	Defines how the mip level is calculated for the virtual texture lookup.

	Enable virtual texture feedback. Disabling this can result in the virtual texture not reaching the correct mip level. It should only be used in cases where we don't care about the correct mip level being resident, or some other process is maintaining the correct level.

	Enable sparse adaptive page tables. Note that the bound Virtual Texture should have valid adaptive virtual texture settings for sampling to work correctly.

	Enable page table channel packing. Note that the bound Virtual Texture should have the same setting for sampling to work correctly.

bSinglePhysicalSpace

bool bSinglePhysicalSpace

Enable page table channel packing. Note that the bound Virtual Texture should have the same setting for sampling to work correctly.
