UAssetManager::GetPakChunkIdToStringMapping

function Engine Since unknown

#include "Engine/AssetManager.h"

Access: public Specifiers: virtual

Description

Allows the asset manager to override a pak chunk id with a string name instead of an integer, used at cook time to name the generated pak chunk files.

Caveats & Gotchas

• The base implementation is a no-op ({}) — you must override it in a UAssetManager subclass to supply overrides, otherwise pak chunk file names use plain numeric ids.
• A second overload taking a PlatformName lets you override per-platform; the cooker prefers that overload when available.
• Override strings must be alphanumeric with no spaces, or pak/chunk generation can fail.
