This is mainly a texture and lighting question. I'm trying to recreate the light tracers shown in the first three of the attached images. The fourth image is my attempt. As you can see, my tracers don't have that blurry glow that the example images have. How can I achieve that glowy-blurry-luminescent quality?
Are these effects possibly done in After Effects?
