Using a vector shape layer to reveal another layer

I am trying to build an animation where a vector shape imported from Illustrator reveals some text (also a vector from AI) as it moves across the stage. I have been using a mask on the text and manually animating it to the movement of the vector shape. The issue is that every time I change the speed of the shape's movement, I have to re keyframe the mask on the text. This seems like a very clumsy way to achieve my desired result.

Is there a way to link/parent a mask in the text layer to the vector shape? I have read that you can turn the vector shape into an AE shape layer, then copy the shape path to the mask in the text layer but I have not been able to get this to work. No matter what I do, the mask will not accept the outline/path of the shape layer.

I have searched extensively and can't find any tutorial/explanation which prompts me to think I'm not searching the right terms.

Hi John

Thanks for your help.

I actually want the vector shape (in this case a plane) to act like a mask and reveal the text (like a mask set to add) as it moves over it so that it remains on screen after the plane has continued (rather than just being visible through the plane shape as with a track matte). I had in mind to extend the size of the mask once the plane has passed through so that the text would remain visible.

Let me know if this is not making sense - I'm not sure I'm explaining it very clearly.

That's a perfect solution. Simple and effective.

Thanks so much - I've been melting my brain for days trying to achieve this and I knew there had to be a simple way to do it but I couldn't seem to stop over-engineering it.

Really appreciate the demo project too - above and beyond the call of duty.

Have a great weekend.
