runtime export
