Functions

Name Description

Public function

bool

 

BuildResourceTableMapping

(
    const TMap< FString, FResourceTable...,
    const TMap< FString, uint32 >& Res...,
    TBitArray<>& UsedUniformBufferSlot...,
    FShaderParameterMap& ParameterMap,
    FShaderCompilerResourceTable& OutS...
)

This function looks for resources specified in ResourceTableMap in the parameter map, adds them to the resource table, and removes them from the parameter map.

Public function

void

 

BuildResourceTableTokenStream

(
    const TArray< uint32 >& InResource...,
    int32 MaxBoundResourceTable,
    TArray< uint32 >& OutTokenStream,

Finds the number of used uniform buffers in a resource map.

Public function

void

 

RemoveUniformBuffersFromSource

(
    const FShaderCompilerEnvironment& ...,
    FString& PreprocessedShaderSource
)

The cross compiler doesn't yet support struct initializers needed to construct static structs for uniform buffers Replace all uniform buffer struct member references (View.WorldToClip) with a flattened name that removes the struct dependency (View_WorldToClip)

Public function

bool
