Description
When auto evaluating clip planes, determines whether 16bit depth scaling should be used.16bit scaling is advantageous for any depth downscaling that occurs (e.g. HZB downscaling uses 16 bit textures instead of 32).This feature will calculate the maximum depth scale needed based on the Unreal Unit (cm by default) to Pixel ratio.It assumes that we don't need 32bit depth range for smaller scenes, because most actors will be within a reasonable visible frustumHowever it does still scale up to a maximum of UE_OLD_WORLD_MAX which is the typical full range of the depth buffer, so larger scenes still work too.
