Man, I can't believe this. I'm sure I speak for everyone you've ever helped complete a project, that you are just such a huge disappointment.
LOL! Yes, that's probably true.
I tried writing my own model viewer and couldn't get any of the rotations to work. I can tell you how I
think limits work, but it'll be just an educated guess.
Remember that post that Borde made linking the files to actual limits? Those each have up to 16 animations; 8 for a player and 8 for their weapon. I don't know the logic behind this, but I can only assume it's meant for weapons to be thrown even though this never actually happens. But from what the AB scripts for the limits look like, the animations on that get "appended" to the current character models' animations (starting at index 2C) and they are executed in that way. What happens to the weapons I have no idea, but they are actually disconnected from the character model at that point and considered their own model.
