UE3 doesn't serialize array element types. Element types are inferred from property names via whitelists (STRING_ARRAY_KEYS, NAME_ARRAY_KEYS, INT_ARRAY_KEYS). Unknown array keys default to StructProperty.

Symptom: "Name index out of range" errors when encountering an unknown TArray<FString> or TArray<FName>.

Fix: Add the array's key name to the appropriate whitelist in ue3_properties.py.

Maps also require key/value type inference from the property name. Unknown map keys will raise NotImplementedError.

Some MK11 PSF files cause Oodle v5 DLL segfaults during decompression. This appears to be a DLL compatibility issue. Parsing with skip_bulk=True works around this.

These files have compression flag 221804592 which doesn't map to any known CompressionType enum value. They may be from a different engine version or use a format not yet supported.

NRSAudioBank, NRSAudioEvent, and NRSAudioStreamingSource exports parse successfully but have no handler — the raw data is likely RIFF/WAV audio that needs a dedicated handler.

The following export types have no handler and are extracted as raw binary blobs:

• SkeletalMesh — 3D mesh data
• MaterialInstanceConstant — Material parameters
• MKClothSet — Cloth simulation data
• AnimSequence — Animation data
• Various script/package types
