How can I put a Slide trigger in my scene?

Hi Rebecca,

Can you describe more about what you're trying to do...what you need the slide trigger for? What type of action needs to take place?

Here's a link to a post by Superhero Phil Mayor that describes a bit about the kinds of triggers (there also a link on this page to a book written by Phil, Steve Flowers, and Russ Still).

Why don´t you put an image or arrow pointing to the right and other pointing to the left, then assing each a triguer that will move forward to the next layer or back to the previous one. 

You´ll need to do the same on each one of the layers.  You may want to uncheck the previous and next buttons of your slider to keep users away of changing slider without seeing all the layers.  Hope it helps. 

Hi Rebecca! It looks as if Becky and Aroldo are taking care of you here, so just let us know how those suggestions work for you and if you need anything further.
