And each unitart group shares their animations; you could include the pieces of equipment in each unit model, and then only need two animations per piece of equipment per unit group, much easier than making the multiple models for each individual unit. Not to mention the animation would be simple compared to attack animations/it would barely even impact the base unit model. But thats the beauty of it; you could accumulate gear with each animation, without the diffaculty of making animations for each combination of equipment.
Since the part of the model that is the equipment won't go away by simply going into another animation(which I'm assuming is this case, maybe you know this is not the case and you're right here).
...No. Unless I'm MAJORLY misunderstanding you, this is not the case at all.
Animations (as far as I am aware) cannot simply be swapped out at will; it requires changing the artdef of a unit. They also cannot be FIRED at will (not without rather annoying python, at least, which would be FAR too unwieldy for this). Even if you could, you can't freeze an animation; You'd get stuck with bracers appearing, and then disappearing. Finally, you would STILL need dozens of animations, as you can only fire one at a time; You'd need one for bracers, one for the hat, one for boots, one for a chest, one for every other piece of equipment you want to show, and then one for every possible combination of equipment.
