Yes NC, that is exactly what I was talking about. Does that effect have a name?
With some of the advanced featured software out there, it may have a name.
In this case, I did it in steps basically by creating a transparency of one image overlaid on another.
(1), (2) Rendered the originals. Golf Ball & Sig Pic.
(3) Stretched the sig pic to make it look a bit spheroid
(4) Cut the stretched image to the size of the Golf Ball
(5) Created a 50% opaque transparency of the trimmed Sig Pic (4) overlaid onto the Ball (1).
(6) Blurred the overlay's edges for effect & cleaned up imperfections.
That's one of probably several ways to get it done.
