Hi, is anyone able to extract the UFC 3, 4, 5, Octagon or even the arenas 3D model? Been seeing many 3D models of the fighters extracted but no discussion of the octagon or arena.

Thanks.

Upload files or something, without clay you can't make bricks... otherwise they'll close this thread and you'll be left without the square or octagon or arena...

Thanks.

Here's the UFC 3 (would like the higher games but I am not sure how to unpack those) Stage folder I tried to unpack, but to no success. I'm not sure if this is the folder with the Arena or octagon, but if this isn't it I have the other files.

stage.7z

I think i got it. Now it should unpack compressed textures.

	else
		string Name p "%s/%s.%s" BaseFileName ResourceName ResourceType
		log Name ResourceOffset ResourceSize
	endif	
next i

Got something.

So mesh format is something like this. I will try to write noesis script.

Some progress....

Noesis script. If anything went wrong just let me know. Some textures are missing from scene, maybe in another file.
