best way create a light traveling down a fibre optic path please help

Question

hi guys I am trying to create something similar to this, im hoping someone can give me a bit of advice on the best way to go about this task.

few questions that would help my learning:

1. regarding paths, do i make them in illustrator and import to shapes, or is there way i can replicate the illustrator brushs.

2. Are the paths 3d layers, or would it be better to make them on 3d layers

thanks in advance

Let's start with the basics. CC 2021 can create tapered lines. Bevil Alpha can simulate a tube, Dashes, Gaps, and Offset can create movement in the lines. Glow and Motion blur can add to the effect. The bottom path was created first, then duplicated and dashes, gaps, and offset were set up, the color changed and the width, then the blend mode was set to add and glow and CC Force Motion blur polished up the look. This took me less than 5 minutes using the rotobezier pen tool on a shape layer. I'm showing you all of the settings including the time - 1800 expression is in Offset to make the dashes move.

That is only one of about 20 ways I can think of to make this happen without any 3rd party plugins. The best workflow depends on your design. AI paths can be copied and pasted. Simple AE paths without brush strokes can be converted to shapes that just have a path. There are lots of ways to create something like your example.
