Please see UDN - Case includes project and potential fix from customer. Need to verify that it does not affect
other parts of the volumetric composition. bHasValidSamples is the same check as
bAnyCloudSamplesInFrontOfWater in that scope.
_Vanilla - Shows the issue on the second cube’s top right corner
_Fixed - Shows the same portion of the cube stable - Uses customer’s fix suggestion
