Technical details

Sharp Shader keeps shader logic in ordinary C# and generates HLSL inside the Unity workflow.

Key features:

shader logic written in C# and converted into HLSL;
generated per-file HLSL outputs inside Assets/ShaderGen;
function, struct, and constant generation;
Shader Graph nodes generated for explicitly marked functions;
IDE-friendly workflow with normal autocomplete, hover, navigation, and compiler feedback;
testable and debuggable shader logic through ordinary Unity and .NET tooling;
AI-development-friendly workflow because shader logic stays in normal C# units and can participate in project tooling and static analysis;
explicit diagnostics for unsupported source forms;
built-in helper surface for constructor-style forms, explicit helper conversions, reinterpret helpers, and masked selection;
texture, sampler, and resource surface in SharpShader.Hlsl;
CPU-side runtime stubs and emulation helpers in SharpShader.Runtime for selected shader-facing behavior;
Unity.Mathematics as the CPU-side backing for shader-oriented numeric code and stubs;
asmdef-aware generator placement for multi-assembly Unity projects;
