Public Attributes
Layout
bool	bContinuousUpdate
	Enable continuous update of the virtual texture pages. This round-robin updates already mapped pages and can help fix pages that are mapped before dependent textures are fully streamed in.
bool	bCompressTextures
	Enable storing the virtual texture in GPU supported compression formats. Using uncompressed is only recommended for debugging and quality comparisons.
int	RemoveLowMips
	Number of low mips to cut from the virtual texture. This can reduce peak virtual texture update cost but will also increase the probability of mip shimmering.
bool	bClearTextures
	Enable clear before rendering a page of the virtual texture. Disabling this can be an optimization if you know that the texture will always be fully covered by rendering.
bool	bSinglePhysicalSpace
	Enable page table channel packing. This reduces page table memory and update cost but can reduce the ability to share physical memory with other virtual textures.
bool	bPrivateSpace
	Enable private page table allocation. This can reduce total page table memory allocation but can also reduce the total number of virtual textures supported.
bool	bAdaptive
	Enable sparse adaptive page tables. This supports larger tile counts but adds an indirection cost when sampling the virtual texture. It is recommended only when very large virtual resolutions are necessary.
