Feather a shape layer

[bjgough]

This has to be possible. Right?

I am trying to create a mask for an animated layer. The animated layer is increasing in scale while changing its position to move off the bottom of the composition. I can create a perfect MASK for that layer, but it moves with the layer. If I could lock the mask, that would be great.

So, instead, I am trying to create a TRACK MATTE. The problem is, I can create the right ellipse to MATTE the animating layer underneath. But, I can't soften it's edges. I've tried adding a glow effect, but it's not enough.

I know this is simple. I've spent 45 minutes trying to do it myself and looking for similar questions/posts... but nothing has helped.

I've just come across this problem and found this:

Basically just apply a drop shadow (effect) on your track matte, then:

- check the "shadow only" checkbox

- distance: 0

- opacity: 100

and play with the softness.

This is too funny!  I didnt read down to the bottom of this thread and after mucking around a bit I landed on "adding a drop shadow" to the shape!  (I was trying to have the 'sun' rise from a misty bog and the hard edge of the track matte was not working).  The drop shadow works well enough with the opacity and softness way up.  I'll add a link to the final result when I finish it.  Finally a decent work-around.
