Nice job - I downloaded the prop to check it out. You forgot to disable shadows for the blade, but that's easy enough for the user to do.

Here's a render of it laying on the ground. I found that increasing the scale of the blade (x and z) to 150% inhances the glow - it was a little tight by default.

Also I lowered the transparency on the innermost two mat zones. Gives a bit of sharper look to the core of the beam.

I also added a bit of Fresnel reflection to the hilt.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
