r.ShaderCompiler.DebugDumpDetailedShaderSource

If true, and if the preprocessed job cache is enabled, this will dump multiple copies of the shader source for any job which has debug output enabled: 1. The unmodified output of the preprocessing step as constructed by the PreprocessShader implementation of the IShaderFormat (Preprocessed_.usf 2. The stripped version of the above (with comments, line directives, and whitespace-only lines removed), which is the version hashed for inclusion in the job input hash when the preprocessed job cache is enabled (Stripped_.usf) 3. The final source as passed to the platform compiler (this will differ if the IShaderFormat compile function applies further modifications to the source after preprocessing; otherwise this will be the same as 2 above (.usf) If false, or the preprocessed job cache is disabled, this will simply dump whatever source is passed to the compiler (equivalent to either 1 or 3 depending on if the IShaderFormat implementation modifies the source in the compile step.
