[J_F_S]

Hi,
is it possible to preserve overlapping path in Animate for masks as example?
I want this

But Animate creates a path like this

No.

Separate the overlapping parts.

And how should I do that if I want to use it as a mask because I can have only one layer as a mask layer.
And on it it combine everytime all elements to one.

One mask layer, but with many frames in it.

Develop the mask over time.
