Im hestitant to say, but the use case is breast physics. Id need two edgeloops of particles to be pinned in order to deal with the issues of the edge particles not sharing a neibourhood/constraint with the particles right next to them.
This doesn't really work for me since the pin constrains work based on a specific joint, rather than the origional skinning of that area of the mesh, which ruins the weight painting in that area. So ive been trying to get the pinned verticies down to a single edge loop.
It works fine, so long as there is a lot of softbody resistance, but if it's low, then that lack of constraint causes a nasty seam when the bottom of the boob sinks down past the particle constraint. Which even happens if you constrain orientation.
Another result of this, is that since the pinned particles share less constraints than the other particles do, they will deform much more than the rest of the soft body. If something would sag by 1, then those next to the pinned particles would sag by 2, because they actually lack a constraint, making a gross shelf like result
