GraphicsSettings.currentRenderPipeline

Description

The RenderPipelineAsset that defines the active render pipeline for the current quality level.

The active render pipeline is the render pipeline that Unity is currently using to render your application and parts of the Editor such as the Scene view and Game view. The active render pipeline can be a default value, or you can set override values for different quality levels.

The default value is defined in GraphicsSettings.defaultRenderPipeline. The override value for the current quality level is defined in QualitySettings.renderPipeline.

If the default value is not defined, then the active render pipeline is the Built-in Render Pipeline. Otherwise, if an override value is defined for the current quality level, the active render pipeline is the override value; if no override value is defined for the current quality level, it is the default value.
