Creating a Write-On Effect


Here's what you have been waiting foran animated write-on effect.

1.

Click the Paint brush icon to return to Paint mode.

2.

Make sure that you are in Persist mode for this effect, because you want to animate the stroke over time.

In Persist mode, the paint stroke is active during the entire sequence, as opposed to Frame mode, where the stroke is active only on the current frame.

3.

Write the word Shake in your neatest handwriting, making sure to form the entire word in one continuous stroke.

Your stroke should look something like this:

OK, I write like a slob. So what!

4.

Toggle QuickPaint to Edit mode so that you can see the stroke.

The stroke is now superimposed over the painted letters.

The startPoint and endPoint parameters determine the percentage point at which the stroke starts drawing and the point at which it ends. You can therefore animate a drawn stroke by setting keyframes for the endPoint from 0 to 100 over several frames.

5.

In the Edit Controls subtab, turn on the Keyframe toggle for the endPoint parameter at frame 1.

6.

Set the value to 0.

7.

Go to frame 50 and set the endPoint to a value of 100.

8.

Drag your slider in the Time Bar.

You should see the word Shake animating. Now, make a flipbook to see it moving in real time.

9.

In the Globals tab, set the timeRange to 1-50.

10.

Click the Flipbook icon, play the clip, and close when done.

It is a thing of beauty.
