Syntax

struct FVulkanShaderHeader

Name	Remarks	Include Path	Unreal Specifiers
FVulkanShaderHeader ()		VulkanShaderResources.h
FVulkanShaderHeader ( EInit )		VulkanShaderResources.h

Name	Remarks
FBindingInfo	Includes all bindings, the index in this array is the binding slot.
FGlobalSamplerInfo
FInputAttachmentInfo	Used to determine the EAttachmentType of a FBindingInfo with type VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT.
FUniformBufferInfo	FBindingInfo with type VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER have a corresponding entry in this table (at the same index)

Name	Remarks
EAttachmentType	The order of this enum should always match the strings in VulkanBackend.cpp (VULKAN_SUBPASS_FETCH)
EGlobalSamplerType	Types of Global Samplers (see Common.ush for types) Must match GetGlobalSamplerType() in SpirVShaderCompiler.inl and and declarations in VulkanCommon.ush
EInit
ERayHitGroupEntrypoint	For RayHitGroup shaders.
