Create animated radial speed lines on a reusable mesh surface. Control inward/outward motion, opacity and intensity with three presets and a clean, texture-free demonstration.Radial Speed Lines VFX URP creates animated additive speed lines on an XY mesh surface. Signed speed drives inward or outward motion with phase-continuous changes; opacity and intensity controls support fading the effect away.Three presets and a saved, texture-free demonstration on black keep the effect itself in focus. A four-page PDF manual explains setup, aspect ratio, clock behavior, per-renderer control and property-block ownership.This is a depth-tested mesh effect, not a fullscreen renderer feature, UI masking system, measured motion blur or particle simulation. Opaque scene depth can occlude it. The historical concept reference is MirzaBeig/Anime-Speed-Lines; its retained Unlicense and source notices are included, while upstream Amplify content and media are excluded according to the source record.Target: Unity 6000.0.30f1, Universal Render Pipeline 17.0.3.Additive, depth-tested radial-line mesh shader with signed inward/outward speed, opacity and intensity.Three native presets with authored surface dimensions preserved; single-quad demonstration without textures or labels.Four-page PDF manual covering aspect, clock, ownership and platform limits.Preparation checked signed radial motion, phase continuity, independent renderer controls, zero opacity/intensity, zero-speed freeze, opaque occlusion and pre-enable property-block restoration.Not a fullscreen renderer pass, UI masking system, physical motion blur or particle simulator.AI was used during code review/refactoring, Unity integration, scene preparation, validation and documentation drafting. Historical concept references and retained third-party license notices are documented. Showcase media was captured from the Unity demonstration.
