How did you do it? This seems to cause a lot of problems judging by the number of questions posted.
I'm not really sure which thing helped. First, I set the ease on the path to 100 percent at the frame I wanted to stop the walk cycle. I move forward one frame, set the enforcement to 0%, then the model bone popped back to the placed it was originally. I set it back to 100 percent, hit the Key Bone filter, selected the model bone and made a keyframe. Set the enforcement to 0%, this time it stayed.
Next, I created a new chor action and set it to begin on the first frame after the walk cycle. I made sure the chor action was below the walk action in the PWS. I selected the walk action and moved to the last frame of the walk cycle and hit the Key Model filter, selected Shaggy and copied the keyframe. I selected the new chor action, moved to the next frame, pasted the keyframe, and that seemed to do the trick.
Forgive me if I've left something out, I don't have time to open A:M and try it before work.
That's actually the effect I was going for, but by the time I finally got Shaggy on the floor, I just wanted to render the darn thing and take a look. When it says 6 hours to complete this exercise in TAOA:M, that wasn't an exaggeration. Luckily, I saved a copy of the project at just the point Shaggy setpped off the path and grabbed the doorknob, so Ill be able to pick up from there when I get back to it! Tip: if you have reached a point in a project, chor, model, etc. that you don't want to mess up with tinkering, save it as a different file name and then make the file Read Only. That way you can keep it intact in case you need to go back to that point later.
Thanks for the comments!
