f-Edge
f-Edge is a 3ds Max plug-in that gets rid of the sharp and flat edge look of standard angular objects. As in the real world, f-Edge simulates the slight soft curvature over the selected edges of the object. It comes with a very small rendering time penalty and gives that non-"computer generated" soft look to the object. Especially suited for large-scale city and architecture projects where edge smoothing by hand is almost impossible.Download f-Edge version 1.06 for 3ds max 2016 - 2025.
