GraphicsSettings.GetSettingsForRenderPipeline

参数

返回

针对给定管道注册的 RenderPipelineGlobalSettings RenderPipelineGlobalSettings 资产。

说明

获取针对给定 RenderPipeline 已注册的 RenderPipelineGlobalSettings。

此方法会遍历 GraphicsSettings 中注册的所有 RenderPipelineGlobalSettings。如果为特定 RenderPipeline 注册了一个实例，此方法会将其返回，否则该方法会返回 null。此函数执行字符串比较并可能会分配内存。为提高运行时性能，应缓存函数调用的结果。
