Ok, so when I go to take the shots and copy the cfg files (using notepad+++) a message shows up tellling me that a program overwrote something in the file (apparently, the direct = on that I edited the first time using notepad) and ask me if I want to restore, the direct was "on" but I press restore anyway to see what happens, the direct goes back to off so I put it back to "on" and save again. I open the cfg again but the message doesn't pop up again.
I'm launching the game and.. surprise! the battle models were working perfectly. It seems that when I edited the cfg file something strange happened and did not save correctly.
Thanks for the help and sorry for the problems!
