Hello,

I am trying to animate a paint splatter. My idea was to take a graphic of a paint splatter, Auto Trace the layer to create a mask and animate the mask expansion over a few frames. However, adjusting the Mask Expansion levels is having no affect on the mask, neither is the feather properties.

Any idea on what the problem is? I tried searching the forum but found nothing.

Thanks!

It sounds like you may be looking at the layer window and not the comp window. And don't forget to set an initial Mask Shape -- aka Mask Path -- keyframe so the expansion will actually animate.

I am looking at the comp window not the layer window and I have set the mask path but still no results. Any other ideas of why this may not be working?

The only other thing that comes to mind is this: you can't animate this mask on your splatter layer, because it's alpha channeled and nothing's going to grow. You need to paste this mask on a solid, than animate.
