I know how to render the animation playing, but can't figure out how to just render a burst only. Is this possible, and if so please advise how I can do it.
Me too. I think this feature could be optimized since I'm guessing a lot of users would prefer to render one single burst like explosions. Also could need an updated tutorial!
(I hope in next ones you also add a voice over, or/and subtitles, or at lease some kind of "click feedback" so we can follow the tutorials easier, anyway good job)
