does anyone know what I'm talking about? Pretty sure it was using Hexagon, though I could be mistaken... I lost the link, and I need to find it.
There was one that showed smoothing shoes which you might be thinking of but I can't remember atm which/where it is. This one by Bobbie25 might help.
Not the same one I was thinking of, but basically the same process... so it works for me :)
