MME Authoring

Overview

Write MME shader code from a concrete plan. Follow local examples and keep the first implementation debuggable.

Before Writing

Confirm the plan includes:

• File paths and include paths.
• Attachment/load instructions.
• Render target definitions.
• Technique/pass graph.
• Controller/UI parameters.
• Shader model target.
• Example source files.

If any of these are missing for a nontrivial effect, return to mme-implementation-planning.

Authoring Rules

• Preserve existing framework layout and include conventions.
• Use ASCII filenames for new effect files when possible.
• Keep comments concise and useful; explain pass purpose, not obvious assignments.
• Preserve MMDSamp0, MMDSamp1, MMDSamp2 declarations when adapting full shaders.
• Put Draw=Buffer or Draw=Geometry on pass Script.
• Use vs_2_0/ps_2_0 for simple model passes; use vs_3_0/ps_3_0 for complex postprocess, loops, SSDO/SSAO, or framework parity.
• Add temporary debug output passes for complex intermediate buffers if runtime testing is expected.
• For model shaders, include all needed MMDPass variants and material resource variants.
• For framework work, prefer extension points and preset patterns over core rewrites.

Minimal Postprocess Shape

float Script : STANDARDSGLOBAL <
    string ScriptOutput = "color";
    string ScriptClass = "scene";
    string ScriptOrder = "postprocess";
> = 0.8;

texture2D ScnMap : RENDERCOLORTARGET < float2 ViewPortRatio = {1,1}; >;
texture2D DepthBuffer : RENDERDEPTHSTENCILTARGET < string Format = "D24S8"; >;

technique Main <
    string Script =
        "RenderColorTarget0=ScnMap;"
        "RenderDepthStencilTarget=DepthBuffer;"
        "Clear=Color;"
        "Clear=Depth;"
        "ScriptExternal=Color;"
        "RenderColorTarget0=;"
        "RenderDepthStencilTarget=;"
        "Pass=DrawFinal;";
> {
    pass DrawFinal < string Script="Draw=Buffer;"; > {
        VertexShader = compile vs_3_0 VS();
        PixelShader  = compile ps_3_0 PS();
    }
}

Adapt from official examples rather than using this as a full template for production.

After Writing

Immediately use mme-static-review. Do not claim the shader is correct until it has been reviewed and, when possible, tested in MMD/MME.
