Syntax
struct FLODMask
Remarks
Contains LODs to render. Interpretation of LODIndex0 and LODIndex1 depends on flags. By default the two LODs are the ones used in a dithered LOD transition. But they also be interpreted as the start and end of a range where we submit multiple LODs and select/cull on GPU.
