Keeping in line with Anthony's comments, here is something else you can try. Say I have a ten frame animation of Poser Dude holding a ball and in frame 7 I want him to drop the ball onto the floor. I load Poser Dude, parent the ball to his hand, and set the frames 1 to 7 and save these to the library as a pose preset. Next I open the animation edit window and select all elements for Poser Dude and do a break frame at frame 7. Then using the hierarchy editor I make Poser Dude invisible except for the ball. I load in a second Poser Dude(2)and apply the pose preset 1-7 to him. I advance to frame 10, select the ball and position it on the floor, and position Poser Dude(2) as I want him to end up at that frame. Now when I run through the frames the ball appears to be Poser Dude(2)'s hand, until I get to frame 8 at which point it will began traveling downward toward the floor [still parented to the now invisible and unchanging Poser Dude(1)]
