Hi guys,

I wanted to try and make some text effect, like the opening part of this video, the revealing typo at the beginning.

I animated the displacement map do dent or rise the surface with the text text, but I have no idea how to control, as it is a mask that reveals the text in a path.
Can you help me with this challenge please.
At one point I was thinking that can be done in a post, but then the rendered footage needs to be tracked if to apply a mask in AE or Nuke.
Thanks a lot.
