Syntax
UPROPERTY (EditAnywhere, Category=Random)
uint8 bRandomizeWithoutReplacement: 1
Remarks
Determines whether or not this SoundNodeRandom should randomize with or without replacement.
WithoutReplacement means that only nodes left will be valid for selection. So with that, you are guarenteed to have only one occurrence of the sound played until all of the other sounds in the set have all been played.
WithReplacement means that a node will be chosen and then placed back into the set. So one could play the same sound over and over if the probabilities don't go your way :-)
