GraphicsSettings.GetSettingsForRenderPipeline

描述

Get the registered RenderPipelineGlobalSettings for the given RenderPipeline.

This method iterates over all RenderPipelineGlobalSettings registered in the GraphicsSettings. If there is an instance registered for the given RenderPipeline, the method returns it, otherwise the method returns null. The function performs string comparison and may allocate memory. To improve runtime performance, cache the result of the function call.
