“This Weapon Is Your Life” --Obi-Wan Kenobi
For real applications I would definitely create custom shader for saber blade glow to better control core, secondary color and overall bloom. Similar to how I did fake Rayleigh scattering effect and eclipse in my planet shader. For this small toy project though I kept it simple. Bloom here is not really good at far distances and on closeups jagged edge is apparent.
