This should be easy enough, I think i’m having a dense day. All i need is a mask that consists of 3 or 4 circles that start off small and eventually overlap and fill the entire screen. One circle is easy enough, but my problem is getting a single tween to create this effect for multiple circles so that the mask works - I’m not too hot on the rules of masks. Thanks in advance.
