Imagine that I have a shape that has some tight, intricate curves. Just for
simplicity, something in the shape of the letter "S". What I need to do is have
a fill start from one end of the S and follow that shape to the end, so the new
color grows along the path, oriented to the shape of the path. In essence, the
shape will "grow" from nothingness into its full form. It's very similar to
using sweep nurbs in Cinema 4D, if that helps.
I tried using a mask but I don't know how to make it "follow" the curves of
the S. Can somebody please show me the best way to do that? Tutorial? Is it
a script thing?
Thank you.

Hello there,

How bout just animating it frame by frame. Draw your S shape with the Pen
tool. After frame 1 in the timeline, select about 14 empty frames and hit F6
to turn them into keyframes. Start from frame 1 and use the Eraser tool to
erase most of the stroke except the bit and the beginning. Carry on with all
the frames revealing more of the stroke as you go. You can use the comma and
period keys on your keyboard to move back and forth along the timeline frames.

Hope that helps
