Syntax

class FSkinWeightLookupVertexBuffer : public FVertexBuffer

Remarks

A lookup vertex buffer storing skin weight stream offset / influence count. Only used for unlimited bone influences.

Variables

		Name	Description
	FShaderResource...	SRVValue	Guaranteed only to be valid if the vertex buffer is valid

Constructors

	Name	Description
	FSkinWeightLookupVertexBuffer()	Default constructor.
	FSkinWeightLookupVertexBuffer ( const FSkinWeightLookupVertexBuffer... )	Constructor (copy)

Destructors

	Name	Description
	~FSkinWeightLookupVertexBuffer()	Destructor.

Functions

	Name	Description
void	CleanUp()	Delete existing resources
void	CopyMetaData ( const FSkinWeightLookupVertexBuffer... )
FVertexBuffe...	CreateRHIBuffer_Async()
FVertexBuffe...	CreateRHIBuffer_RenderThread()	Create an RHI vertex buffer with CPU data.
bool	GetNeedsCPUAccess()
uint32	GetNumVertices()
FRHIShaderRe...	GetSRV()
uint32	GetStride()
uint32	GetVertexDataSize()
void	GetWeightOffsetAndInfluenceCount ( uint32 VertexIndex, uint32& OutWeightOffset, uint32& OutInfluenceCount )
void	Init ( uint32 InNumVertices )
void	InitRHIForStreaming ( FRHIVertexBuffer* Intermediate..., TRHIResourceUpdateBatcher< MaxNumUp... )	Similar to Init/ReleaseRHI but only update existing SRV so references to the SRV stays valid
bool	IsLookupDataValid()
void	ReleaseRHIForStreaming ( TRHIResourceUpdateBatcher< MaxNumUp... )
void	SerializeMetaData ( FArchive& Ar )
void	SetNeedsCPUAccess ( bool bInNeedsCPUAccess )	Set if the CPU needs access to this vertex buffer
void	SetWeightOffsetAndInfluenceCount ( uint32 VertexIndex, uint32 WeightOffset, uint32 InfluenceCount )

Overridden from FRenderResource

	Name	Description
FString	GetFriendlyName()
void	InitRHI()	Initializes the RHI resources used by this resource.
void	ReleaseRHI()	Releases the RHI resources used by this resource.

Operators

		Name	Description
	FSkinWeightL...	operator= ( const FSkinWeightLookupVertexBuffer... )	Assumes that vertex buffer will be rebuilt

Constants
