VRChat Black Hole Physics World Asset

The Black Hole Physics Asset is now available for VRChat worlds!

This customizable UdonSharp system creates a powerful suction zone that can pull physics objects toward a central point, send them spiraling into orbit, and optionally consume and respawn them.

It can also be configured to pull players, making it useful for traps, hazards, minigames, supernatural effects, space environments, and interactive world events.

What It Can Do

Pull Rigidbody objects toward the black hole

Increase the pull strength as objects get closer

Add an optional swirling or orbital motion

Limit object speed to keep the physics controlled

Ignore objects currently held by players

Filter affected objects using Unity layers

Optionally pull the local player

Configure horizontal-only or full 3D player movement

Add player orbit, vertical lift, and distance-based acceleration

Consume objects that reach the event horizon

Automatically restore consumed objects after a configurable delay

Respawn synchronized objects using VRCObjectSync

Optionally respawn players who reach the center

Fully Customizable

Nearly every part of the effect can be adjusted directly from the Unity Inspector.

Control settings such as:

Pull strength

Maximum speed

Suction falloff

Swirl strength

Event-horizon distance

Object respawn delay

Player acceleration and deceleration

Player pull speed

Player lift and vertical movement

Affected object layers

Maximum tracked objects

You can create anything from a gentle gravitational field to an aggressive black hole that rapidly pulls nearby objects and players into its center.

Object Consumption and Respawning

Objects that reach the center can either remain active or be temporarily consumed.

When object consumption is enabled, the system can:

Hide the consumed object

Wait for a configurable delay

Respawn objects using VRCObjectSync

Return unsynchronized objects to their original position

Use an optional custom respawn location

This makes the system reusable without permanently removing your world’s interactive objects.

Performance Options

The asset includes configurable performance features designed to avoid unnecessary background processing.

Trigger-based object tracking

Configurable maximum tracked-object count

Initial overlap scanning for objects already inside the trigger

Separate initial detection for the local player

Non-allocating overlap checks

Delayed respawn processing

Great For

Space and science-fiction worlds

Magical vortexes

Environmental hazards

Traps and obstacle courses

Boss encounters

Physics demonstrations

Minigames

Destruction events

Interactive world effects

The package includes the UdonSharp black hole system and a ready-to-configure prefab, allowing you to quickly place it in your world and customize the effect for your project.
