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.
Note: 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.
To debug shaders, you must compile them with debug symbols included. To do that, insert the
#pragma enable_d3d11_debug_symbols directive into the source code of each shader that you want to debug.
Warning: 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.
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.
For instructions on setting up Visual Studio, see the Microsoft documentation: Install Visual Studio.
For instructions on setting up and using Visual Studio’s graphics debugging tools, see the Microsoft documentation: Visual Studio Graphics Diagnostics.
