Rigging Tool for Envelope Tool for Envelope

So what is the “Rigging Tool for Envelope” button that just appeared in Harmony 11.1 in the Deformer Toolbar? It wasn’t in Harmony 11.0 and I can’t seem to do anything special with it. It’s not even present in the online documentation as far as I can tel!

Any idea?

Thanks!

This is ability to surround a shape and deform it is now officially part of new Harmony 12 after the undocumented sneak peek noted by you above.

It’s used to encircle a shape and deform it; used for faces mostly - where precise detail is needed and the Warp effect is not providing the level of control necessary.
