A few months ago I was planning on that but unfortunately the circumstances have changed and that's no longer the case.

Plasticity is doing them by using a geometry library called C3D. I had also wanted to use C3D to do the same things inside of MoI but it's become unfeasible to do that because C3D is the product of a Russian company and the Russia/Ukraine war has made it untenable to license it for use in MoI.

I might attempt to do my own implementation of direct face editing (the rotate face part) at some point here but I don't know when. There is a lot of work involved and so it's not very likely for the next version.

What is the situation with face rotation that is causing trouble in Plasticity, do you have an example of that?
