Highlight Plus is a complete highlighting, selection, and visual feedback system for Unity. Add outline, glow, see-through (X-ray), overlay, target indicators, hit FX, and more to any 3D object - with zero code required for basic use and a full C# API for advanced control.

Key Features

  • Outline - crisp contour lines with four quality levels (Fastest, Medium, High, Highest)
  • Outer Glow - bloom-like glow with multi-pass color control
  • Inner Glow - rim-lighting effect rendered inside the mesh
  • See-Through (X-Ray) - reveal occluded objects behind walls and geometry
  • Overlay - pulsing color wash with optional texture patterns
  • Target FX - animated ground decal or rotating sprite indicator
  • Hit FX - brief color punch on impact
  • Selection System - click-to-select with per-state profiles via Highlight Manager
