UAssetManager::GetPakStringToChunkIdMapping

function Engine Since unknown

#include "Engine/AssetManager.h"

Access: public

Description

Helper to get the chunk id based on the string override for a pak chunk, the inverse of GetPakChunkIdToStringMapping.

Caveats & Gotchas

• Internally calls GetPakChunkIdToStringMapping and inverts the result, so it only returns useful data if your UAssetManager subclass overrides that function.
• If multiple chunk ids map to the same override string, only one survives in the resulting map since duplicate keys are silently overwritten.

Signature

TMap<FString, int32> StringToChunkId;
UAssetManager::Get().GetPakStringToChunkIdMapping(StringToChunkId);
