Hello.

i need to create simple crawl like in picture below.

i have a clock with blue background on one scene, white background one another, and a text on the third and it is added to scene group with crawl effect.

what do i have to do to mask or crop the crawl area to fit the text only to the white background?

There are some examples of crawl masks in these projects:

RSS crawl and group controlled roll with event marker

More advanced crawl with scripts to control pauses and hides etc
