Thank you for taking time to response JBrookes, but I’m not sure I follow. In your snippet, you seem to position the particles around the camera and then moving the particles past the camera, while the idea is to have a moving camera (ship) and then particles that sit still in space which you go past, in any direction, not just z.

I feel I’m missing something obvious here.

You don’t need all that.
create a single particleField

then in the renderloop

cloud.copyTransform(camera);

loop through the particles and move the z position
reset z position when particle goes behind camera.

You can do all that and the skybox in under 100 lines.
post on the forum PV forum if you want to know more.
