Variables

Public

Name Type Remarks Include Path Unreal Specifiers
bDisableOptimizations bool Force to turn off optimizations. Ignore optimizationLevel below. ShaderConductorContext.h  
bDisableScalarBlockLayout bool Disables scalar block layout for structured buffers. ShaderConductorContext.h  
bEnable16bitTypes bool Enable 16-bit types, such as half, uint16_t. Requires shader model 6.2+. ShaderConductorContext.h  
bEnableDebugInfo bool Embed debug info into the binary. ShaderConductorContext.h  
bEnableFMAPass bool Enable a pass that converts floating point MUL+ADD pairs into FMAs to avoid re-association. ShaderConductorContext.h  
bEnableSeparateSamplersInGlsl bool Enables separate samplers in GLSL via extensions. ShaderConductorContext.h  
bForceStorageImageFormat bool   ShaderConductorContext.h  
bPackMatricesInRowMajor bool Experimental: Decide how a matrix get packed. ShaderConductorContext.h  
bPreserveStorageInput bool Preserve storage inputs used for OpenGL ShaderConductorContext.h  
bRemoveUnusedGlobals bool Removes unused global variables and resources. ShaderConductorContext.h  
bSupportPreciseOutputs bool Decorate output semantics as precise. ShaderConductorContext.h  
bSvPositionImplicitInvariant bool Decorate SV_Position implicitly as invariant. ShaderConductorContext.h  
bWarningsAsErrors bool Treat warnigns as errors. This adds '-WX' to the DXC arguments. See CFLAG_WarningsAsErrors. ShaderConductorContext.h  
HlslVersion uint32 HLSL language input version: 2015, 2016, 2017, 2018 (Default), 2021 (Breaking changes in short-circuiting evaluation). ShaderConductorContext.h  
ShaderModel FHlslShaderModel Shader model version of the input language. By default SM6.2. ShaderConductorContext.h  
SpirvCustomOptimizationPasses FString SPIR-V specific optimization passes to override the default '-O' argument. ShaderConductorContext.h  
TargetEnvironment ETargetEnvironment   ShaderConductorContext.h
