how to creat light trail for a shape layer like below

[WingsOfEagles]

Can anybody help on below effects? The shape layer is moving from left to right. The parallel light trail following the whole shape and shaded. I tried Edgeray efect but the light is not parallel. Any other effects can use or there is other good way to do this effects?

A copy of the shape or text layer with outlines + Echo, cameras, and lights. Something like this:

I uploaded an AEP file for you to look at.  The more echos you have the longer the render time will be. They have to be close together to get a smooth fade. Pay attention to the keyframe values. Adding an expression control slider multiplied by .0001 makes it easier to fine-tune the delay between echos.

Since this appears to be a creenshot from a game, chances are it's simply based on geometry - the extruded shape of the latter mapped with a gradient and an incidence based shader. That being the case, chances are the best way to appraoch this would be a plug-in like Trapcode TAO. Otherwise you'll have to put upo with tons of duplicate layers, the Echo effect, Directional Blur and heavy treatments for contrast and transparency to re-create this illusion.

Hi Mylenium, thanks for the advice.

Recently, I saw this short video (I attached here a few seconds for your referrence) in a shortvideo platform. It's so interesting that I want to do the same. However, I can't reduplicated it by AE. So this is why I try to find a solution here. Otherwise, I suspect they are using other software which I don't know.

The Echo seems working a bit but not exactly same vision effects as the attached video. Their light is straight and parallel. 

Let's see if their is better solution to do this.
