** 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.
