Can UMG function as After Effects?

Simple question: Can UMG function as After Effects?

I mean, if I want a text to pop out from nothing using the TextRender node, can I keyframe the opacity with the timeline in UMG?

The UE4 can be used like after effects :stuck_out_tongue:

e.g you can control the opacity with a parameter + a timeline which changes the value in your material

How do I set up a opacity material-parameter that I can keyframe in the timeline? Its just a simple RGB Maya-shader material.
