About UIFX - Trail

Overview

What?

UIFX-Trail is a new visual effect for Unity's UI (uGUI) components that adds a trail that follows the motion of the component.

Why?

Unity's UI system currently doesn't have an option to render with a trail.

Trails can be beautiful and add an element of fun, so we created this component to be easy to use, yet have powerful options.

How?

Just add the UIFX-Trail component to your UI component. That's it!

The component will track the full motion of the object (translation, rotation and scale) either at a transform level, or at a per-vertex level. A new mesh is then generated based on the motion, and this is rendered in place of the original UI geometry. The effect is only applied when the object is in motion.

Usage

High Damping

Damping can be set to a high value to make the trail follow the original motion more closely.

Low Damping

Damping can be set to a low value to make the trail lag further behind the original motion.

Strength

Strength can be used to transition the trail on or off.

Animated Gradient

OffsetSpeed animates the gradient.

“Beautiful, fast, optimized, great docs, great updates. AAA+”

A Must-Have Plugin for Stunning UI Trail Effects. As others have mentioned, this plugin gives Unity UI a fantastic facelift with minimal effort. I tested it with Procedural UI by DTT, and not only did it work seamlessly, but it animated flawlessly as well. It's mobile-friendly, compatible with Unity 6 preview, and comes with excellent support—just like other high-quality plugins. A perfect addition to any project looking to add smooth, beautiful UI effects!

UIFX is hella fun to use and best way to add characteristic to UI! Amazing and quick support! within a day creator implemented framerate independent option and send it to me, now UIFX is my favorite UI effect! As a motion designer, I always craving for more effect that I can use on UI, and UIFX delivered so much more.

Performance

UIFX-Trail has had several optimisation passes, so we can say with confidence that it is highly performant. That said, it does rebuild a new mesh each frame, so some consideration is still necessary.

Garbage Collection

This component has been optimised to reduce garbage generation.
