Hair emitted outside vertex group I am seeing hair emitted from faces outside the vertex group. I created a simple UV sphere, a vertex group (colored), a hair particle system using the vertex group as the density, no children. You can see below hair growing out of faces adjacent to the vertex group and I don't know why. Anyone?
Mr Zak has the right answer. The outer edge loop of my vertex group is weighted and allows some hairs to be emitted.

One workaround is to duplicate the faces in the mesh, assign them to a new vertex group and use that for the particle system:
