Help Ripping Spongebob BFBB/Movie Models.

[teh_supar_hackr]

I've been wanting to rip models from this game for a while now, but each time I try to it ether does'int do anything, rips only the textures. I know the .hip and .hop files that are normally in heavy iron spongebob games are the same models used with Houdini, a 3d modeler, but when I load the files it gives me an error.
