I'm making a lightsaber in Cycles Render.
I'm pretty new to blender and only started yesterday.
I've been watching YouTube Videos but usually I can't access something they have and usually messes it up.
I'm fine doing compositing and Nodes I just need to know how to make this glow,
Current (v)
Nodes
Current Compositing Nodes

Again I just need this to glow but i keep on messing up! Please help, thank you
