Mask tool plugin for AE

[Indie767]

I am looking for a plugin that 1) can animate the shape of a mask, in my case from an ellipse to a custom shape, and 2) have multiple mask opacity controls. 

I googled for a plug in but could not find one. 

Does anyone know of a tool to achieve this?

Take a look at Mask Transformer at AESccripts.com.

You can also use the Create Nulls from Paths.jsx script to attach nulls to vertices. Find it at the bottom of the Window menu. I do that all the time.  

Create Nulls From Paths extended is free and gives you much more control. That is my go-to mask animation tool.

Thanks, Rick. This looks super helpful.

Do you need a plugin to do this?  If I want to morph a mask shape, after keyframing the mask path when set as an oval, I'll move the timeline then paste in the second mask's path.  If I don't have a path for the custom shape, Auto-trace will create one.
