Manualy adding anims?

[Modeler]

I just got into real modeling, and i opened up an mdl file in notepad, and i noticed this line:

}
Anim "Stand - 1" {
Interval { 3333, 6667 },
MinimumExtent { -172.896, -162.786, -43.2397 },
MaximumExtent { 151.846, 161.956, 127.762 },
BoundsRadius 232.077,
}

It makes absolutely no sents how this works, but i editied it a bit, and it came out very choppy. So im wondering, could you add in your own animation, just editing the text file? Or is there something im not seeing here?

Well, that's just the timings

To make your own animation, you need to go down. To the bones

And meddle with the various settings there

But yes, it IS possible to make an animation in pure MDL. Just hard
