Lightsaber Blade Shader

This model was designed in Cycles and never tested in Eevee. It might get a bit of adjusting to get it to look as great in your scenes as it does in mine, but with the well-documented node structure, it should be easy to edit it on the fly. The file includes a regular lightsaber, one that matches Kylo Ren's lightsaber, and a blaster bolt. It even has a useful "contact point" tool, for showing those bright flashes that lightsabers emit whenever they hit another lightsaber.

I might add more to this in the future, but definitely don't count on it.
