I have fairly simple Motion project, where the Son, Moon and some planets appear above the speakers head, then he throws them off screen. I used the Motion built in Sun Emitter as the Sun, and did a scale animation with an explosion added over the top, I then want to move the sun and Jupiter off the screen to the left. (Other planets will transform off to the right) The sun is in it's own group, but then that group and Jupiter are combined into a group. When I animate the top level group, moving it off to the left, Jupiter goes, but the sun won't budge. If I try to move emitter by manipulating the X position of the emitter it moves, but once I start key framing it (the sun emitter) it won't move. All groups are in 3D mode. What am I doing wrong?
