I had similar problems. What worked for me was to increase the Sheets and Beam Count but that also makes the beam brighter. It’s just a workaround and I also would like to know more about that.
I’m using beam emitters tracing splines to create the orbital rings around the sun, but parts of the orbit seem to disappear as the camera moves.
How would I go about fixing/disabling the behavior seen in the right half of the GIF? I’m not worried about performance.
