Syntax

void InitializeFromExistingAndPrune
(
    const FAssetRegistryState & ExistingState,
    const TSet< FName > & RequiredPackages,
    const TSet< FName > & RemovePackages,
    const TSet< int32 > ChunksToKeep,
    const FAssetRegistrySerializationOptions & Options
)

Remarks

Initializes a cache from an existing using a set of filters. This is more efficient than calling InitalizeFromExisting and then PruneAssetData.

Parameters

Parameter	Description
ExistingState	State to use initialize from
RequiredPackages	If set, only these packages will be maintained. If empty it will keep all unless filtered by other parameters
RemovePackages	These packages will be removed from the current set
ChunksToKeep	The list of chunks that are allowed to remain. Any assets in other chunks are pruned. If empty, all assets are kept regardless of chunk
Options	Serialization options to read filter info from
