UAssetManager::ExtractChunkIdFromPrimaryAssetId
#include "Engine/AssetManager.h"
Access: public
Specifiers: static
Description
Extracts the chunk index back out of a PrimaryAssetId created by CreatePrimaryAssetIdFromChunkId. Returns INDEX_NONE if the id isn't of PackageChunkType.
Caveats & Gotchas
- • Returns INDEX_NONE for any PrimaryAssetId that isn't PackageChunkType — check the return value before using it as an array index.
- • Only meaningful for ids produced by CreatePrimaryAssetIdFromChunkId; passing an arbitrary primary asset id is a valid no-op, not an error.
