They're definitly the exported caracters that are processed by the xmls, think theres a bit more to it than simply adding weapons, theres wip/base meshs in the mounts folder as well, geometry seems to be the same but the ingame file is considerably smaller than the base one, havent looked at them other than that though. Dont think we'll be able to replicate the method CA used to make the models anyways.

As for the booleans, I changed the 03 byte to 00 then tested that, then re-wrote most of the values with 00's then tested that, finally I deleted from the 2 byte num_vertex to the last byte of the third data stream (inclusive) and tested that. I also edited the texture on the model in question so I'd be sure the game was using the edited files.
