Stylized Rainbow Trails

The Stylized Rainbow Pack is a ready-to-go VFX Graph for Unity (6.0+) URP that makes it insanely easy to add living, breathing rainbows to your scenes. Drop in one optimized Graph and choose between three prefab styles—endless loops, elegant S-curves, or smooth continuous arcs—then pick from thirty handcrafted gradients (neons, pastels, and everything in between) via a simple slider or swap in your own.

Beyond color and shape, everything is exposed: particle spawn rate, trail thickness, glow size/alpha, noise-driven turbulence, burst velocity, even how tightly the trail hugs its control-point curve. You get up to four user-assigned Transforms (A–D) to sculpt your own Bezier path—just drag any GameObject into those slots, tweak its position/rotation/scale, and watch your rainbow weave through the world.

Included is a polished demo scene with animated camera fly-throughs so you can preview every style and gradient instantly. Under Unity’s standard license and compatible only with URP on 6.0+ —perfect for everything from small indie levels to epic VR adventures. 🌈
