You can use Visual Studio to debug shaders in a Unity application on Windows platforms using DirectX 11 or 12. This page contains information on how to do this.
注意
If you are using DirectX 12, Microsoft recommends that you use PIX to debug shaders instead of Visual Studio. For information on using PIX on Windows with Unity, see Debugging shaders using PIX.
Preparing your shaders
To debug shaders, you must compile them with debug symbols included. To do that, insert the directive into the source code of each shader that you want to debug.
#pragma enable_d3d11_debug_symbols警告
This pragma directive can negatively affect performance. Remove it from your shader code before you make a final build. For more information on this pragma directive, see Shader compilation: pragma directives.
Creating a placeholder Visual Studio project for Windows Standalone
If you build your application for Windows Standalone, you must create a placeholder Visual Studio project. If you build your application for Universal Windows Platform, Unity generates a Visual Studio project for you.
- Launch Visual Studio.
- Go to File > New > Project > Visual C++ > Empty Project.
- Go to Project > Properties > Configuration Properties > Debugging
- In the Command field, replace $(TargetPath) with the path to your Windows Standalone application (for example, C:\MyApp\MyApp.exe)
- If you want to force the project to run under DirectX 11, select Command Arguments and type -force-d3d11.
