How would I create a ring of cloud?

Hello. This is my first question and I am very new to UE4. I am trying to create a galaxy for an immersive game environment that is basically made up of “rings” of gas clouds and asteroids like the picture found here . Does anyone have any idea how I could create an emitter in the shape of a ring and emit a cloud (not worried so much about the material because I have that worked out) as well as other particles to mimic what’s happening in the image? Any help would be great. I’ve watched a lot of tutorials but nothing gives me what I’m after. Thank you in advance!

Hi there,

I’m abit new to UE4 too, but can you not make havoc emit from an actor within the scene?

massive “fog” nebulae are really… REALLY expensive.
You might want to be sure to lod it into a masked instead of opacityversion of the shader.
If its an actual ring, either make it out of 1-4 meshes (waaaaay more optimal) or let it emit sprites with the cylinder location module. (surface only, disable Z+ and Z-)
