I wanted to make this particle effect, I first used the Cylinder Emitter and noise texture from the documentation. I wanted to change the emitter to look like Box. But I don’t understand the code.I think my goal is accomplished by modifying the circular emitter to emit particles from all four sides like a square. Can someone teach me :slight_smile:

I think it might need to be changed to “articleSystem.createBoxEmitter” but I don’t know what data to put in () 。。。。

For the simplicity, you can:

  1. Make the Playground with your code with particles.
  2. Open the Inspector and choose Particle systems.

Hello, I would like to ask how long will this ID be kept?

Forever :slight_smile:
Babylon approach to PG and all snippets is that all URL addresses are immutable and will live forever.

I would also like to ask how to make the particles not disappear, they will always be there
