[union]

union { ... } FAllocatedVTDescription

AdaptiveLevelBias

uint8 FAllocatedVTDescription::AdaptiveLevelBias = 0u

bPrivateSpace

uint8 FAllocatedVTDescription::bPrivateSpace

Should the AllocatedVT create its own dedicated page table allocation? Can be useful to control total allocation. The system only supports a limited number of unique page tables, so this must be used carefully

bShareDuplicateLayers

uint8 FAllocatedVTDescription::bShareDuplicateLayers

If the AllocatedVT has the same producer mapped to multiple layers, should those be merged into a single page table layer? This can make for more efficient page tables when enabled, but certain code may make assumption that number of layers specified when allocating VT exactly matches the resulting page page

Dimensions

uint8 FAllocatedVTDescription::Dimensions = 0u

ForceSpaceID

uint8 FAllocatedVTDescription::ForceSpaceID = 0xff

IndirectionTextureSize

uint32 FAllocatedVTDescription::IndirectionTextureSize = 0u

MaxSpaceSize

uint32 FAllocatedVTDescription::MaxSpaceSize = 0u

Name

ProducerHandle

FVirtualTextureProducerHandle FAllocatedVTDescription::ProducerHandle[VIRTUALTEXTURE_SPACE_MAXLAYERS]

Producer for each texture layer.

ProducerLayerIndex

uint8 FAllocatedVTDescription::ProducerLayerIndex[VIRTUALTEXTURE_SPACE_MAXLAYERS] = { 0u }

Local layer inside producer for each texture layer.

TileBorderSize
