The GetAssetRegistry blueprint node only produces the asset data for the Material class and its subclasses. It completely ignores the asset data for Actor, derived Actor class Blueprints, and the subclasses of the two data types.
Tested in 4.19.2 (CL - 4033788), 4.20.3 (CL - 4369336), 4.21 (CL - 4473816), 4.22 (CL - 4472895)
Expected: The debug messages should be printing the names of the classes and subclasses of ParentBP, Material, and Actor in order at 2 second intervals.
Result: Only the names of the Material class and subclasses are printed from the AssetRegistry
