did you just say... FF8 models?
Indeed. I've got all the monster models that could be implemented into FF7, but haven't had a lot of time to look around and try to find a way to export them to a usable format. I have a viewer for them and that will hopefully use directx. I tried Rinoa but it seems you don't have it set up to read the battle models
EDIT
I did find a post by Qhimm from 2004 where he clearly figured out the battle format and had the models in 3DSMax. Mirex' Biturn can open them (though not correctly)and convert them, but I can't get blender to work properly so I'm unsure if they are exported correctly
EDIT2
The link for enemies and their updated counterparts
http://www.megaupload.com/?d=Y81C4FNVThere are some that are still missing, but I'd say I'm 90% done. The other 10 will come from Koral implementing the few missing Crisis Core enemies into Rinoa, and me going back through the FFVIII and FFX enemies to double check if any can be swapped with some of the more obscure FFVII enemies. I'll also need to run through Dissidia.
Note: the ones highlighted in red are VERY debatable. Since everyone and their mother already has the KH models, I don't see any reason to list them
