I am trying to do the Blender Guru Neon tutorial, all good EXCEPT I can't figure out the glare node set up. I have mine set up just like his tutorial shows, but in mine the glare only shows as a preview in the compositing window, does not show up in final render. I have attached a picture of the compositing window view and a shot of the render (bottom).
I am a total noob - I must have something set up wrong. Anybody have any ideas?
