DumpToConsole

Public function Virtual Const

GetLocalMipBias

(
    uint8 vLevel,
    uint32 vAddress
)

Gives a localized mip bias for the given local vAddress.

ProducePageData

    const FVirtualTextureProducerHandle...,
    uint8 LayerMask,
    uint8 vLevel,
    uint64 vAddress,
    uint64 RequestHandle,
    const FVTProduceTargetLayer* T...
)

Upload page data to the cache, data must have been previously requested, and reported either 'Available' or 'Pending' The system will attempt to call RequestPageData/ProducePageData only once for a given vLevel/vAddress, with all the requested layers set in LayerMask, this is important for certain types of procedural producers that may generate multiple layers of VT data at the same time It's valid to produce 'Pending' page data, but in this case ProducePageData may block until data is ready Only called from render thread

Public function

RequestPageData

(
    const FVirtualTextureProducerHandle...,
    uint8 LayerMask,
    uint8 vLevel,
    uint64 vAddress,
    EVTRequestPagePriority Priority
)

Makes a request for the given page data.
