With the newly created keyframe still
selected, enter
48
for Frame and
84.722
mm
for Value. (From frame 0 to frame 48,
the texture's position along the X axis will
change by +84.722 mm.)
•
Pre Behavior and Post Behavior should
both be set to
Linear
, so rate of change
defined by the keys at frame 0 and frame 48
continues
indefinitely
both
before
and
after
our two
keyframes.
•
Right-click on the chan-
nel you have been working
on, and choose
Copy
. Then,
right-click on the other two
channels, in turn, and choose
Paste

With one of the Position channels
active (it doesn't matter which one, as
we'll be copying and pasting it to all the
others), activate the
Add Keys
button
and click somewhere near frame 50.
(My click just happened to be on frame
48; precision isn't really important
right now.)
Figure 17-17: A render of what we've done now shows our shaft of
light catching some vaporous clouds. (The scene that has all this
work already done for you can be found at Scenes\Chapter_17\
Glow_02_F.lws.)
