Add polished, texture-free animated highlight sweeps to Unity uGUI elements with independent color, width, softness, angle, brightness and timing controls.UI Shimmer and Shine Effects is a lightweight animated highlight system for Unity uGUI and URP. Add the supplied component to an Image, RawImage or legacy Text Graphic, assign the shared material, and tune the look directly in the Inspector.Each element keeps independent color, width, softness, angle, brightness, speed, phase and manual progress values while all supplied prefabs share one material. Per-element settings are stored in additional UI vertex channels, so preset variation does not require a unique material for every Graphic.The shader retains the standard uGUI stencil, rectangular clipping, alpha clipping and sprite-atlas behavior. It works with Screen Space Overlay, Screen Space Camera and World Space canvases. The runtime component automatically enables the Canvas vertex channels it needs and safely manages a temporary fallback material only when no compatible material is assigned.The package includes four reusable presets—Hero, Spectral, Aurora and Solar—plus a ready-to-run showcase setup and demo scene. The included small rounded-panel sprite is used by the examples; the shimmer itself requires no source texture or Shader Graph.- Unity version: 6000.0.30f1- Render pipeline: Universal Render Pipeline 17.0.3- UI dependency: Unity UI (uGUI) 2.0.0- Reusable prefabs: 4- Demo setup prefabs: 1- Demo scenes: 1- Shared materials: 1- Runtime scripts: 1- Custom shaders: 1- Demo/preset textures: 1 PNG, 96x96- Documentation: README and full manual- Supported Graphics: Image, RawImage and legacy Text- Canvas modes: Screen Space Overlay, Screen Space Camera and World Space- Masking support: uGUI stencil, RectMask2D clipping and alpha clipping- Demo media: six 2560x1440 screenshots and one 2560x1440, 60 fps, 30-second H.264 videoAI was used during code refactoring and scene setup.
