I think its because my animations are choppy, I just tried it on a smoother animation and the edges were fine. It’s probably not noticeable anyways to make much of a difference so I’ll just leave it. Thank you for your help!
This seems like an optimization thing that roblox does.
Try setting your graphics higher and you’ll see the change
Though if for some reason, its still jagged and your graphics are at max, it might be because of the animation moving very fast. (which can cause a large gap that it has to fill in or sharp edges)
It’s a couple issues. The first issue is the animation, which in itself is really janky.
The bigger issue, though, is the fact you are using the default texture. Use something that isn’t 100% as wide as the trail itself. Doing a proper texture will break the illusion.
