Can this be done with Tyflow? "sticky" UVW

[Johncro]

I'm not even sure you'd need tyFlow for something like that...could probably be done with animated displacement?

Perhaps  a heavily retimed cloth sim, to get some more dynamic undulations?  There are probably a variety of ways to create that, and it looks like most of the work is done by the shader.

"Perhaps a heavily retimed cloth sim" - that's exactly what I did, at first

Ok, so I guess that's the right way to do it!

Thanks a lot for your help!
