Screenshots

Avatar Terminus, from the Long Piercing Ion Beams and really liked the long smooth look that resulted from stretching a normal ion beam to 20 times its normal length and asked if that look could be replicated without having the beam pierce the target. I found a mesh that mapped only one copy of the ion beam texture onto itself, not 11 copies like the original ion beam mesh, and, after a few bits of arithmetic and some spelling errors, came up with this.

Instructions

Unzip smoothion.zip into your Homeworld directory. It will put files into the ETG directory that replace the original ion cannon bulletEffects. No further setup is required.
