Star Stable ripping models

[melonya]

I'm trying to rip the models. No one was able to extract this game's models, at least with their rigs intact. 
There's no information on the engine being used, 'PXStudioRunTimeMMO', and the file formats can't be imported into the programs I'm using at the moment. 
.pme, .pte, and so on. Cant use the ninja ripper either. Can anyone do a tutorial or give me instructions thanks alot.
