Procedural Eye Swarm Effects

Create stylized supernatural observers, magical sentries, surreal motion graphics, horror ambience, and sci-fi surveillance effects with one focused Unity 6 URP toolkit.

Procedural Eye Swarm Effects combines an authored low-poly eye surface with a custom shader that generates animated iris fibers, concentric micro-rings, veins, pupil response, corneal highlights, wet sheen, rim lighting, and per-eye color variation. The supplied controller builds the swarm at runtime, keeps the eyes focused on an optional world-space target, and moves them through five distinct formations.

Included formations:

- Hero eye with an orbital constellation

- Three-lobed vertical orbit

- Layered gaze tunnel

- Synchronized focus grid

- Spectral double helix

Five ready-made profiles cover azure, violet, crimson, amber, and mixed spectral looks. Every profile exposes sclera color, two iris colors, vein color, pupil scale, vein strength, and emission. The controller supports 1–96 eyes, formation-radius control, deterministic presentation timing, and runtime mode switching through a small public API.

The package includes a polished 30-second demo scene, a reusable swarm rig, a standalone eye prefab, a complete demo setup prefab, documentation, and organized source assets. The demo uses an invisible Transform as its gaze target, so there is no unwanted marker or runtime-hidden presentation geometry.

Validated in Unity 6000.0.30f1 with URP 17.0.3 and Render Graph enabled. URP only. No Visual Effect Graph, TextMesh Pro, external models, third-party runtime libraries, or flipbook textures are required.
