If you have tried animating in Poser and have had wild over-shoot of body parts after making an adjustment to a Key frame please help me by requesting they fix this issue.

The really great part about this fix is that it is already in Poser and all they have to do is change a couple of Parameter inputs to a function call that makes the Spline Curve. I will show below why it should be easy to fix and that it is already in the Poser Code.

The below image shows what a Spline Curve should look like. Starts Slow speeds up and slows down as it approaches the end point.

Now if I move the end point from frame 29 to frame 30 (or the last frame in a scene) Notice that we no longer have a Spline, but now have a Linear line

It has been recommended that we use a Break Spline to prevent the over-shoot. In theory that is correct, however in practice here is what a Break Spline does to the nice Curve:

Notice that even though the Key Frame is at frame 29 (as in the first picture) we now have a Linear line because the Break Spline point does not see past the Key Frame. However if you were to put the Break Spline on Frame 1 (or any frame) the movement AFTER the Break Spline acts as it should and makes the curve again.

The REASON for this is that Poser requires the First Frame to be a Key Frame for all channels. So in order to get the Nice Curve on the Next Key Frame the logic inside Poser says that the Prior Value for a Key is the SAME as the Current Key. However the Logic says for the Next Key if we are not at the End use the SAME Value for the Next Key, however if there is no next possible frame Poser probably puts in a NULL value which results in a Liner Line as there are not 3 or more points to try to plot through.

The other suggested way to over come the Over-Shoot is to put in another Key Frame one frame apart. This works OK EXCEPT if you make a small change to one of the Planting Keys and FORGET to change it partner, see below:

As you can see above there is massive over-shoot. Poser's recommended way involves YOU the animator to go in a make a massive amount of extra Keys to prevent the over-shoot. This is needless extra work especially if you use the Posing window to move your figure around with as it makes Key Frames for several parts at once, and then you have to go in and change them all afterwards. And if you never use the Graph editor you will have no clue where the problem with your movements are.

So please file a Bug Report to get them to fix this problem.
