Lens Flare component
A Lens Flare component displays a lens flare that is configured by a Flare asset.
You can display a Flare asset with a Light component. If you do this, Unity automatically tracks the position and direction of the Light and uses those values to configure the appearance of the lens flare.
Use this component instead to configure the values of the lens flare yourself, which gives you more precise control.
Note: This workflow is compatible only with the Built-in Render Pipelne. For similar functionality in other render pipelines, see Lens flares and halos.
Using a Lens Flare component
1.创建一个新的__游戏对象__（菜单栏：__GameObject > Create Empty__）。 2.在 Inspector 中单击 Add Component > Effects > Lens Flare。 3.为 Flare 属性指定一个光晕资源。 4. If you want a Camera to see lens flares, attach a Flare Layer component to the Camera’s GameObject. 5. To see the lens flare effect in the Scene View, enable the Effect toggle in the Scene View toolbar and, in the drop-down, enable Flares.
