Oh okay. Thanks, guess I'll do some digging. *equips a shovel and spins it to the fan fare music then places it on his back*
I would suggest looking in the TOOLS forum for 'model conversion' you could roll your own tools my using the
wiki information under FF7. Their are 2 sets of models the chibi style ones are in the field (IE hence field models) these are seperate from the battle models (hence why they look different). Fortunately FF7 used a relatively simple model setup. The complex part is the animation. You need to match the bone count to make the animations to just work without modification.
You don't want to make new animations as I don't believe tools are available for that and the format is non trivial in nature to decode let alone make (uses delta compression and bit packing).
You should look at the tools area to see what model formats / programs the converters were made for before you assume you have one that will work.
For what little I could help you with, you will just need to be patient in doing this, take your time and think things through and you do just fine.
