Masking question

[LEFT]hi quick question…

I have several pngs of PSbrushes saved, which are leaves and vines and i want them to appear as if being revealed by a cloak or something, you know? Similar to lines being drawn, a kind of animated fill

heres a video with the desired effect, 00:23 into it :slight_smile:

I just dont know how to do it, any ideas?

Thanks
