[edit] Properties

[edit] Property group 'Texture2D'

[edit] AddressX

Type: Texture.TextureAddress

The addressing mode to use for the X axis.

[edit] AddressY

Type: Texture.TextureAddress

The addressing mode to use for the Y axis.

[edit] bGlobalForceMipLevelsToBeResident

Type: bool

Modifiers: const

Global/ serialized version of ForceMiplevelsToBeResident.

[edit] Internal variables

[edit] bForceMiplevelsToBeResident

Type: bool

Modifiers: transient

Override whether to fully stream even if texture hasn't been rendered.

[edit] bHasBeenLoadedFromPersistentArchive

Type: bool

Modifiers: transient, const

Whether the texture has been loaded from a persistent archive. We keep track of this in order to not stream textures that are being re-imported over as they will have a linker but won't have been serialized from disk and are therefore not streamable.

[edit] bHasCancelationPending

Type: bool

Modifiers: transient, const

Whether the current texture mip change request is pending cancelation.

[edit] bIsStreamable

Type: bool

Modifiers: transient, const

Whether the texture is currently streamable or not.

[edit] FirstResourceMemMip

Type: int

Modifiers: private, const, native, transient

keep track of first mip level used for ResourceMem creation

[edit] ForceMipLevelsToBeResidentTimestamp

Type: float

Modifiers: private, transient

WorldInfo timestamp that tells the streamer to force all miplevels to be resident up until that time.

[edit] Format

Type: Texture.EPixelFormat

Modifiers: const

The format of the texture data.

[edit] Mips

Type: Object.IndirectArray_Mirror{TIndirectArray<FTexture2DMipMap>}

Modifiers: native, const

The texture's mip-map data.

[edit] MipTailBaseIdx

Type: int

Modifiers: const

Keep track of the first mip level stored in the packed miptail. it's set to highest mip level if no there's no packed miptail

[edit] OriginalSizeX

Type: int

Modifiers: const

The original width of the texture source art we imported from.

[edit] OriginalSizeY

Type: int

Modifiers: const

The original height of the texture source art we imported from.

[edit] PendingMipChangeRequestStatus

Type: Object.ThreadSafeCounter{mutable FThreadSafeCounter}

Modifiers: native, transient, const

Thread safe counter indicating status of mip change request. The below defines are mirrored in UnTex.h.

>= 3 == TEXTURE_STATUS_REQUEST_IN_FLIGHT - a request has been kicked off and is in flight == 2 == TEXTURE_READY_FOR_FINALIZATION - initial request has completed and finalization needs to be kicked off == 1 == TEXTURE_FINALIZATION_IN_PROGRESS - finalization has been kicked off and is in progress == 0 == TEXTURE_READY_FOR_REQUESTS - there are no pending requests/ all requests have been fulfilled == -1 == TEXTURE_PENDING_INITIALIZATION - the renderer hasn't created the resource yet

[edit] RequestedMips

Type: int

Modifiers: transient, const

Number of miplevels the texture should have resident.

[edit] ResidentMips

Type: int

Modifiers: transient, const

Number of miplevels currently resident.

[edit] ResourceMem

Type: pointer{FTexture2DResourceMem}

Modifiers: private, const, native, transient

memory used for directly loading bulk mip data

[edit] SizeX

Type: int

Modifiers: const

The width of the texture.

[edit] SizeY

Type: int

Modifiers: const

The height of the texture.

[edit] StreamableTexturesLink

Type: TextureLinkedListMirror{TLinkedList<UTexture2D*>}

Modifiers: private, native, const, duplicatetransient, noimport

This texture's link in the global streamable texture list.

[edit] TextureFileCacheGuid

Type: Object.Guid

Modifiers: native, const

ID generated whenever the texture is changed so that its bulk data can be updated in the TextureFileCache during cook

[edit] TextureFileCacheName

Type: name

Name of texture file cache texture mips are stored in, NAME_None if it is not part of one.

[edit] Timer

Type: float

Modifiers: private, const, native, transient

Used for various timing measurements, e.g. streaming latency.

[edit] Structs

[edit] Texture2DMipMap

Modifiers: native

A mip-map of the texture.

Object.UntypedBulkData_Mirror{FTextureMipBulkData} Data 

int SizeX 

int SizeY 

[edit] TextureLinkedListMirror

Mirror helper structure for linked list of texture objects. The linked list should NOT be traversed by the garbage collector, which is why Element is declared as a pointer.

pointer Element 

pointer Next 

pointer PrevLink 

[edit] Functions

[edit] Static native functions

[edit] Create

creates and initializes a new Texture2D with the requested settings

[edit] Native functions

[edit] SetForceMipLevelsToBeResident

Tells the streaming system that it should force all mip-levels to be resident for a number of seconds.
