Haha, thanks! The metal morphing is just a Polygon2D w/ texture, with an attached script that generates a bunch of polygon points on the top. When you hit the metal with the hammer, the script grabs the closest polygon point (+ a few neighbors depending on the hammer type), and pushes them down by however hot the metal is - and lerps the neighbors down by how far from the hammer the neighbor is.. also updates a matching collision polygon’s points for detecting when the metal “fits” into the depicted shape.
