Is there a way to replicate this in unity? If not, what’s the closet effect I can get? I have tried the trail renderer, and it kind of look like this but not really.

There are multiple ways of achieving this.

  1. Create a texture along the plane that you want, then use a cutout shader to have it start from one side, and scrolls to the other (think radial progress bar)

  2. You could programmatically create a mesh along the plane of your sword and texture it at the same time.

Either way, this is not an ‘easy’ thing.
