ShadowDusk.MgcbPlugin

A MonoGame Content Builder (MGCB) content-processor plugin that compiles your .fx shaders with ShadowDusk, inside MGCB's own process — no mgfxc, no fxc.exe, no Wine, no Windows SDK. It works on Linux, macOS, and Windows build agents alike.

This is a delivery shape of the ShadowDusk compiler library, not a second compiler. The processor builds a CompilerOptions from MGCB's build context and calls the same EffectCompiler the ShadowDusk CLI and the runtime API call, so the .mgfx bytes inside the .xnb are byte-for-byte what the CLI emits for the same source and target.

MGCB compiles .fx in-process and never launches an external effect compiler, so putting a drop-in mgfxc on PATH does not route an .mgcb build through ShadowDusk. This plugin is the route.

Install

dotnet add package ShadowDusk.MgcbPlugin

It is a build-time (DevelopmentDependency) package: nothing from it ends up in your shipped game assembly.

Use

Add a /reference: line to your .mgcb, then select the ShadowDusk importer and processor on each effect:

/reference:$(NuGetPackageRoot)shadowdusk.mgcbplugin/<version>/tools/net8.0/any/ShadowDusk.MgcbPlugin.dll

#begin MyEffect.fx
/importer:ShadowDuskEffectImporter
/processor:ShadowDuskEffectProcessor
/build:MyEffect.fx

MGCB's /reference: needs a real path, so spell out the package-cache path (or copy the tools/net8.0/any directory somewhere stable in your repo and point at that). Everything the plugin needs — the ShadowDusk assemblies and the pinned DXC, SPIRV-Cross, and vkd3d-shader natives — ships in that one directory.

Nothing else is required. The target is derived from the content project's own /platform: line, and the output is the backwards-compatible MGFX v10 container that every MonoGame 3.8.1.263+ and KNI runtime loads.

.mgcb /platform: ShadowDusk target
Windows DirectX 11 (DXBC SM5)
DesktopGL, MacOSX, iOS, Android, RaspberryPi, Web, NativeClient OpenGL (GLSL)
PlayStation4, PlayStation5, XboxOne, Switch, Xbox360, Stadia not supported — fails loudly

Processor parameters

Every one is optional; the defaults are the correct path.

/processorParam: Default What it does
DebugMode Auto Auto follows the content build configuration, exactly like MonoGame's stock EffectProcessor. Debug / Optimize force it.
Defines (empty) Preprocessor macros, in mgfxc's /Defines: spelling: NAME=VALUE entries separated by ; or ,; a bare NAME defines it as 1.
IncludeDirs (empty) Extra #include search directories, ;-separated. The including file's own directory is always searched first.
ShaderProfile (empty) Escape hatch. Overrides the target derived from /platform:. DirectX_11, DirectX_12, OpenGL, Vulkan — needed only for MonoGame's WindowsDX12 / DesktopVK runtimes, which MGCB's platform list cannot name.
MgfxVersion 10 Escape hatch. 11 opts into the newer MGFX container (MonoGame 3.8.5+).
DxbcBackend vkd3d Escape hatch. d3dcompiler opts into the Windows-only correctness oracle for the DirectX target.

Diagnostics

Shader errors surface through MGCB in the file(line,col-col): error CODE: message form fxc/mgfxc use and MSBuild and IDEs parse, with the underlying compiler's own words verbatim beneath. The build fails; nothing is silently swallowed.
