Controlling a scrolling texture's U value within a blueprint function without timeline

[Soaron]

In case anyone bumps into the same thing, this other forum post had the anser:

Timeline in a function?

Functions can only contain calls that finish instantly, and things like timelines and delays do not. If you need a function to execute a timeline, you can for example place a custom event (that triggers a timeline) in the main event graph, and then have your function raise such an event to start the timeline.

Confirmed it works!
