UI Toolkit Shadows, Outlines & Glow v1.3.4 provides glow, outlines, and soft shadows for UI Toolkit elements. The effect is achieved through vertex color manipulation, not via shaders, so it does not support bloom effects. Users can choose two colors to create either a glow (when colors differ) or an outline (when colors are the same). Real box shadows can be applied using the Shadow control, or shadows can be emulated using non-destructive glow manipulators. The workflow is non-destructive and does not require changes to existing UI hierarchies—components can be added directly to any UI element. Custom glow attributes allow control over properties via USS (UI Toolkit Style Sheets). Features include inheriting border colors, splitting glow width on each side, and storing glow configurations and animations in Scriptable Object assets for easy reuse and script modification. Animation presets are available, and full vertex-level customization is possible with coding (examples provided). The resource supports URP, HDRP, and Built-In rendering pipelines without requiring custom shaders. Full source code is included, with clear attribution for MIT-licensed components. The asset is compatible with Unity 2021.3 and later, including all LTS versions, though earlier versions are not officially supported. Documentation and examples are available in the GitHub repository: https://assetstore.unity.com/packages/2d/gui/ui-toolkit-shadows-outlines-glow-265521.
