Showing onion skins in the swf is what i mean. i assume its some sort of actionscript
I’m guessing duplicate the movieclip and then let its alpha value decrease quickly.
i was thinking it be easier, like a actionscript shortcut since doing it by hand would get kinda tedious :\
there is an actionscript code called duplicateMovieClip
you could use it together with a for look if you want to duplicate it several times
Add the extra line for an onionskin effect.
