I have a simple masked ball shaped object which is animated a long a path. When I import in a new PSD I want to replace and drop onto the ball shaped object, it's original mask shape that I want to retain assumes a different, larger mask. My question is- how do I keep that original mask locked? I've locked it within the Comp dialogue box, but that does not help. I've also tried importing the new image with and without an alpha, but get the same results. Thank you for any help
The vertex information is based on layer size. You've got two options.
And a third alternative: Copy the mask and keyframes to the clipboard, replace the footage, paste back. Works many times, if the layer anchor point is in the same relative position.
