Hi again
Trying to make this clearer.
What I am looking to do is create a p/shop file with multiple masks, import the file into AE, then work with these masks so that they have a CUMULATIVE effect on the background video/image (ie, one image masking, then second is added to this mask, and so on …)
I can achieve this cumulative effect by creating simple mask shapes in AE itself. These masks all appear underneath (or within) the image layer (ie when I twirl down the image layer).
Here is an example of relationship between masks and their image layer: https://www.skellis.net/Images/fromAE.jpg
However, eventually I want to develop complex mask shapes (in photoshop) and do the same thing.
When I try and do this the masks (from photoshop) are all placed in their own layers (and not as a part of the background image layer as above).
Here is example: https://www.skellis.net/Images/fromPSD.jpg
However, in this latter example the masks (if more than one is visible) cancel the other masks out – and I end up with simple a white screen! (hence only one ‘mask layer’ being visible in this second example).
What am I doing wrong or missing?
I have tried to copy these layers (imported from photoshop) into an image/video layer in AE – but they stubbornly refuse to go there (and just create new layers).
I am sure there is just small part of either a) creating masks in p/shop for use in AE, or b) how to generate the ‘correct’ relationship between the masks and the background image in AE – that I am missing.
Help ….
Cheers
Simon
