Functions

	Name	Description
TUniquePtr< ...	CreateAccelerationPerBucket_Threaded ( const TConstParticleView< FSpatialA..., uint16 BucketIdx, bool ForceFullBuild )	Chaos creates new acceleration structures per bucket. Factory can change underlying type at runtime as well as number of buckets to AB test.
TUniquePtr< ...	CreateEmptyCollection()	Create an empty acceleration collection with the desired buckets. Chaos enqueues acceleration structure operations per bucket.
uint8	GetActiveBucketsMask()	Mask indicating which bucket is active. Spatial indices in inactive buckets fallback to bucket 0. Bit 0 indicates bucket 0 is active, Bit 1 indicates bucket 1 is active, etc...
bool	IsBucketTimeSliced ( uint16 BucketIdx )	Determines if bucket implements time slicing.
void	Serialize ( TUniquePtr< ISpatialAccelerationCol..., FChaosArchive& Ar )	Serialize the collection in and out.
