EDIT ::::: Sorry (wrong reply button) that is meant towards @colossaladvent!
hi man, I don't see why this node connections wont work on the current version of shader forge.
all you have to do is use the same theoretical idea.
pan the UV coordinates of a "noise" texture.
Lerp the Red Channel with another UV coordinates and the "T" will be your slider value.
then plug it into the Texture 2D node and split the Alpha and Albedo.
Your Question is not clear please provide screen shot of your status and better explanation will help us to help you.
Just asking someone for the job, and then copy paste is not the right way of getting answers
you are also confused. Billboard will be likely a 2D sprite and that means, if you want to use a mesh "Quad" you will have only four vertices - that said what you want to do exactly with 4 vertices ?
you talk about vertex displacement but the video you linked is UV coordinates distortion. I don't get what you are saying, sorry.
