UAssetManager::OnAssetRegistryAvailableAfterInitialization

function Engine Since 4.24

#include "Engine/AssetManager.h"

Access: public Specifiers: virtual

Description

Called when a new asset registry (for example a plugin or DLC registry) becomes available after the engine has already initialized. Returns true if new data was loaded and merged into the master asset registry.

Caveats & Gotchas

• InName must exactly match whatever GetUniqueAssetRegistryName returns for that source, or the callback won't be matched to the correct registry.
• Fires for registries that arrive after initial startup (e.g. mounted plugins, downloaded content) — registries already present at boot go through the normal startup scan instead and never hit this path.
