How does Rise handle Storyline blocks with large file sizes

Hi Joe, thanks for your quick reply. 

I've looked at the article you linked and it has great info about how Storyline loads content, thank you. Because it's a branched interaction and I'm trying to stop the unnecessary preloading of videos that the learner might never play, it looks like if I put them all on separate slides, instead of separate layers of the one slide, that will limit Storyline to only preloading three of them.

Thanks, Rowan
