xCutsceneData

• If ChunkSize and FileOffset are 0, an external MODL is used within the HOP.
• Every model has padding - 0x00 bytes at the end, 2048 byte alignment.

Offset	Type	Variable	Description
0x00	uint	DataType	1 = MODL 6 = JDTM (JDeltaModel) (Not present in Scooby)
0x04	AssetID	AssetID	AssetID of model.
0x08	uint	ChunkSize	Size of model.
0x0C	uint	FileOffset	Offset to model.

xCutsceneTime

Offset	Type	Variable	Description
0x00	uint	TimeChunkOffs	Offset to TimeChunk

Visibility

Offset	Type	Variable	Description
0x00	uint	Visibility

xCutsceneBreak

Offset	Type	Variable	Description
0x00	float	Time
0x04	int	Index

Padding

Padding - 0x00 bytes, 2048 byte alignment.

TimeChunk

Each timechunk has a 0x10 byte header:

Offset	Type	Variable	Description
0x00	float	StartTime
0x04	float	EndTime
0x08	uint	NumData	Number of entries.
0x0C	uint	ChunkIndex	TimeChunk index.

xCutsceneData

Each entry has this 0x10 byte header:
