- Do you remember the movie Ghostbusters. They used plasma guns that
- effectively were long tentacles that moved as the electrical particles
- traveld down the path. Unless you have a path that can morph, you can not
- achieve this effect. That is to say having multiple objects traveling down
- a path as in the case of the original idea that was brought up about having
- letters follow a path. The easiest way to explain this is to say that a
- static path or spline will always look static if you are having multiple
- objects follow it. If the path can morph while the objects are moving then
- it creates a completely different effect. Another use of this would be to
- have bubbles traveling up from the ocean floor. You wouldn't want a series
- of bubbles all traveling the same exact path so you could save time if the
- path morphed.
-
- I also have desired the ability to make an object conform to path without
- it having to travel it's length as well. This could be good for seaweed
- or tentacles or lot's of different effects.
-
- Going back to the bubble issue, I once made a request for an new Stage
- effect that would cause an object to float like a balloon in a random
- direction but with some control.

- You can get objects to conform to paths in the Stage Editor without having
- them travel the path's length. I've used this quite effectively on several
- spentine-like-creatures. Instead of boning a Dragon-like model, I conformed
- it to a path in the stage editor and morphed the path. The Dragon model bent
- very smoothly conforming to the gracefull curves of the spline. It was fast
- and very serpentine smooth. You can add other elements of motion--like
- expanding bellies--by morphing a deform tool that envelops selective parts of
- the model.

- Stephen,
-
- What I do is create the first Path.iob in the Stage Editor and save it. Then
- I set my object to conform to to that path on frame by frame basic instead of
- one bar across the whole time line. That way the object doesn't travel the
- path, it only conforms to it. Copying and pasting those little bars in the
- Action Editor saves a lot of time.
-
- I then go to the frame where I want the path to morph. I edit the path to
- the shape I want it and save it under the name of Path2.iob. Then you pop
- back into the Action Editor and insert at the appropriate frame Path2.iob in
- the same time line as the original Path1.iob. They're separate objects, but
- they'll morph because they have the same number of control points. When you
- return to the Stage you'll see that your object has conformed to the morph of
- Path1.iob and Path2.iob. You basically work your way through the entire
- animation this way: building new paths; saving them under different names;
- and then inserting them in Path Timeline in the Action Editor.
-
- Later, you can scroll to the key frame of each path and tweak it further.
- Save the path after editing. Refresh the stage frame and your object
- conforms to the new settings. For somethings it's a lot faster than boning
- models.
