Can't see particles system with transparent canvas

Hello! I’m currently trying to implement an overlay effect with Babylon. In order to do it, I set the scene clearColor transparent : scene.clearColor = new Color4(0,0,0,0)

Everything seems to work fine except for the particles system. I tried each blendMode and they simply appear on top of the other objects in my scene. I can’t see the particles when there is nothing behind.

Is there a way to fix this issue?

Ok, so I found the solution and in order to see particles in a transparent canvas, you have to do that :

particleSystem.renderingGroupId = 1;

I hope that it will help someone!
