I have looked at many different things including THIS which is the exact question I want, but even that didn't work. I'm trying to render a lightsaber. I've made a green emission material bright enough that it looks white in the middle but in order for it to look like a lightsaber, it needs to be hitting something.
Obviously I don't want to animate a Jedi holding a lightsaber with a plane behind it the entire time. I would like to know how to render the light that hits an object without rendering said object. Thanks in advance!
Luke D - I have watched many lightsaber blender tutorials. That's what got me this far. All of them have been for a still image not animation. Can you not make an object invisble but let light hit it?
