Animate Mode Sample Project
This
project demonstrates how to use animate mode to modify existing animation
channels. The project contains a simple animated
camera. Press play to watch
how the
camera moves.
The
Animate Mode Button is the last button on the Manipulator toolbar. You may
have to
reset this toolbar to make it show up.
Animate mode is on by default,
so the
software comes up wit this button depressed.
Each keyframe on the camera
was
created with animate mode on. When
animate mode is on one key is created at
the
current frame. Turning animate mode off signals the software to not add any
new
keys, rather alter all existing keys to create the desired change. This is
handy
for positioning lights at time 5:12, but you don't want the light to
animate
from where it was positioned at time 0:00 to where you moved it at frame
5:12.
Rather you want to modify the 0:00 keyframe so that the light just moves
over at
all frames from 0:00 to 5:12. It does
this by altering the keyframe
that
was already set at 0:00.
To try
this feature on the sample data, stop playing and change the frame to
0:00:20. If your timeline window is open, and the
camera is selected, note that
there
are no keyframes at this frame. Note
that the camera is not at the
origin,
but is close. Translate the camera to
the origin. Notice that a
keyframe
was created in the timeline at 0:00:20.
The camera now ramps up to the
origin
at frame 0:00:20. This is what animate
mode always does. But, we want
to take
the entire curve of soft motion and move it up so that all keyframes
are
higher and the camera passes through the origin at frame 0:00:20. Undo the
last
change or delete the keyframe at 0:00:20 by grouping the points in the
timeline
and pressing delete, or just reload the project. Now turn Animate mode
off,
implying we do not want to add new animation keys. Now go to frame 0:00:20
and
translate the camera to the origin again.
This time no keys are added to
the
camera. Instead all existing keys are
moved in the direction your mouse
specified. In fact if you watch the channel window
while you drag the mouse,
you
will see that all of the keyframes are moving around. Frame 0:00:20 looks
just as
we wish, yet AM didn't even add a keyframe at 0:00:20. Play back the
motion
and check it out.
This
concept works on rotates too. Notice
how the camera wiggles back and forth
but
points primarily to the left. Go to
frame 0:00:20 again, and make sure
animate
mode is off. Rotate the camera to point
straight up. Now play back the
animation,
and note that the camera still rocks back and forth softly, but it is
aiming
primarily up now, and it is exactly up at frame 0:00:20 where we set it.
Again
there are no new keys at 0:00:20, it just changed all the other keys to
rotate
it straight up at 0:00:20.
