## Properties

- blurQuality : real
- fadeAmount : real

## Detailed Description

Use ExtendedSceneEnvironment, MultiEffect, or user-defined effects via the Effect type instead.

Warning: All pre-made standalone effects in QtQuick3D.Effects are considered deprecated starting with Qt 6.5. Applications are advised to use ExtendedSceneEnvironment or MultiEffect instead, when applicable, or alternatively provide their own custom post-processing effect via the Effect type.

The MotionBlur effect creates a trailing streak for rapidly moving objects in the scene.

Note: The background mode must be `SceneEnvironment.Transparent` for MotionBlur to work.

## Property Documentation

blurQuality : real

The quality of the blur used to create the trail. Increasing quality will have impact on performance. The range is `[0...1]`. The default value is `0.25`.

fadeAmount : real

How fast the trail fades. The range is `[0...1]`, with `0` meaning that the object trail persists indefinitely, and `1` meaning that the object trail fades out immediately. The default value is `0.25`.
