I have a plane facing upward z direction. I want to separate the faces on the plane that are sitting on the edge of the plane but also have edges facing the —y direction (I say —y because if you were to plot the edges on a 2D grid, the faces I want to separate would look like they are facing the —y direction). I was thinking of finding a way to rearrange the indices so the lowest values are the faces I want to separate, but the number of indices changes with every seed, so I can’t do that.
