Highlight Plus 2D · Troubleshooting & FAQ

Common issues and their solutions when working with Highlight Plus 2D.

Effects Not Visible

Possible Cause	Solution
No `HighlightEffect2D` component	Add Highlight Effect 2D to the sprite GameObject.
Highlighted is unchecked	Enable Highlighted in the Inspector, or set `effect.highlighted = true` from script.
No effect enabled	Enable at least one effect (Outline, Glow, Overlay, etc.) in the component.
Sprite sorting hides the effect	Generated effects cannot be assigned a Sorting Layer or Order in Layer. Always On Top only ignores depth occlusion and does not override sprite sorting.
Alpha Cut Off too high	Lower the Alpha Cut Off value so visible pixels are not discarded.

See-Through Not Working

Possible Cause	Solution
Occluder not enabled	The sprite in front must have `HighlightEffect2D` with Occluder enabled.
See-Through not enabled on target	The sprite behind must have See-Through enabled in its `HighlightEffect2D`.

Trigger Not Responding to Pointer

Possible Cause	Solution
Missing collider	Add a `Collider2D` (e.g. `BoxCollider2D`) to the sprite.
No Physics2D Raycaster	Ensure your camera has a Physics 2D Raycaster component (required for UI-based pointer detection).

Sorting Layer Issues

Highlight Plus 2D generates its effects with mesh draw calls and does not currently expose SpriteRenderer Sorting Layer or Order in Layer controls.

Always On Top ignores depth occlusion only; it does not override sprite sorting. Adjust the sprite sorting setup when possible. If the effects need independent camera ordering, assign a dedicated Rendering Layer and use camera culling masks.

Spine / Mesh Renderer Issues

When using Highlight Plus 2D with MeshRenderer (e.g. Spine), enable the Preserve Mesh option in the General section. This uses the original mesh data instead of a generated quad.

Polygon / SVG Sprites Not Rendering Correctly

Enable the Polygon / SVG toggle in the General section when using polygon-packed or SVG sprites.
