APub: How Can I edit a Mask?

[Amdival]

I've created a mask by dragging a placed photo inside of a rectangle in the layers panel.

How can I edit the shape of the mask now? I can easily edit the size, scale, rotation of the masked photo, but how do I edit the mask?

There's no obvious/intuitive way of editing the mask. How do I rotate it independent of the photo? How do I select individual nodes to move? If the mask is a rectangle that I need to be wider, how do I edit it to be wider?

Select the rectangle in the Layers panel and you should be able to do what you want. Use the move tool, if you want to use nodes you'll have to first convert the rectangle to a Curve.

Awesome, thanks! Convert to curve was key!

This was driving me mad! To get around it I was moving the photo out of the mask, editing the mask, then moving the photo back inside the mask.
