I hope your head stops throbbing soon. Looks as if mine is just about to start Turn off that lightbulb, it's hell on theeyes L From what I can understand: initValue is the value it loads up with. If there is no k 1, initValue is the value it has. static is the value that 'Restore Figure' resets it to (most CR2 have the same values for both) the k values are the values set for frames, where k 1 is the first frame, k 2 is the second frame, and so on. These frames are offset by the curently selected frame when a pose is loaded, but not, as far as I know, when a CR2 is loaded (i.e., a CR2 can have a full animation pose in it, but will load as if frame 1 was currently selected, while a pose applied will apply the pose as if k 1 were actually k 1+currentFrame-1, if that makes sense. Al of these values defer to limits if limits are on, and forceLimits 1 (or 4, silly as that is, or 2 or 3, anything over 0 and possibly under 0 though I haven't tested if Poser considers -1 to be true), will make limits be on whether the user intends it or not.
