Hello everyone

is it possible to invisible each particle in PCS? I didn’t find anything in the documentation.

I use the following code for do it:

```
var pcs= new BABYLON.PointsCloudSystem("pcs", 1, scene) 
pcs.addPoints(10000);
pcs.buildMeshAsync();
pcs.particles.forEach((particle) => {
    particle.isVisible = false;
});

```

One way I able to do this was setting the entire mesh visibility to 0.

```
engine.runRenderLoop(() => {
    pcs.mesh.visibility = 0;
});

```

I think there is a better way to set the individual particle (for example if you wanted different particles to be different alphas) Perhaps this line in the documentation helps?

- Changes to particle properties can be achieved with the `initParticles()` or `updateParticle(particle)` methods and a call to `setParticles` .

Thanks a lot 🙏, I am going to try it.  
I cannot use `engine.runRenderLoop(() => { pcs.mesh.visibility = 0; });` because I want to use a check box to show and hide the model
