well then, one way is too look at it like this;
the field animations are the ones at the END of the character data and is before the next guy's. EG: cloud's are aafe, aaff and aaga, tifa's are the next three, but, some models have more than three, so DON'T quote me and say I said the model animations are every three, which they always aren't. bhff (cloud with sword) for example, have the mental attack animations, (sorry for the spoilers for anyone who didn't get that far into the game) and I hope this cleared this up for you.
