Lights 模块

使用此模块可将实时光照添加到一部分粒子。

Using the Lights module

This module is part of the Particle System component. When you create a new Particle System GameObject, or add a Particle System component to an exiting GameObject, Unity adds the Lights module to the Particle System. By default, Unity disables this module. To create a new Particle System and enable this module:

1. Click GameObject > Effects > Particle System.
2. In the Inspector, find the Particle System component.
3. In the Particle System component, find the Lights module fold-out.
4. To the left of the fold-out header, enable the checkbox.

API

Since this module is part of the Particle System component, you access it through the ParticleSystem class. For information on how to access it and change values at runtime, see the Lights module API documentation.

属性

For some properties in this section, you can use different modes to set their value. For information on the modes you can use, see Varying properties over time.

详细信息

Lights 模块是一种为粒子效果添加实时光照的快速方法。此模块可用于使系统将光照投射到周围环境，例如可用于火、烟花或闪电。此外，还可通过该模块让光照从所附着的粒子继承各种属性。这样可以使粒子效果本身的发光更加逼真。例如，为了实现此目的，可使光照随其粒子淡出并使它们共享相同的颜色。

该模块可以非常快速地创建大量实时光照，但实时光照有很高的性能成本，尤其是在前向渲染模式下。如果光照还要投射阴影，性能成本会更高。为了防止意外调整发射速率并因此导致创建数千个实时光照，应使用 Maximum Lights 属性。创建的光照数量超过目标硬件的管理能力可能会导致速度降低和无响应的问题。
