Syntax

class FUsdLevelSequenceHelper

Remarks

Builds and maintains the level sequence and subsequences for a Usd Stage

Constructors

	Type	Name	Description
		FUsdLevelSequenceHelper ()
		FUsdLevelSequenceHelper ( const FUsdLevelSequenceHelper& Other )	Copy semantics are there for convenience only. Copied FUsdLevelSequenceHelper are empty and require a call to Init().
		FUsdLevelSequenceHelper ( FUsdLevelSequenceHelper&& Other )
