UUsdAssetCache3::DeleteUnreferencedAssets

API > API/Plugins > API/Plugins/USDClasses > API/Plugins/USDClasses/UUsdAssetCache3

Description

Deletes all assets that:

• Are currently tracked by the asset cache;
• Are set as deletable;
• Are not used by other UObjects (by external assets, components, undo buffer, Python scripting variables, etc.).
• Have no referencers;
• Have not been saved to disk;

If bShowConfirmation is true, this will fallback to using engine code for deleting the assets, showing a confirmation dialog listing the assets that will be deleted. If false, it will silently try deleting the assets it can.

WARNING: This will clear the undo buffer (i.e. transaction history) and run garbage collection after deleting.
