using UnrealBuildTool;

// The material-graph-building core: turns a parsed .usl model into a UMaterial expression graph and
// triggers its compile. This is needed whenever the engine runs UNCOOKED data — the editor, AND a
// `-game` / Standalone launch on the editor binary against an uncooked project (GIsEditor == false).
// It must NOT be an `Editor`-type module (those are gated on GIsEditor and never load in `-game`, which
// left base materials as empty shells and made instances fall back to the default material). `UncookedOnly`
// loads iff `!RequiresCookedData()`, i.e. exactly the uncooked runs, and is excluded from cooked builds
// (where instances carry their own shader maps and the runtime module's ApplySettings path suffices).
//
// Deliberately depends only on Engine/RenderCore/RHI/Projects/Json — NO UnrealEd/MaterialEditor/Slate —
// so it is safe to load in `-game` where those editor-UI modules are not initialized. The editor-only UX
// (factory, VSCode button, hot-reload watcher, open-editor refresh) stays in UShaderLabEditor.
