Hi Jeremy, thank you for taking your time on this. I tried the vegas effect in the comp that I am working on and it looks quite well. You are right that the beam’s width is pretty constant, but I think it quite close for now.

Someone on the adobe forum suggested using the Trapcode 3D Stroke or Cinema 4D Lite, in case you want to try that; I am not very familiar with those yet, but I might give them a try as well.
