Wow. Bold statement. Very bold statement.
I hardly see how you can see that the animation in question is realistic, okay, hes looking at his gun while reloading, cute, anyway then he follows the wall, and suddenly he stops, as if by a magic force, and this magic force, jerks him back 20 centimetres.. Look closely at that last part, maybe its because of the framerate of that gif not showing everything, but it looks like hes getting jerked back 20 cm on the end of the wall, before he leans out
I'll tell you what, how about tomorrow, i will boot up a few games and show you some examples of just as good reloading animations.
Neat but if you read that, it doesn't say 3000 animations and 12 layers, it says hundreds of animations can be layered on top of one another, that probably means that not all of the 3000 animations can be layered (which makes sense, because a lot of the animations simply wouldn't be possible to combine. (If your climbing something, thats an animation that cannot be combined with much).
Also, you do realize its not nearly impressive as it sounds right? A lot of the animations are small stuff like, having the character smile or not. I'm really not sure if I would be so convinced that this system would be much better than just mo-capping 10,000 animations of Altair like in assassins creed. Neither is really based on physics, its just scripting, so it will still be flawed from time to time with floating and what not.
