So I wanted to create a 2D blade with a simple trail renderer that follows the edge of the sword. I figured it'd be fairly easy, since it's pretty much one of the most typical uses of a trail renderer. Alright, so far so good. I move the sword up and down, and it does its thing, mostly. However, it soon became clear to me that it was seemingly impossible to sort of 'parent' the trail renderer to the edge of the blade, since the trail renderer rotates like crazy in whatever direction it wants to go in. How the heck do I keep the trail renderer oriented to the edge of the blade, and not just spin like crazy and create ugly sharp lines? Another bit of weirdness is that the trail renderer texture FLIPS if I am moving down as opposed to up, which feels like a bug to me. tl;dr: I thought a local space trail renderer that I can kept oriented to the edge of a blade would be easy out of the box; it seems like it's not even an option? Is there a method to achieving this that I'm not seeing?
