Hi Rustam,
I'm not sure of there is "correct" way of doing this.
In the past I have created twitterwalls and crawls but there I used only one scene and I created textfields for the texts and animation controllers.
I've used two workflows for this. One where I created 5 textfields and 5 animation controllers and I simply cued up the textfields, put in the text and then let it play.
Another workflow was where I created a textfield and a animation controller dynamically and once the animation controller was at the end of the animation, it would delete the animation controller and the textfield.
That did require some extensive programming and I did it using the API and not the scripting inside Xpression.
I did it this way to get some more control over my crawl.
Just to give you another option.
Best regards,
Kenneth
