I'm doing something fundementally wrong here, and I can't figure it out. This started with IK Joints [See 'IK Jointd worse than Bones, and why?] I decided to build another Vertex Primitive figure and start over. Figure_02 is the yellow one. When the torso and one whole leg was done, I discovered that I had left off working on Figure_01 [purple] last night and the scrubber was still at 4 sec. I tried to move it and the key frame for Fig._01 back to zero. The bottom image is what happened. There were no links, no constraints and no IK on anything. I restored the time settings and thought: "OK, I'll start the animation at 4 sec." I finished the other leg, and linked the parts. No IK, no constraints. I moved the legs/torso forward 2 sec. and pulled the legs into the 'crossover' position. Got new keyframes. Then moved the scrubber 2 frames backwards. You'll see the figure flying apart in the Inset. In another frame, everything is gone. When I did the 'Spooky' tutorial in the manual, I dragged him all over the stage, waggeled his arms, rotated his head...all that with Bones and IK. And his multiple parts stayed together throughout a 12 sec. animation. Since then, every visit to the sequencer [w/ multiple parts] has been a disaster. Any thoughts?
