Vert2Vert - Modifier to Soft Select verts based on proximity to verts on a target mesh.
Vert2Vert is a MCG modifier that measures the distance from every vert in the modifier mesh to every vert in the target mesh, it then pipes the shortest distances into an affect region and then outputs soft selection. It works a bit like volume select, except it does not check is a vert is within a target volume - it just measures vert to vert and then soft selects accordingly. It's super fast too! Special thanks to Daniel Santana for helping out.
