Use a Projector component to create effects such as:
Note: This workflow is compatible only with the Built-in Render Pipelne. For similar functionality in other render pipelines, see Decals and projectors.
A Projector works by projecting a material onto all objects that intersect its frustum. The material must use the Projector/Light or Projector/Multiply shaders, available in Unity’s Standard Assets.
When configuring a material to use with the Projector/Light and Projector/Multiply shaders, be aware of the following:
剪影纹理:
衰减纹理(如果存在):
标准资源 (Standard Assets) 包含的示例预制件演示了 Projector 组件的使用。
要使用预制件,请执行以下操作:
可以按原样使用预制件,对预制件进行修改,或检查预制件的配置。
