Mesh Trail Generator - a slick Geometry Nodes setup I built in Blender for whipping up killer trails on any moving object. Think sword slashes, spaceship exhaust, or magic whips with fire, plasma, energy bursts in cyan, pink, yellow—you name it, all mesh-based for that solid look without actual particles eating your viewport. Slap it on as a modifier and dial in length, fade speed, density right in the panel; scales to real-world sizes and runs smooth even in big scenes. Works on Blender 4.0+, comes with this thumbnail for previews. Grab it for your VFX gigs, games, or motion stuff-super tweakable and no fuss.
