- Forms Editor
-
-
- I was working in the forms editor on an object, and loaded it
- into the detail editor for modification. However, I can't seem to be
- able to get it back into the forms editor! Help!
-
- Simply put, you cannot load objects saved from the detail editor
- back into the forms editor. The reason is the forms editor requires a
- specified object structure which the detail does not. Thus, saving an
- object in the detail editor loses that information.
-
- When you work with the forms editor is recommended that you keep
- a spare copy of the FORMS OBJECT saved separately from any detail object.
- In this way you can then go back and make modifications in the forms
- editor.
-
-
- Cycle Editor
-
-
- I made this really great animation sequence in the cycle editor, but when
- I set it up in the stage/action editors, the motion of the overall object
- isn't there!
-
- When using the cycle editor, Imagine only remembers changes in
- size, position, and so on in relation to the main parent. Thus, if you
- make a change to the parent object, it gets forgotten. What this means
- is if you make a nifty robot jumping cycle, and make it in the cycle
- editor so the robot actually move up etc... all that will be remembered
- is the changes to the legs, arms and anything OFF of the PARENT. The
- overall rotations and movements to the main object will be gone.
-
- Two solutions exist. One is to simply make those changes in the
- stage editor each time you need to. The second is to group a plain axis
- before you start to your object. (ie: Make the parent have a Null
- link). Then, you can rotate everything by rotating the main child
- grouped right under this null axis. This way you aren't moving the
- "parent", and everything will be remembered.
-
-
- Animation, Stage Editor and Action Editor
-
-
- Even though I move an Object/Camera/Light to a new
- POSITION/ALIGNMENT/SIZE in the STAGE editor, Imagine seems to 'forget'
- what I did!
-
- All objects must have timeliness split wherever there is a change in
- position, alignment or size. If you do not set this up, Imagine will
- forget the changes no matter what.
-
- Rather than going back and forth to the ACTION editor and adding ,
- you can have Imagine automatically create the properly so everything
- tweens as normal. There are the "Position Bar", "Alignment Bar" and
- "Size Bar" commands under the OBJECT menu in the STAGE editor.
-
- So, if you have just gone to a frame and are making a new POSITION,
- ALIGNMENT or SIZE for an object (or camera or light) to tween to, press
- RIGHT AMIGA and 7/8/9 respectively. Or use the respective bar commands
- >from the OBJECT menu. This will extend or put a 'split' in the timeline
- for you (you can check this in the ACTION editor). Also, don't forget to
- "Save Changes"if you want to keep the motion!
-
-
-
- How do I use the Grow Effect?
-
- To use the grow effect, create an object in the DETAIL editor
- that you wish to have 'extrude' over time. Create a spline path as
- normal in the detail editor. This will be the path the object extrudes
- along during the animation.
-
- GROUP (not join) the object with the PATH AS THE PARENT. If you do
- not make the path the parent, it will not work. To do this, select the
- path, then hold shift and select the object, then select group. Save
- your GROUP for loading in the animation.
-
- Finally, add the effect in the ACTION editor for the grouped object.
-
-
-
- How do I use the Tumble Effect?
-
- The tumble effect is used to tumble 1 or more objects during an
- animation. To tumble an object, create your object or objects in the
- DETAIL editor. Still in the detail editor add an axis.
-
- Group (not join) the AXIS to all the objects you want to tumble
- with the AXIS AS THE PARENT. Then load the GROUP into the STAGE/ACTION
- editor and add the effect as normal.
-
- NOTE: The reason for the null object (axis) as parent is that
- Imagine does not TUMBLE the PARENT, just the children.
-
-
-
- How do you get something to roll (at the right speed!) while following a
- path?
-
- Getting an object to spin (like a plane doing a barrel roll) is
- easy- you align to path, then set Y rotation to be from 0 to 360 and it
- will do a complete spin. This is not in the right direction for a
- rolling ball, though. [Annoying feature- you can't say from 0 to 720 for
- two spins, or 0 to 3600 for ten.] To get it to roll I created a second
- path, which was basically a larger copy of the first, so the first path
- was just inside of the second path. I had an axis (a track) follow this
- new, outside path, then used "align to object" to make the sphere point
- to the axis.
-
- Thus, as the ball moved along its path, one end (the positive Y
- axis direction) was always pointed at right angles to the direction of
- motion. Is this clear? Now using the "initial Y angle" and "final Y
- angle" I set them to 0 and 360 and it rotated as it rolled. As a special
- effect, I raised the "track path" a little in the Z direction so the
- sphere looks a little bit like a top rolling around, since the spin axis
- was not horizontal any more.
-
- An alternative would be to make a cycle object, rolling around
- the X axis. This is equally valid, but I did it this way first.
-
-
-
- When I move a tracked Camera in the STAGE editor, it doesn't realign and
- draw the Perspective view correctly!
-
- If you have Imagine 2.0 or higher, press RIGHT AMIGA and the K key
- together, or select "Camera (Re)track" from the OBJECT menu. This will
- make the camera repoint to the track from the new position and will
- redraw the perspective view.
-
- If you have an older version of Imagine (or if you just want to)
- you can press RIGHT AMIGA and the C key or select "Goto" from the FRAME
- menu. Go to the current frame you are already on which will cause
- imagine to redraw everything.
-
-
-
- I have found that after creating a scene in the Stage editor, and then
- deciding that I want an animation and adjusting the highest frame count,
- my scene gets mangled in the first frame. Why?
-
- Well, it seems to me that this will happen if you don't split
- your channel bar from the first frame (where you want stuff to be
- exactly) to the second frame. I usually setup my scenes so that I have
- the first frame all set as it should be and then I do my transformation
- >from frames 2-whatever. In this way, the first frame is ALWAYS where
- it's suppose to be no matter what changes I make in the remaining
- animation. If you look at your channel it should have a break between
- frames 1 and 2 and then be continuous (if that's the way your animation
- works out) from 2 on.
