Hi all,

I need to produce an animation in which the figures are grasping objects. I worked really hard to get a good looking grasp for one of the figures on one frame. I then unkeyed all the frames between that frame and the final frame, and copied the frame I had just worked on to the final frame. Yet, when I play the animation, Poser interpolates away from the keyed in grasp! I want it to remain fixed for the course of the motion.

What's going on here? There seems to be a flaw in my understanding of keying in the joints. I key in ALL the joints of the hand, including all of the fingers. It will save me a lot of time to figure this out.

Thanks!

Poser uses spline animation by default. That means that every movement will continue in a curved line from every keyframe you set - if your fingers were moving to close, they'll close a little further before trying to get back to what you set next, because it's trying to make that curve.

In the Animation Palette you can set this behaviour differently. Go there, select the body parts you wish to configure, then select the frames for them you want to affect.

Those three icons up there, right after the add and delete keyframe buttons, change the movement behavior. First one is the default spline section - that makes every rotation and position change into a curve. The second one is the linear section - it'll make the frames between your two keyframes in a straight line. Third one is the constant section, it'll keep the rotations and positions the same until you change them in a keyframe - this is the one you want for this.
