VDB smoke uv mapping

[nailedit]

Hi guys

I'm trying out some stuff for my upcoming project and was wondering how to make uvs for smoke converted to poligons, so that they would remain stable rather than jumping around every frame. 

I found some info on using dual rest position, however I'm not sure how to tackle it, or if it could work with this approach.

Here is what I have right now ( I'm not sure if you can see that, but there are scratches on the surface of the smoke which as expected change where they are every frame, the question is how to make them remain in place even tho the number of points is changing and whole thing is deforming)

Here is the type of effect I'd like to achieve: 

Any tips are very much appreciated!
