Full Arena Extraction 3d model Question

[Saya007]

Hello guys, I wanted to know if this arena from the video that I have attached is in the original client lineage 2 ? And what is the name of the Arena?

I just search 3d models files, does any one know how to extract full dungeon models by extracting .fbx ? Not extract part by part but full dungeon 3d model extraction tool, I know umodel way of extracting but It takes too much time to go through it piece by piece, maybe there is a way to extract the entire map and locations properly ? If anyone can help me, thank you!
