Question by Roland09 · Jun 03, 2016 at 06:16 AM · glow

How do you make a proper lightsaber / glowing cylinder that looks good from any angle?

I'd like to create a lightsaber / neon tube, i. e. a glowing object. I already tried several things, but none of them are good.

I searched and found suggestions like e. g. using a line renderer. But a line renderer looks depending on the angle like a flat ribbon.

Even the volumetric lights asset doesn't work. For one it also looks like a flat ribbon:

And for the other the light is distorted at some point:

The suggestion with the bloom effect doesn't work either. Unfortunately I get a "no more attachments allowed for this question" error now, so I can't show. When you use bloom the light kind of moves / pulsates when you move the object. And besides of that you see severe aliasing of the object when you use bloom on it.

Try this free asset:

It is not mine, but I have tested it and works perfectly. No need to use HDR and bloom.

I already tried that. The problem is that I need it with S$$anonymous$$mVR. And it doesn't work with the stable version of Unity & S$$anonymous$$mVR, but it does work with the latest Unity beta. So I'll keep it at that. Thanks!
