What game engine was Blue Dragon made in?

[InfernoZotza]

Hello, I've been trying recently to rip models from the Xbox 360 JRPG Blue Dragon but have run into an issue with not knowing what engine it was made in so I can view the assets. I know that Lost Odyssey (the next game from Mistwalker's library) was created with the Unreal 3 engine, but after digging for a while on Blue Dragon I am finding nothing. Most reports are vague, only saying "the game engine." Not much of a help, 2005 IGN, are you?

Nevertheless, if anyone can help me with this it would be much appreciated.
