How to Use a Unity VFX Effect in Three.js?

Hi everyone,

I am currently working on a project where I need to use a visual effect (VFX) that was created in Unity within a Three.js application. I am looking for guidance on the best approach to achieve this.

Here are a few specific questions I have:

  1. What file format should I export the VFX from Unity to ensure compatibility with Three.js?
  2. Are there any specific tools or libraries that can facilitate the conversion or import process?
  3. Can someone provide a step-by-step guide or resources that detail the process of integrating Unity VFX into Three.js?

Any help or insights from those who have tackled similar challenges would be greatly appreciated!

Thanks in advance.

AFAIK, it is not possible to export a VFX Graph into a format that can be imported elsewhere. It is a proprietary technique that works just in Unity.


That being said, needle tools may be able to capacitate a custom shader exporter of this nature out into an r3f component but you’d have to read into it as I’m not 100% sure…

Actually, I am developing an open-world game and want to add effects like wind effects when a vehicle flies or a dinosaur flaps its wings or glides, nitro effects for the vehicle, and adding VFX effects to sword animations for the character. What is the quickest way to achieve these?

In unity or in 3js? If 3js, I think you should ideally create a new question related to what you’re trying to achieve in three, some reference images to the effects and a live code example as to what you’re already trying…

Yes, I’m working on adding visual effects to my game made with Three.js. However, you are right; I should probably prepare a new question with more detailed information, including reference images and a live code example to better illustrate what I’m trying to achieve.

Sounds like you need a particle system.

This one has a few things in its markeplace that could be a good starting point. (Haven’t tried it)
three-nebula is another one that could be useful.


+1 there’s also libs such as trail renderer that could come in handy…

Thank you for the helpful suggestions! I’ll explore the particle systems and trail renderers you recommended to improve my game.
