How to mask where I don't want to see the layer and its animation

[#1]

Hi,

I've been getting some really great help but I want to only see the 'little lines' layers as they pass over the object of which they are in front.  There is a background layer but I've turned if off while I try to find the solution.  I've grouped the layers as you will see - but how do I mask/hide them unless in front of the shape.  I think it may be about black over the whole layer and then rub back to white to show the parts that are to be seen.  Hope this makes sense.  All help is appreciated.

Thank you. I have thought realistically about AE as an option.

Do you mean how to hide any part which goes beyond shape bounds? If that is the case do the fllowing:

• Put all shapes in layer group.
• Create selection from transparency by Ctrl + clicking on layer thumbnail of layer with shape.
• Create group mask from selection.
• Everything you add to that group will be hidden beyond shape/mask bundaries.

Thanks Bojan, that seems like a promising option.  Will try it ut now.
