效果示例
打开此开关后，Cook过程中，将会看到例如以下报错：
LogShaderCompilers: Error: Errors compiling global shader FInstanceXXCS :
LogShaderCompilers: Error: /Engine/Private/Mobile/XXData.ush(31): warning: The macro is redefined
#define PRIMITIVE_SCENE_DATA_X 29

previously macro "PRIMITIVE_SCENE_DATA_STRIDE" defined as: #define PRIMITIVE_SCENE_DATA_STRIDE 66 /* /Engine/Shared/SceneDefinitions.h:80 */
LogOutputDevice: Warning:
其中 Engine/Private/XQuery.usf 的路径全称是：
EngineSource/Engine/Shaders/Private/XQuery.usf
开关的打开方式
Engine/Config/ConsoleVariables.ini 中，将
;r.DumpShaderDebugInfo=1 改为
r.DumpShaderDebugInfo=1
也就是反注释。
