Highlight Plus is a powerful and versatile asset for adding outline, glow, overlay, see-through, and other highlight effects to objects and characters in your scene.
Designed with platform compatibility and performance in mind, Highlight Plus is the go-to choice for developers seeking high-quality visual enhancements that are both easy to implement and efficient.
** Visual Effects **
Combine any number of effects on single or multiple objects from a single script:
- Outline: 4 quality levels including mesh-based instancing rendering and screen-space with optimal blit region. Customizable color, alpha, width, gradient, visibility options (normal, always in front, behind) and more.
- Outer Glow: great for per-object bloom and aura effects. 4 quality levels, also mesh-based instanced rendering and screen-space with fully customizable controls including visibility, smooth or noise/dither effect, animation, blending, mask and more.
- Inner/Rim Glow: with customizable color, width, blend modes, intensity and visibility.
- Overlay: color or textured overlay with different uv mapping options, alpha and animation speed, custom blending options.
- Target: add aiming or special indicators on specific parts of any gameobject with fully control of animation and appearance details, like colors, texture, transitions, etc.
- Area of effect: target effect option which adds an aligned to ground animated graphic under a gameobject or character (similar to decals).
- See-Through: reveal objects or characters behind solid occluders. Customize intensity, tint color and alpha. Occluded objects keep their correct depth. Plus additional colored border option.
