So I have a question for everyone. Demon Souls Remaster was recently released on the PS5 and the game looks awesome. Hopefully you can see the moon blade in this GIF I linked, and I was wondering if anyone other than UE4 knew how to do this effect. To me it looks like a vector field but is attached to the weapon. When the weapon moves, the effect doesn't move on the handle, but leaves a trail at the end of the blade.
If anyone has an idea, thank you in advance
